| | | | | | | | | | | | | | | | | | | | | | | inode quota is a new feature implemented in glusterfs-3.7 if quota is enabled in the older version and is upgraded to a new version, we can hit setxattr spike during self-heal of inode quotas. So, when a quota is enabled, turn off inode-quotas with a xlator option. With this patch, we still account for inode quotas but only when a write operation is performed for a particular file. User will be able to query inode quotas once the Inode-quota xlator option is enabled.

* cluster/tier: don't use hot tier until subvolumes readyDan Lambright2015-05-082-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a backport of fix 10435 to Gluster 3.7. When we attach a tier, the hot tier becomes the hashed subvolume. But directories may not yet have been replicated by the fix layout process. Hence lookups to those directories will fail on the hot subvolume. We should only go to the hashed subvolume once the layout has been fixed. This is known if the layout for the parent directory does not have an error. If there is an error, the cold tier is considered the hashed subvolume. The exception to this rules is ENOCON, in which case we do not know where the file is and must abort. Note we may revalidate a lookup for a directory even if the inode has not yet been populated by FUSE. This case can happen in tiering (where one tier has completed a lookup but the other has not, in which case we revalidate one tier when we call lookup the second time). Such inodes are still invalid and should not be consulted for validation. > http://review.gluster.org/#/c/10435/ > Change-Id: Ia2bc62e1d807bd70590bd2a8300496264d73c523 > BUG: 1214289 > Signed-off-by: Dan Lambright <dlambrig@redhat.com> > Reviewed-on: http://review.gluster.org/10435 > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Reviewed-by: N Balachandran <nbalacha@redhat.com> > Signed-off-by: Dan Lambright <dlambrig@redhat.com> Change-Id: Ia2bc62e1d807bd70590bd2a8300496264d73c523 BUG: 1219547 Signed-off-by: Dan Lambright <dlambrig@redhat.com> Reviewed-on: http://review.gluster.org/10649 Tested-by: NetBSD Build System Reviewed-by: Joseph Fernandes Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* geo-rep: rename handling in dht volumeNithya Balachandran2015-05-083-0/+108
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Background: Glusterfs changelogs are stored in each brick, which records the changes happened in that brick. Georep will run in all the nodes of master and processes changelogs "independently". Processing changelogs is in brick level, but all the fops will be replayed on "slave mount" point. Problem: With a DHT volume, in changelog "internal fops" are NOT recorded. For Rename case, Rename is recorded in "hashed" brick changelog. (DHT's internal fops like creating linkto file, unlink is NOT recorded). This lead us to inconsistent rename operations. For example, Distribute volume created with Two bricks B1, B2. //Consider master volume mounted @ /mnt/master and following operations executed: cd /mnt/master touch f1 // f1 falls on B1 Hash mv f1 f2 // f2 falls on B2 Hash // Here, Changelogs are recorded as below: @B1 CREATE f1 @B2 RENAME f1 f2 Here, race exists between Brick B1 and B2, say B2 will get executed first. Source file f1 itself is "NOT PRESENT", so it will go ahead and create f2 (Current implementation). We have this problem When rename falls in another brick and file is unlinked in Master. Similar kind of issue exists in following case too(multiple rename): CREATE f1 RENAME f1 f2 RENAME f2 f1 Solution: Instead of carrying out "changelogging" at "HASHED volume", carry out at the "CACHED volume". This way we have rename operations carried out where actual files are present. So,Changelog recorded as : @B1 CREATE f1 RENAME f1 f2 credit: sarumuga@redhat.com PS: Some of the races as the one below are _NOT_ fixed by this patch * f1 and f2 exist. B1 and B2 are their respective cached subvols. For both files hashed-subvol == cached-subvol * mv f1 f2 on master. * B1 has change-log entry of rename f1 f2 * rebalance migrates f2 from B1 and B2 * mv f2 f1 on master. * B2 has change-log entry of rename f2 f1 Since changelog entries (rename f1 f2) and (rename f2 f1) are processed independently by gsyncds, which of either f1 and f2 survives on slave is subject to race. Note that on master its file f1 with name f1 which survived. On slave it can be either file f1 with name f1 or file f2 with name f2 based on who wins the race of processing changelog.

For tiered volumes, when we try to reopen the file (on the destination), the lower level DHT receives the open call and fails; it does not have a "cached subvol". Fix is to "teach" the lower level DHT of the new location by sending a locate before the open. > http://review.gluster.org/#/c/10324/ > Change-Id: Ia4acb0035ff1da15f6a8f9ed54f43c76e8b98f5f > BUG: 1214048 > Signed-off-by: Dan Lambright <dlambrig@redhat.com> > Signed-off-by: root <root@gprfs018.sbu.lab.eng.bos.redhat.com> > Signed-off-by: Dan Lambright <dlambrig@redhat.com> > Reviewed-on: http://review.gluster.org/10324 > Tested-by: NetBSD Build System > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Reviewed-by: Raghavendra G <rgowdapp@redhat.com> > Tested-by: Raghavendra G <rgowdapp@redhat.com> > Signed-off-by: Dan Lambright <dlambrig@redhat.com> Change-Id: Ia4acb0035ff1da15f6a8f9ed54f43c76e8b98f5f BUG: 1219608 Signed-off-by: Dan Lambright <dlambrig@redhat.com> Reviewed-on: http://review.gluster.org/10654 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System Reviewed-by: Joseph Fernandes Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* ctr/xlator: Named lookup heal of pre-existing files, before ctr was ON.Joseph Fernandes2015-05-088-6/+1021
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: The CTR xlator records file meta (heat/hardlinks) into the data. This works fine for files which are created after ctr xlator is switched ON. But for files which were created before CTR xlator is ON, CTR xlator is not able to record either of the meta i.e heat or hardlinks. Thus making those files immune to promotions/demotions. Solution: The solution that is implemented in this patch is do ctr-db heal of all those pre-existent files, using named lookup. For this purpose we use the inode-xlator context variable option in gluster. The inode-xlator context variable for ctr xlator will have the following, a. A Lock for the context variable b. A hardlink list: This list represents the successful looked up hardlinks. These are the scenarios when the hardlink list is updated: 1) Named-Lookup: Whenever a named lookup happens on a file, in the wind path we copy all required hardlink and inode information to ctr_db_record structure, which resides in the frame->local variable. We dont update the database in wind. During the unwind, we read the information from the ctr_db_record and , Check if the inode context variable is created, if not we create it. Check if the hard link is there in the hardlink list. If its not there we add it to the list and send a update to the database using libgfdb. Please note: The database transaction can fail(and we ignore) as there already might be a record in the db. This update to the db is to heal if its not there. If its there in the list we ignore it. 2) Inode Forget: Whenever an inode forget hits we clear the hardlink list in the inode context variable and delete the inode context variable. Please note: An inode forget may happen for two reason, a. when the inode is delete. b. the in-memory inode is evicted from the inode table due to cache limits. 3) create: whenever a create happens we create the inode context variable and add the hardlink. The database updation is done as usual by ctr. 4) link: whenever a hardlink is created for the inode, we create the inode context variable, if not present, and add the hardlink to the list. 5) unlink: whenever a unlink happens we delete the hardlink from the list. 6) mknod: same as create. 7) rename: whenever a rename happens we update the hardlink in list. if the hardlink was not present for updation, we add the hardlink to the list. What is pending: 1) This solution will only work for named lookups. 2) We dont track afr-self-heal/dht-rebalancer traffic for healing. > http://review.gluster.org/#/c/10370/ > Cherry picked from commit cb11dd91a6cc296e4a3808364077f4eacb810e48 > Change-Id: Ia4bbaf84128ad6ce8c3ddd70bcfa82894c79585f > BUG: 1212037 > Signed-off-by: Joseph Fernandes <josferna@redhat.com> > Signed-off-by: Dan Lambright <dlambrig@redhat.com> > Reviewed-on: http://review.gluster.org/10370 > Reviewed-by: Jeff Darcy <jdarcy@redhat.com> > Tested-by: Gluster Build System <jenkins@build.gluster.com> > Tested-by: NetBSD Build System > Reviewed-by: Vijay Bellur <vbellur@redhat.com> Change-Id: I367aa46c3f4b8f912248fb8be75866507f2538df BUG: 1219075 Signed-off-by: Joseph Fernandes <josferna@redhat.com> Signed-off-by: Dan Lambright <dlambrig@redhat.com> Reviewed-on: http://review.gluster.org/10370 Reviewed-by: Jeff Darcy <jdarcy@redhat.com> Reviewed-by: Vijay Bellur <vbellur@redhat.com> Signed-off-by: Joseph Fernandes <josferna@redhat.com> Reviewed-on: http://review.gluster.org/10615 Tested-by: Vijay Bellur <vbellur@redhat.com>

* geo-rep: Limit number of changelogs to process in batchAravinda VK2015-05-071-6/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changelog processing is done in batch, for example if 10 changelogs available for processing then process all at once. Collect Entry, Meta and Data operations separately, All the entry operations like CREATE, MKDIR, MKNOD, LINK, UNLINK will be executed first then rsync will be triggered for whole batch. Stime will get updated once the complete batch is complete. In case of large number of Changelogs in a batch, If geo-rep fails after Entry operations, but before rsync then on restart, it again starts from the beginning since stime is not updated. It has to process all the changelogs again. While processing same changelogs again, all CREATE will get EEXIST since all the files created in previous run. Big hit for performance. With this patch, Geo-rep limits number of changelogs per batch based on Changelog file size. So that when geo-rep fails it has to retry only last batch changelogs since stime gets updated after each batch.

* Tests: use a portable way to flush kernel cacheEmmanuel Dreyfus2015-05-073-16/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On Linux, kernel cache can be flushed using echo 3 > /proc/sys/vm/drop_caches This non-portable approach can be replaced by an on-purpose failed attempt to unmount: if the mount point is the current directory and umount is called, the kernel will flush inodes until it realize it cannot complete the operation because root of filesystem is busy: ( cd $M0 ; umount $M0 ) Unfortunately this does not flush everything. Entries may still be present in the kenrel FUSE cache. Using $GFS to mount the filesystem ensure --entry-timeout=0 and clears this problem. Some stall information may also remain in glusterfs caches, and that may have to be adressed by appropriate volume option. For instance tests/bugs/rpc/bug-954057.t needs to disable performance.stat-prefetch. Qtherwise, root's new credentials are not evaluated after root-quash is enabled. The test could also be done with performance.stat-prefetch enabled using various tricks: copying the file to read, creating a hard link on it, or just waiting long enough for metadata cache to expire.

As a result the frame->root->pid is not set. Solution: When the file is getting migrated, we get a tiering.migration key_value in the xattr dict, so that we pass this dic key-value when we do syncop_setxattr() to do data migration and set the frame->root->pid GF_CLIENT_PID_TIER_DEFRAG in dht_setxattr() just before calling dht_start_rebalance_task(). > http://review.gluster.org/#/c/10266/ > Change-Id: I86fef2d961b32fdd2c0c69d8512cbe846b393404 > BUG: 1194753 > Signed-off-by: Joseph Fernandes <josferna@redhat.com> > Reviewed-on: http://review.gluster.org/10266 > Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> > Reviewed-by: Susant Palai <spalai@redhat.com> > Reviewed-by: Dan Lambright <dlambrig@redhat.com> > Tested-by: Gluster Build System <jenkins@build.gluster.com> Change-Id: I6ab42b2c7a3c3e21c461d097b7558ee967b62c62 BUG: 1218959 Signed-off-by: Joseph Fernandes <josferna@redhat.com> Reviewed-on: http://review.gluster.org/10266 Reviewed-by: Shyamsundar Ranganathan <srangana@redhat.com> Reviewed-by: Susant Palai <spalai@redhat.com> Reviewed-by: Dan Lambright <dlambrig@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Signed-off-by: Joseph Fernandes <josferna@redhat.com> Reviewed-on: http://review.gluster.org/10601 Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* cluster/ec: Perform inode-write on healing subvolsPranith Kumar K2015-05-073-129/+88
| | | | | | | | | | | | | | | | | | | Backport of http://review.gluster.org/10372 If the version numbers do not match, then writes are performed only on at least N-R bricks which have same version. But if we want to do healing of files which are constantly modified we need to allow writes on subvols that are undergoing heal. Data healing will mark 62nd bit while the heal is going on. When the data transaction sees that this bit is set it needs to perform the fop on that subvol irrespective of whether the versions match or do not match. Fop is considered successful only if N-R non-healing bricks succeed.

* rebalance: Introducing local crawl and parallel migrationSusant Palai2015-05-078-252/+1137
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current patch address two part of the design proposed. 1. Rebalance multiple files in parallel 2. Crawl only bricks that belong to the current node Brief design explanation for the above two points. 1. Rebalance multiple files in parallel: ------------------------------------- The existing rebalance engine is single threaded. Hence, introduced multiple threads which will be running parallel to the crawler. The current rebalance migration is converted to a "Producer-Consumer" frame work. Where Producer is : Crawler Consumer is : Migrating Threads Crawler: Crawler is the main thread. The job of the crawler is now limited to fix-layout of each directory and add the files which are eligible for the migration to a global queue in a round robin manner so that we will use all the disk resources efficiently. Hence, the crawler will not be "blocked" by migration process. Producer: Producer will monitor the global queue. If any file is added to this queue, it will dqueue that entry and migrate the file. Currently 20 migration threads are spawned at the beginning of the rebalance process. Hence, multiple file migration happens in parallel. 2. Crawl only bricks that belong to the current node: -------------------------------------------------- As rebalance process is spawned per node, it migrates only the files that belongs to it's own node for the sake of load balancing. But it also reads entries from the whole cluster, which is not necessary as readdir hits other nodes. New Design: As part of the new design the rebalancer decides the subvols that are local to the rebalancer node by checking the node-uuid of root directory prior to the crawler starts. Hence, readdir won't hit the whole cluster as it has already the context of local subvols and also node-uuid request for each file can be avoided. This makes the rebalance process "more scalable".
