* features/index: Delete granular entry indices of already healed directories ↵Krutika Dhananjay2016-11-241-2/+21
| | | | | | | | | | | | | | | | | | | | | | during crawl If granular name indices are already in existence for a volume, and before they are healed, granular entry heal be disabled, a crawl on indices/xattrop will clear the changelogs on these directories. When their corresponding entry-changes indices are crawled subsequently, if it is found that the directories don't need heal anymore, the granular indices are not cleaned up. This patch fixes that problem by ensuring that the zero-xattrop also deletes the stale indices at the level of index translator.

* marker: Fix inode value in loc, in setxattr fopPoornima G2016-11-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | On recieving a rename fop, marker_rename() stores the, oldloc and newloc in its 'local' struct, once the rename is done, the xtime marker(last updated time) is set on the file, but sending a setxattr fop. When upcall receives the setxattr fop, the loc->inode is NULL and it crashes. The loc->inode can be NULL only in one valid case, i.e. in rename case where the inode of new loc can be NULL. Hence, marker should have filled the inode of the new_loc before issuing a setxattr.

* md-cache, afr: Reduce the window of stale readPoornima G2016-10-203-114/+283
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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.

* feature/bitrot: Fix recovery of corrupted hardlinkKotresh HR2016-09-081-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: When a file with hardlink is corrupted in ec volume, the recovery steps mentioned was not working. Only name and metadata was healing but not the data. Cause: The bad file marker in the inode context is not removed. Hence when self heal tries to open the file for data healing, it fails with EIO. Background: The bitrot deletes inode context during forget. Briefly, the recovery steps involves following steps. 1. Delete the entry marked with bad file xattr from backend. Delete all the hardlinks including .glusters hardlink as well. 2. Access the each hardlink of the file including original from the mount. The step 2 will send lookup to the brick where the files are deleted from backend and returns with ENOENT. On ENOENT, server xlator forgets the inode if there are no dentries associated with it. But in case hardlinks, the forget won't be called as dentries (other hardlink files) are associated with the inode. Hence bitrot stube won't delete it's context failing the data self heal. Fix: Bitrot-stub should delete the inode context on getting ENOENT during lookup.

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.

* md-cache: Register the list of xattrs with cache-invalidationPoornima G2016-08-303-10/+125
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: md-cache caches a specified list of xattrs, and when cache invalidation is enabled, it makes sense to recieve invalidation only when those xattrs are modified by other clients. But the current implementation of upcall is that, it will send invalidation when any of the on-disk xattrs is modified. Solution: md-cache sends a list of xattrs that it is interested in, to upcall by issuing an ipc(). The challenge here is to make sure everytime a brick goes offline and comes back up, the ipc() needs to be issued to the bricks. Hence ipc() is sent from md-cache every time there is a CHILD_UP/CHILD_MODIFIED event. TODO: There will be patches following, in cluster xlators, to implement ipc fop.

Well, it was not a necessity to free rpc-clnt object till now because all the existing use cases needs to reconnect back on disconnects. Hence timer code was not taking ref on rpc-clnt object. Glusterd had some use-cases that led to crash due to ping-timer and they fixed only those code paths that involve ping-timer. Now, since changelog has an use-case where rpc-clnt need to be freed up, we need to fix timer code to take refs 2. In changelog, because of issue 1, only mydata was being freed which is incorrect. And there are races where rpc-clnt object would access the freed mydata which would lead to crashes. Since changelog xlator resides on brick side and is long living process, if multiple libgfchangelog consumers register to changelog and disconnect/reconnect mulitple times, it would result in leak of 'rpc-clnt' object for every connect/disconnect. SOLUTION: 1. Handle ref/unref of 'rpc_clnt' structure in timer functions properly. 2. In changelog, unref 'rpc_clnt' in RPC_CLNT_DISCONNECT after disabling timers and free mydata on RPC_CLNT_DESTROY. RPC SETUP IN CHANGELOG: 1. changelog xlator initiates rpc server say 'changelog_rpc_server' 2. libgfchangelog initiates one rpc server say 'libgfchangelog_rpc_server' 3. libgfchangelog initiates rpc client and connects to 'changelog_rpc_server' 4. In return changelog_rpc_server initiates a rpc client and connects back to 'libgfchangelog_rpc_server' REF/UNREF HANDLING IN TIMER FUNCTIONS: Let's say rpc clnt refcount = 1 1. Take the ref before reigstering callback to timer queue >>>> rpc_clnt_ref (say ref count becomes = 2) 2. Register a callback to timer say 'callback1' 3. If register fails: >>>> rpc_clnt_unref (ref count = 1) 4. On timer expiration, 'callback1' gets called. So unref rpc clnt at the end in 'callback1'. This is corresponding to ref taken in step 1 >>>> rpc_clnt_unref (ref count = 1) 5. The cycle from step-1 to step-4 continues....until timer cancel event happens 6. timer cancel of say 'callback1' If timer cancel fails: Do nothing, Step-4 would have unrefd If timer cancel succeeds: >>>> rpc_clnt_unref (ref count = 1) Change-Id: I91389bc511b8b1a17824941970ee8d2c29a74a09 BUG: 1316178 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/13658 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>

| | | | | | | | | | | | | | | | | | In the notify function in trash xlator, a lookup is performed to obtain path of old trash directory. The result usually contains path without '/' at the end. The trash xlator maintains expects '/' at the end for the values such as 'old trash dir' and 'new trash dir'. Otherwise certian checks in the code will fail.
