* cluster/dht: Add migration checks to dht_(f)xattropN Balachandran2018-01-305-53/+334
| | | | | | | | | | | | | | | | The dht_(f)xattrop implementation did not implement migration phase1/phase2 checks which could cause issues with rebalance on sharded volumes. This does not solve the issue where fops may reach the target out of order. > Change-Id: I2416fc35115e60659e35b4b717fd51f20746586c > BUG: 1471031 > Signed-off-by: N Balachandran <nbalacha@redhat.com> Change-Id: I2416fc35115e60659e35b4b717fd51f20746586c BUG: 1498081 Signed-off-by: N Balachandran <nbalacha@redhat.com>
* cluster/afr: Honor default timeout of 5min for analyzing split-brain fileskarthik-us2017-11-271-1/+5
| | | | | | | | | | | | | | | | | | | | Problem: After setting split-brain-choice option to analyze the file to resolve the split brain using the command "setfattr -n replica.split-brain-choice -v "choiceX" <path-to-file>" should allow to access the file from mount for default timeout of 5mins. But the timeout was not honored and was able to access the file even after the timeout. Fix: Call the inode_invalidate() in afr_set_split_brain_choice_cbk() so that it will triger the cache invalidate after resetting the timer and the split brain choice. So the next calls to access the file will fail with EIO.

* afr: auto-resolve split-brains for zero-byte filesRavishankar N2017-10-023-0/+79
| | | | | | | | | | | | | | | | | | | | | | | | | | Backport of https://review.gluster.org/#/c/18283/ Problems: As described in BZ 1491670, renaming hardlinks can result in data/mdata split-brain of the DHT link-to files (T files) without any mismatch of data and metadata. As described in BZ 1486063, for a zero-byte file with only dirty bits set, arbiter brick will likely be chosen as the source brick. Fix: For zero byte files in split-brain, pick first brick as a) data source if file size is zero on all bricks. b) metadata source if metadata is the same on all bricks In arbiter case, if file size is zero on all bricks and there are no pending afr xattrs, pick 1st brick as data source.

* cluster/dht: Check for open fd only on EBADFN Balachandran2017-09-174-160/+160
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DHT fd based fops used to check if the fd was open on the cached subvol before winding the call. However, this introduced a performance regression of about 30% for reads. This check was introduced to handle cases where files were migrated while IOs were happening. As this is not the common case, dht will now check if the fd is open on the cached subvol only if the call fails with EBADF. This will prevent a performance hit where a rebalance is not running. > BUG: 1476665 > Signed-off-by: N Balachandran <nbalacha@redhat.com> > Reviewed-on: https://review.gluster.org/17976 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Amar Tumballi <amarts@redhat.com> > Reviewed-by: Susant Palai <spalai@redhat.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Change-Id: I2035a858d63c3fcd22bb634055bbb0ad01686808 BUG: 1467010 Signed-off-by: N Balachandran <nbalacha@redhat.com> Reviewed-on: https://review.gluster.org/18057 CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

* cluster/ec: return all node uuids from all subvolumesXavier Hernandez2017-09-012-105/+141
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | EC was retuning the UUID of the brick with smaller value. This had the side effect of not evenly balancing the load between bricks on rebalance operations. This patch modifies the common functions that combine multiple subvolume values into a single result to take into account the subvolume order and, optionally, other subvolumes that could be damaged. This makes easier to add future features where brick order is important. It also makes possible to easily identify the originating brick of each answer, in case some brick will have an special meaning in the future. >Change-Id: Iee0a4da710b41224a6dc8e13fa8dcddb36c73a2f >BUG: 1366817 >Signed-off-by: Xavier Hernandez <xhernandez@datalab.es> >Reviewed-on: https://review.gluster.org/17297 >Smoke: Gluster Build System <jenkins@build.gluster.org> >NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> >CentOS-regression: Gluster Build System <jenkins@build.gluster.org> >Reviewed-by: Ashish Pandey <aspandey@redhat.com> >Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> BUG: 1487042 Change-Id: Iee0a4da710b41224a6dc8e13fa8dcddb36c73a2f Signed-off-by: Sunil Kumar Acharya <sheggodu@redhat.com> Reviewed-on: https://review.gluster.org/18148 CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Xavier Hernandez <xhernandez@datalab.es> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
* cluster/rebalance: Fix hardlink migration failuresSusant Palai2017-08-112-15/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A brief about how hardlink migration works: - Different hardlinks (to the same file) may hash to different bricks, but their cached subvol will be same. Rebalance picks up the first hardlink, calculates it's hash(call it TARGET) and set the hashed subvolume as an xattr on the data file. - Now all the hardlinks those come after this will fetch that xattr and will create linkto files on TARGET (all linkto files for the hardlinks will be hardlink to each other on TARGET). - When number of hardlinks on source is equal to the number of hardlinks on TARGET, the data migration will happen. RACE:1 Since rebalance is multi-threaded, the first lookup (which decides where the TARGET subvol should be), can be called by two hardlink migration parallely and they may end up creating linkto files on two different TARGET subvols. Hence, hardlinks won't be migrated. Fix: Rely on the xattr response of lookup inside gf_defrag_handle_hardlink since it is executed under synclock. RACE:2 The linkto files on TARGET can be created by other clients also if they are doing lookup on the hardlinks. Consider a scenario where you have 100 hardlinks. When rebalance is migrating 99th hardlink, as a result of continuous lookups from other client, linkcount on TARGET is equal to source linkcount. Rebalance will migrate data on the 99th hardlink itself. On 100th hardlink migration, hardlink will have TARGET as cached subvolume. If it's hash is also the same, then a migration will be triggered from TARGET to TARGET leading to data loss. Fix: Make sure before the final data migration, source is not same as destination. RACE:3 Since a hardlink can be migrating to a non-hashed subvolume, a lookup from other client or even the rebalance it self, might delete the linkto file on TARGET leading to hardlinks never getting migrated. This will be addressed in a different patch in future. > Change-Id: If0f6852f0e662384ee3875a2ac9d19ac4a6cea98 > BUG: 1469964 > Signed-off-by: Susant Palai <spalai@redhat.com> > Reviewed-on: https://review.gluster.org/17755 > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: N Balachandran <nbalacha@redhat.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Signed-off-by: Susant Palai <spalai@redhat.com> Change-Id: If0f6852f0e662384ee3875a2ac9d19ac4a6cea98 BUG: 1473141 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: https://review.gluster.org/17838 CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* cluster/dht: fix on demand migration files from clientSusant Palai2017-08-114-20/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On demand migration of files i.e. migration done by clients triggered by a setfattr was broken. Dependency on defrag led to crash when migration was triggered from client. Note: This functionality is not available for tiered volumes. Migration from tier served client will fail with ENOTSUP. usage (But refer to the steps mentioned below to avoid any issues) : setfattr -n "trusted.distribute.migrate-data" -v "1" <filename> The purpose of fixing the on-demand client migration was to give a workaround where the user has lots of empty directories compared to files and want to do a remove-brick process. Here are the steps to trigger file migration for remove-brick process from client. (This is highly recommended to follow below steps as is) Let's say it is a replica volume and user want to remove a replica pair named brick1 and brick2. (Make sure healing is completed before you run these steps) Step-1: Start remove-brick process - gluster v remove-brick <volname> brick1 brick2 start Step-2: Kill the rebalance daemon - ps aux | grep glusterfs | grep rebalance\/ | awk '{print $2}' | xargs kill Step-3: Do a fresh mount as mentioned here - glusterfs -s ${localhostname} --volfile-id rebalance/$volume-name /tmp/mount/point Step-4: Go to one of the bricks (among brick1 and brick2) - cd <brick1 path> Step-5: Run the following command. - find . -not \( -path ./.glusterfs -prune \) -type f -not -perm 01000 -exec bash -c 'setfattr -n "distribute.fix.layout" -v "1" ${mountpoint}/$(dirname '{}')' \; -exec setfattr -n "trusted.distribute.migrate-data" -v "1" ${mountpoint}/'{}' \; This command will ignore the linkto files and empty directories. Do a fix-layout of the parent directory. And trigger a migration operation on the files. Step-6: Once this process is completed do "remove-brick force" - gluster v remove-brick <volname> brick1 brick2 force Note: Use the above script only when there are large number of empty directories. Since the script does a crawl on the brick side directly and avoids directories those are empty, the time spent on fixing layout on those directories are eliminated(even if the script does not do fix-layout on empty directories, post remove-brick a fresh layout will be built for the directory, hence not affecting application continuity). Detailing the expectation for hardlink migartion with this patch: Hardlink is migrated only for remove-brick process. It is highly essential to have a new mount(step-3) for the hardlink migration to happen. Why?: setfattr operation is an inode based operation. Since, we are doing setfattr from fuse mount here, inode_path will try to build path from the linked dentries to the inode. For a file without hardlinks the path construction will be correct. But for hardlinks, the inode will have multiple dentries linked. Without fresh mount, inode_path will always get the most recently linked dentry. e.g. if there are three hardlinks named dir1/link1, dir2/link2, dir3/link3, on a client where these hardlinks are looked up, inode_path will always return the path dir3/link3 if dir3/link3 was looked up most recently. Hence, we won't be able to create linkto files for all other hardlinks on destination (read gf_defrag_handle_hardlink for more details on hardlink migration). With a fresh mount, the lookup and setfattr become serialized. e.g. link2 won't be looked up until link1 is looked up and migrated. Hence, inode_path will always have the correct path, in this case link1 dentry is picked up(as this is the most recently looked up inode) and the path is built right. Note: If you run the above script on an existing mount(all entries looked up), hard links may not be migrated, but there should not be any other issue. Please raise a bug, if you find any issue.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current rebalance throttle options: lazy/normal/aggressive may not always be sufficient for the purpose of throttling. In our recent test, we observed for certain setups, normal and aggressive modes behaved similarly consuming full disk bandwidth. So in cases like this admin should be able to tune it down(or vice versa) depending on the need. Along with old throttle configurations, thread counts are tuned based on number. e.g. gluster v set vol-name cluster-rebal.throttle 5. Admin can tune up/down between 0 and the number of cores available. Note: For heterogenous servers, validation will fail on the old server if "number" is given for throttle configuration. The message looks something like this: "volume set: failed: Staging failed on vm2. Error: cluster.rebal-throttle should be {lazy|normal|aggressive}" Test: Manual test by logging active thread number after reconfiguring throttle option. testcase: tests/basic/distribute/throttle-rebal.t > Change-Id: I46e3cde546900307831028b344ecf601fd9b02c3 > BUG: 1438370 > Signed-off-by: Susant Palai <spalai@redhat.com> > Reviewed-on: https://review.gluster.org/16980 > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > Smoke: Gluster Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Atin Mukherjee <amukherj@redhat.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Signed-off-by: Susant Palai <spalai@redhat.com> Change-Id: I46e3cde546900307831028b344ecf601fd9b02c3 BUG: 1473136 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: https://review.gluster.org/17835 CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>
* cluster/dht: rebalance perf enhancementSusant Palai2017-08-112-108/+246
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Throttle settings "normal" and "aggressive" for rebalance did not have performance difference. normal mode spawns $(no. of cores - 4)/2 threads and aggressive spawns $(no. of cores - 4) threads. Though aggressive mode has twice the number of threads compared to that of normal mode, there was no performance gain when switched to aggressive mode from normal mode. RCA: During the course of debugging the above problem, we tried assigning migration job to migration threads spawned by rebalance, rather than synctasks(as there is more overhead associated to manage the task queue and threads). This gave us a significant improvement over rebalance under synctasks. This patch does not really gurantee that there will be a clear performance difference between normal and aggressive mode, but this patch certainly maximized the disk utilization for 1GBfiles run. Results: Test enviroment: Gluster Config: Number of Bricks: 2 (one brick per disk(RAID-6 12 disk)) Bricks: Brick1: server1:/brick/test1/1 Brick2: server2:/brick/test1/1 Options Reconfigured: performance.readdir-ahead: on server.event-threads: 4 client.event-threads: 4 1000 files with 1GB each were created/renamed such that all files will have server1 as cached and server2 as hashed, so that all files will be migrated. Test machines had 24 cores each. Results with/without synctask based migration: ----------------------------------------------- mode normal(10threads) aggressive(20threads) timetaken 0:55:30 (h:m:s) 0:56:3 (h:m:s) withsynctask timetaken with migrator 0:38:3 (h:m:s) 0:23:41 (h:m:s) threads From above table it can be seen that, there is a clear 2x perf gain between rebalance with synctask vs rebalance with migrator threads. Additionally this patch modifies the code so that caller will have the exact error number returned by dht_migrate_file(earlier the errno meaning was overloaded). This will help avoiding scenarios where migration failure due to ENOENT, can result in rebalance abort/failure. > Change-Id: I8904e2fb147419d4a51c1267be11a08ffd52168e > BUG: 1420166 > Signed-off-by: Susant Palai <spalai@redhat.com> > Reviewed-on: https://review.gluster.org/16427 > Smoke: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: N Balachandran <nbalacha@redhat.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Signed-off-by: Susant Palai <spalai@redhat.com> Change-Id: I8904e2fb147419d4a51c1267be11a08ffd52168e BUG: 1473134 Signed-off-by: Susant Palai <spalai@redhat.com> Reviewed-on: https://review.gluster.org/17834 CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>

And we do a lookup on the entries received to figure out the eligibilty. Since, the lookup done is on a local subvolume we receive linkto files and regular files as well. This requires us to do two lookups. first: do a lookup on the file to figure out whether it is a linkto file second: do a lookup on the file to figure out if it should be migrated Note: The migrator thread also does one lookup for the file before migration. Optimization: Remove the lookup done by the crawler. Offload these task to the migrator threads. For linkto file verification get the stat and xattr information from readdirp. So in total we have one lookup instead of three for each entry. Performance numbers: Create two node, two brick setup. Created 100000 files. And started rebalance. Since, there is no add-brick, no files will be migrated and we will get the crawler performance.

* afr: add errno to afr_inode_refresh_done()Ravishankar N2017-06-161-7/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of https://review.gluster.org/17413 and https://review.gluster.org/17436 Problem: When parellel `rm -rf`s were being done from cifs clients, opendir might fail on some replicas with ENOENT. DHT ignores partial opendir failures in dht_fd_cbk() and winds readdirs on those replicas. Afr inode refresh (as a part of readdirp read_txn) sees in its fd context that the state of the fds is *not* AFR_FD_OPENED and bails out to afr_inode_refresh_done() without doing a refresh. When this happens, the errno is set as EIO due to lack of readable subvols, logging split-brain messages in the logs. Fix: Introduce an errno argument to afr_inode_refresh_do() to bail out with the right error value when inode refresh is not performed.

* cluster/dht: Rebalance on all nodes should migrate filesN Balachandran2017-05-186-20/+215
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Rebalance compares the node-uuid of a file against its own to and migrates a file only if they match. However, the current behaviour in both AFR and EC is to return the node-uuid of the first brick in a replica set for all files. This means a single node ends up migrating all the files if the first brick of every replica set is on the same node. Fix: AFR and EC will return all node-uuids for the replica set. The rebalance process will divide the files to be migrated among all the nodes by hashing the gfid of the file and using that value to select a node to perform the migration. This patch makes the required DHT and tiering changes. Some tests in rebal-all-nodes-migrate.t will need to be uncommented once the AFR and EC changes are merged. > BUG: 1366817 > Signed-off-by: N Balachandran <nbalacha@redhat.com> > Reviewed-on: https://review.gluster.org/17239 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Amar Tumballi <amarts@redhat.com> > Reviewed-by: Jeff Darcy <jeff@pl.atyp.us> > Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> (cherry picked from commit b23bd3dbc2c153171d0bb1205e6804afe022a55f) Change-Id: I5ce41600f5ba0e244ddfd986e2ba8fa23329ff0c BUG: 1451561 Signed-off-by: N Balachandran <nbalacha@redhat.com> Reviewed-on: https://review.gluster.org/17311 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com>

But if the FOP failed on a brick due to an error other than ENOTCONN (or even due to ENOTCONN, but we regained connection before postop was wound), we wind the post-op also on the failed brick, leading to setting self-blaming xattrs on that brick. This can lead to undesired results like healing of files in split-brain etc. Fix: If a fop failed on a brick on which pre-op was successful, do not perform post-op on it. This also produces the desired effect of not resetting the dirty xattr on the brick, which is how it should be because if the fop failed on a brick, there is no reason to clear the dirty bit which actually serves as an indication of the failure. > Reviewed-on: https://review.gluster.org/16976 > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> (cherry picked from commit 10dad995c989e9d77c341135d7c48817baba966c) Change-Id: I5f1caf4d1b39f36cf8093ccef940118638caa9c4 BUG: 1443501 Signed-off-by: Ravishankar N <ravishankar@redhat.com> Reviewed-on: https://review.gluster.org/17083 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>

This is leading to EC erroring out the lookup with EINVAL which leads to NFS failing lookup with EIO. snip from gdb: $37 = (dht_local_t *) 0x7fde5de5b3cc (gdb) p /x $37->loc.gfid $39 = {0x3b, 0x82, 0x10, 0x5e, 0x40, 0x65, 0x43, 0x14, 0xa0, 0xc6, 0x8, 0xf5, 0x6c, 0x2c, 0xb8, 0x56} (gdb) fr 7 state=<optimized out>) at ec-generic.c:837 837 ec_lookup_rebuild(fop->xl->private, fop, cbk); (gdb) p /x fop->loc[0].gfid $40 = {0x0, 0x0, 0x0, 0x0, 0x0, 0x0, 0x43, 0x14, 0xa0, 0xc6, 0x8, 0xf5, 0x6c, 0x2c, 0xb8, 0x56} snip from log: [2017-01-29 03:22:30.132328] W [MSGID: 122019] [ec-helpers.c:354:ec_loc_gfid_check] 0-butcher-disperse-4: Mismatching GFID's in loc [2017-01-29 03:22:30.132709] W [MSGID: 112199] [nfs3-helpers.c:3515:nfs3_log_newfh_res] 0-nfs-nfsv3: /linux-4.9.5/Documentation => (XID: b27b9474, MKDIR: NFS: 5(I/O error), POSIX: 5(Input/output error)), FH: exportid 00000000-0000-0000-0000-000000000000, gfid 00000000-0000-0000-0000-000000000000, mountid 00000000-0000-0000-0000-000000000000 [Invalid argument] Fix: update local->loc.gfid in last-call to make sure there are no races. >BUG: 1438411 >Change-Id: Ifcb7e911568c1f1f83123da6ff0cf742b91800a0 >Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> BUG: 1438423 Change-Id: I804822a1d50215301881ac18318282c1a6951cfb Signed-off-by: Pranith Kumar K <pkarampu@redhat.com> Reviewed-on: https://review.gluster.org/16987 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Raghavendra G <rgowdapp@redhat.com>

* cluster/afr: Undo pending xattrs only on the up brickskarthik-us2017-03-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: While doing conservative merge, even if a brick is down, it will reset the pending xattr on that. When that brick comes up, as part of the heal, it will consider this brick as the source and removes the entries on the other bricks, which leads to data loss. Fix: Undo pending only for the bricks which are up. > Change-Id: I18436fa0bb1faa5f60531b357dea3f6b20446303 > BUG: 1433571 > Signed-off-by: karthik-us <ksubrahm@redhat.com> > Reviewed-on: https://review.gluster.org/16913 > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> > Reviewed-by: Ravishankar N <ravishankar@redhat.com> (cherry picked from commit f91596e6566c605e70a31a60523d11f78a097c3c) Change-Id: I51dbdc53e84051ec73308df9d4cf27726fc29dc7 BUG: 1436203 Signed-off-by: karthik-us <ksubrahm@redhat.com> Reviewed-on: https://review.gluster.org/16955 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> Reviewed-by: Ravishankar N <ravishankar@redhat.com>
* afr: do not mention split-brain in log message in read_txnRavishankar N2017-03-271-3/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I am seeing a lot of messages in qe/customer logs where read_txn complains that file is possibly in split-brain because of no readable subvol being found, does inode refresh and then there is no split-brain message post the inode refresh. This means that a lookup was not issued on the indoe to populate 'readable' or it can mean one brick is source for data and the other for metadata, making readable to be zero (because readable=intersection of (data,metadata readable) since commit 7a1c1e290470149696. Since we anyway log actual split-brains post inode-refresh, move this message to DEBUG log level. > Signed-off-by: Ravishankar N <ravishankar@redhat.com> > Reviewed-on: https://review.gluster.org/16879 > Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Tested-by: Pranith Kumar Karampuri <pkarampu@redhat.com> > Smoke: Gluster Build System <jenkins@build.gluster.org> > NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> > CentOS-regression: Gluster Build System <jenkins@build.gluster.org> (cherry picked from commit 71e023fcaab0058f32fedc7b6b702040fdd85f46) Change-Id: Idb88b8ea362515279dc9b246f06b6b646c6d8013 BUG: 1434303 Reviewed-on: https://review.gluster.org/16934 Tested-by: Ravishankar N <ravishankar@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
