* features/shard: Fill loc.pargfid too for named lookups on individual shardsKrutika Dhananjay2016-11-081-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On a sharded volume when a brick is replaced while IO is going on, named lookup on individual shards as part of read/write was failing with ENOENT on the replaced brick, and as a result AFR initiated name heal in lookup callback. But since pargfid was empty (which is what this patch attempts to fix), the resolution of the shards by protocol/server used to fail and the following pattern of logs was seen: Brick-logs: [2016-11-08 07:41:49.387127] W [MSGID: 115009] [server-resolve.c:566:server_resolve] 0-rep-server: no resolution type for (null) (LOOKUP) [2016-11-08 07:41:49.387157] E [MSGID: 115050] [server-rpc-fops.c:156:server_lookup_cbk] 0-rep-server: 91833: LOOKUP(null) (00000000-0000-0000-0000-000000000000/16d47463-ece5-4b33-9c93-470be918c0f6.82) ==> (Invalid argument) [Invalid argument] Client-logs: [2016-11-08 07:41:27.497687] W [MSGID: 114031] [client-rpc-fops.c:2930:client3_3_lookup_cbk] 2-rep-client-0: remote operation failed.

* md-cache, afr: Reduce the window of stale readPoornima G2016-10-202-2/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Consider a replica setup, where one mount writes data to a file and the other mount reads the file. In afr, read operations are not transaction based, a brick(read subvolume) is chosen as a part of lookup or other operations, read is always wound only to the read subvolume, even if there was write from a different client that failed on this brick. This stale read continues until there is a lookup or any write operation from the mount point. Currently, this is not a major issue, as a lookup is issued before every read and it will switch the read subvolume to a correct one. But with the plan of increasing md-cache timeout to 600s, the stale read problem will be more pronounced, i.e. stale read can continue for 600s(or more if cascaded with readdirp), as there will be no lookups. Solution: Afr doesn't have any built-in solution for stale read(without affecting the performance). The solution that came up, was to use upcall. When a file on any brick is marked bad for the first time, upcall sends a notification to all the clients that had recently accessed the file. The solution has 2 parts: - Identifying when a file is marked bad, on any of the bricks, for the first time - Client side actions on recieving the notifications Identifying when a file is marked bad on any of the bricks for the first time: ----------------------------------------------------------------------------- The idea is to track xattrop in upcall. xattrop currently comes with 2 afr xattrs - afr dirty bit and afr pending xattrs. Dirty xattr is set to 1 before every write, and is unset if write succeeds. In certain scenarios, dirty xattr can be 0 and still the file could be bad copy. Hence do not track dirty xattr. Pending xattr is set on the good copy, indicating the other bricks that have bad copy. It is still not as simple as, notifying when any of the pending xattrs change. It could lead to flood of notifcations, in case the other brick is completely down or consistantly failing. Hence it is important to notify only once, the first time a good copy is marked bad. Client side actions on recieving pending xattr change, notification: -------------------------------------------------------------------- md-cache will invalidate the cache of that file, so that further lookup is passed down to afr and hence update the read subvolume. Invalidating only in md-cache is not enough, consider the folling oder of opertaions: - pending xattr invalidation - invalidate md-cache - readdirp on the bad read subvolume - fill md-cache - lookup (served from md-cache) - read - wound to the old read subvol. Hence, along with invalidating md-cache, it is very important to reset the read subvolume for that file, in afr. Design Credit: Anuradha Talur, Ravishankar N 1. xattrop doesn't carry info saying post op/pre op. 2. Pre xattrop will have 0 value for all pending xattrs, the cbk of pre xattrop carries the on-disk xattr value. Non zero indicated healing is required. 3. Post xattrop will have non zero value for any of the pending xattrs, if the fop failed on any of the bricks.

* cluster/afr: Prevent dict_set() on NULL dictPranith Kumar K2016-10-151-1/+2
| | | | | | | | | | | | | | | | | In afr lookup when NULL dict is received in lookup, afr is supposed to set all the xattrs it requires in a new dict it creates, but for 'link-count' it is trying to set to the dict that is passed in lookup which can be NULL sometimes. This is leading to error logs. Fixed the same in this patch.

* afr: Take full locks in arbiter only for data transactionsRavishankar N2016-10-141-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: Sharding exposed a bug in arbiter config. where `dd` throughput was extremely slow. Shard xlator was sending a fxattrop to update the file size immediately after a writev. Arbiter was incorrectly over-riding the LLONGMAX-1 start offset (for metadata domain locks) for this fxattrop, causing the inodelk to be taken on the data domain. And since the preceeding writev hadn't released the lock (afr does a 'lazy' unlock if write succeeds on all bricks), this degraded to a blocking lock causing extra lock/unlock calls and delays. Fix: Modify flock.l_len and flock.l_start to take full locks only for data transactions.

* afr: Ignore gluster internal (virtual) xattrs in metadata heal checkRavishankar N2016-09-261-6/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In arbiter configuration, posix-xlator in the arbiter brick always sets the GF_CONTENT_KEY in the response dict with a value 0. If the file size on the data bricks is more than quick-read's max-file-size (64kb default), those bricks don't set the key. Because of this difference in the no. of dict elements, afr triggers metadata heal in lookup code path, in turn leading to extra lookups+inodelks. Fix: Changed afr dict comparison logic to ignore all virtual xattrs and the on-disk ones that we should not be healing. Also removed is_virtual_xattr() function. The original callers to this function (upcall) don't seem to need it anymore.

Rewrite the make rules to do what xdrgen does. Now we can get rid of xdrgen. Note 1. netbsd6's sed doesn't do -i. Why are we still running smoke tests on netbsd6 and not netbsd7? We barely support netbsd7 as it is. Note 2. Why is/was libgfxdr.so (.../rpc/xdr/src/...) linked with libglusterfs? A cut-and-paste mistake? It has no references to symbols in libglusterfs. Note3. "/#ifndef\|#define\|#endif/" (note the '\'s) is a _basic_ regex that matches the same lines as the _extended_ regex "/#(ifndef|define|endif)/". To match the extended regex sed needs to be run with -r on Linux; with -E on *BSD. However NetBSD's and FreeBSD's sed helpfully also provide -r for compatibility. Using a basic regex avoids having to use a kludge in order to run sed with the correct option on OS X. Note 4. Not copying the bit of xdrgen that inserts copyright/license boilerplate. AFAIK it's silly to pretend that machine generated files like these can be copyrighted or need license boilerplate. The XDR source files have their own copyright and license; and their copyrights are bound to be more up to date than old boilerplate inserted by a script. From what I've seen of other Open Source projects -- e.g. gcc and its C parser files generated by yacc and lex -- IIRC they don't bother to add copyright/license boilerplate to their generated files. It appears that it's a long-standing feature of make (SysV, BSD, gnu) for out-of-tree builds to helpfully pretend that the source files it can find in the VPATH "exist" as if they are in the $cwd. rpcgen doesn't work well in this situation and generates files with "bad" #include directives. E.g. if you `rpcgen ../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.x`, you get an #include directive in the generated .c file like this: ... #include "../../../../$srcdir/rpc/xdr/src/glusterfs3-xdr.h" ... which (obviously) results in compile errors on out-of-tree build because the (generated) header file doesn't exist at that location. Compared to `rpcgen ./glusterfs3-xdr.x` where you get: ... #include "glusterfs3-xdr.h" ... Which is what we need. We have to resort to some Stupid Make Tricks like the addition of various .PHONY targets to work around the VPATH "help". Warning: When doing an in-tree build, -I$(top_builddir)/rpc/xdr/... looks exactly like -I$(top_srcdir)/rpc/xdr/... Don't be fooled though. And don't delete the -I$(top_builddir)/rpc/xdr/... bits Change-Id: Iba6ab96b2d0a17c5a7e9f92233993b318858b62e BUG: 1330604 Signed-off-by: Kaleb S KEITHLEY <kkeithle@redhat.com> Reviewed-on: http://review.gluster.org/14085 Tested-by: Niels de Vos <ndevos@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: Niels de Vos <ndevos@redhat.com>

| | | | | | | | | | | | | | | | | | | | Currently, for all the update operations, metadata or data, we set the dirty flag at the end of the operation only if a brick is down. This leads to delay in healing and in some cases not at all. In this patch we set (+1) the dirty flag at the start of the metadata or data update operations and after successfull completion of the fop, we unset (-1) it again.

* dht: "replica.split-brain-status" attribute value is not correctMohit Agrawal2016-09-122-12/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In a distributed-replicate volume attribute "replica.split-brain-status" value does not display split-brain condition though directory is in split-brain. If directory is in split brain on mutiple replica-pairs it does not show full list of replica pairs. Solution: Update the dht_aggregate code to aggregate the xattr value in this specific condition. Fix: 1) function getChoices returns the choices from split-brain status string. 2) function add_opt adding the choices to local buffer to store in dictionary 3) For the key "replica.split-brain-status" function dht_aggregate call dht_aggregate_split_brain_xattr to prepare the list. Test: To verify the patch followed below steps 1) Create a distributed replica volume and create mount point 2) Stop heal daemon 3) Touch file and directories on mount point mkdir test{1..5};touch tmp{1..5} 4) Down brick process on one of the replica set pkill -9 glusterfsd 5) Change permission of dir on mount point chmod 755 test{1..5} 6) Restart brick process on node with force option 7) kill brick process on other node in same replica set 8) Change permission of dir again on mount point chmod 766 test{1..5} 9) Reexecute same step from 4-9 on other replica set also 10) After check heal status on server it will show dir's are in split brain on all replica sets 11) After check the replica.split-brain-status attr on mount point it will show wrong status of split brain. 12) After apply the patch the attribute shows correct value.

| | | | | | | | | | | | | | | | | | | | | | | | | Post add-brick event the new brick will have permission of 755 by default. If the root directory permission was other than 755, that does not get healed to the new brick leading to permission errors/inconsistencies. For choosing source of attr heal we can trust the subvols which have layouts with latest ctime(as part of missing directory heal, we heal the proper attr). In case none of the subvols have layout, return ESTALE to retrigger a fresh lookup. Note: This patch heals the permission of the root directories only. Since, permission healing of directory is not straight forward and required intrusive fix, those are not addressed here.

| | | | | | | | | | | | | | | | | | | | | | | | Problem: For healing of uid/gid we check if local->stbuf.ia_ctime is lesser than stbuf->ia_ctime (received from brick). If yes then uid/gid is updated to local->prebuf(source of healing). But we merge local->stbuf also form the newly added brick. So if we receive response from the newly added brick first and update the local->stbuf, then local->prebuf will remain empty since the newly added brick will have the latest ctime among all servers. And this can result in healing wrong uid/gids to the rest of servers. Hence, we should update local->stbuf from servers with a layout which will ignore merging stbufs from newly added bricks.

* cluster/tier: Adding compaction option for metadata databasesDiogenes Nunez2016-09-044-53/+564

As a result, tier migration slows down. To counteract this, we added a way to enable the compaction methods of the underlying database. The goal is to reduce the size of the underlying file by eliminating database fragmentation. NOTE: There is currently a bug where sometimes a brick will attempt to activate compaction. This happens even compaction is already turned on. The cause is narrowed down to the compact_mode_switch flipping its value. Changes: libglusterfs/src/gfdb - Added a gfdb function to compact the underlying database, compact_db() This is a no-op if the database has no such option. - Added a compaction function for SQLite3 that does the following 1) Changes the auto_vacuum pragma of the database 2) Compacts the database according to the type of compaction requested - Compaction type can be changed by changing the macro GF_SQL_COMPACT_DEF to one of the 4 compaction types in gfdb_sqlite3.h It is currently set to GF_SQL_COMPACT_INCR, or incremental vacuuming. xlators/cluster/dht/src - Added the following command-line option to enable SQLite3 compaction. gluster volume set <vol-name> tier-compact <off|on> - Added the following command-line option to change the frequency the hot and cold tier are ordered to compact. gluster volume set <vol-name> tier-hot-compact-frequency <int> gluster volume set <vol-name> tier-cold-compact-frequency <int> - tier daemon periodically sends the (new) GFDB_IPC_CTR_SET_COMPACT_PRAGMA IPC to the CTR xlator. The IPC triggers compaction of the database. The inputs are both gf_boolean_t. IPC Input: compact_active: Is compaction currently on for the db. compact_mode_switched: Did we flip the compaction switch recently? IPC Output: 0 if the compaction succeeds. Non-zero otherwise. xlators/features/changetimerecorder/src/ - When the CTR gets the compaction IPC, it launches a thread that will perform the compaction. The IPC ends after the thread is launched. To avoid extra allocations, the parameters are passed using static variables.

* dht, md-cache, upcall: Add invalidation of IATT when the layout changesPoornima G2016-08-301-1/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: dht_layout is built as a part of lookup only. The layout can be modified by rebalance process. Since every IO fop is preceded by a lookup, there are very less issues of stale layout. But with enhancements of aggressive caching of stats in md-cache, the lookup will reduce and expose the stale layout issue often. Solution: Since stale layout is already an issue on dht, there is already a plan to fix this at the dht layer, but this fix is not currently planned for any release. Until this fix comes out, we can have a workaround where, the upcall will send a notification to md-cache when a layout xattr is changed. As a part of layout change notification the existing cache is invalidated and the next lookup will fetch the latest layout. This is not a foolproof solution as the window between the layout change and the next lookup(after invalidation of stat), where there will be stale layout. But until the final fix comes in, this reduces the stale layout window.

* glusterd : Introduce reset brickAnuradha Talur2016-08-291-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The command basically allows replace brick with src and dst bricks as same. Usage: gluster v reset-brick <volname> <hostname:brick-path> start This command kills the brick to be reset. Once this command is run, admin can do other manual operations that they need to do, like configuring some options for the brick. Once this is done, resetting the brick can be continued with the following options. gluster v reset-brick <vname> <hostname:brick> <hostname:brick> commit {force} Does the job of resetting the brick. 'force' option should be used when the brick already contains volinfo id. Problem: On doing a disk-replacement of a brick in a replicate volume the following 2 scenarios may occur : a) there is a chance that reads are served from this replaced-disk brick, which leads to empty reads. b) potential data loss if next writes succeed only on replaced brick, and heal is done to other bricks from this one. Solution: After disk-replacement, make sure that reset-brick command is run for that brick so that pending markers are set for the brick and it is not chosen as source for reads and heal. But, as of now replace-brick for the same brick-path is not allowed. In order to fix the above mentioned problem, same brick-path replace-brick is needed. With this patch reset-brick commit {force} will be allowed even when source and destination <hostname:brickpath> are identical as long as 1) destination brick is not alive 2) source and destination brick have the same brick uuid and path. Also, the destination brick after replace-brick will use the same port as the source brick.

* cluster/afr: Give option to do consistent-ioPranith Kumar K2016-08-229-41/+229
| | | | | | | | | | | | | | | | | | | | | | | Problem: When tiering/rebalance does migrations and afr with 2-way replica is in picture, migration can read stale data if the source brick goes down and writes to the destination. After this deletion of the file leads to permanent loss of data after migration. Fix: Rebalance/tiering should migrate only when the data is definitely not stale. So introduce an option in afr called consistent-io which will be enabled in migration daemons.

* cluster/afr: Prevent split-brain when bricks are brought off and on in ↵Krutika Dhananjay2016-08-229-51/+161
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | cyclic order When the bricks are brought offline and then online in cyclic order while writes are in progress on a file, thanks to inode refresh in write txns, AFR will mostly fail the write attempt when the only good copy is offline. However, there is still a remote possibility that the file will run into split-brain if the brick that has the lone good copy goes offline *after* the inode refresh but *before* the write txn completes (I call it in-flight split-brain in the patch for ease of reference), requiring intervention from admin to resolve the split-brain before the IO can resume normally on the file. To get around this, the patch does the following things: i) retains the dirty xattrs on the file ii) avoids marking the last of the good copies as bad (or accused) in case it is the one to go down during the course of a write. iii) fails that particular write with the appropriate errno. This way, we still have one good copy left despite the split-brain situation which when it is back online, will be chosen as source to do the heal.
