* build: add --without-server optionNiels de Vos2018-02-211-0/+5
| | | | | | | | | | | | | | | | With Gluster 4.0 we will not provide the server components for EL6 and older. At one point Gluster 4.x will get GlusterD2, which requires Golang tools in the distribution. EL6 does not contain these at the moment. With this change, it is possible to `./configure --without-server` which prevents building glusterd and the xlators for the bricks. Building RPMs can pass `--without server` and the glusterfs-server sub-package will not be created.

* glusterd: import volumes in separate synctaskAtin Mukherjee2018-02-216-70/+343
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With brick multiplexing, to attach a brick to an existing brick process the prerequisite is to have the compatible brick to finish it's initialization and portmap sign in and hence the thread might have to go to a sleep and context switch the synctask to allow the brick process to communicate with glusterd. In normal code path, this works fine as glusterd_restart_bricks () is launched through a separate synctask. In case there's a mismatch of the volume when glusterd restarts, glusterd_import_friend_volume is invoked and then it tries to call glusterd_start_bricks () from the main thread which eventually may land into the similar situation. Now since this is not done through a separate synctask, the 1st brick will never be able to get its turn to finish all of its handshaking and as a consequence to it, all the bricks will fail to get attached to it. Solution : Execute import volume and glusterd restart bricks in separate synctask. Importing snaps had to be also done through synctask as there's a dependency of the parent volume need to be available for the importing snap functionality to work. >mainline patch : https://review.gluster.org/#/c/19357/ https://review.gluster.org/#/c/19536/ https://review.gluster.org/#/c/19539/ Change-Id: I290b244d456afcc9b913ab30be4af040d340428c BUG: 1543706 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit cb0339f9229fc5c05d7ef4cfcc4ca9c4569f3755)

* glusterd: process pmap sign in only when port is marked as freeAtin Mukherjee2018-02-091-0/+15
| | | | | | | | | | | | | | | | | | | Because of some crazy race in volume start code path because of friend handshaking with volumes with quorum enabled we might end up into a situation where glusterd would start a brick and get a disconnect and then immediately try to start the same brick instance based on another friend update request. And then if for the very first brick even if the process doesn't come up at the end sign in event gets sent and we end up having two duplicate portmap entries for the same brick. Since in brick start we mark the previous port as free, its better to consider a sign in request as no op if the corresponding port type is marked as free. >mainline patch : https://review.gluster.org/#/c/19263/ Change-Id: I995c348c7b6988956d24b06bf3f09ab64280fc32 BUG: 1543711 Signed-off-by: Atin Mukherjee <amukherj@redhat.com> (cherry picked from commit 9d708a3739c8201d23f996c413d6b08f8b13dd90)

* cluster/dht: avoid overwriting client writes during migrationSusant Palai2018-02-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | For more details on this issue see https://github.com/gluster/glusterfs/issues/308 Solution: This is a restrictive solution where a file will not be migrated if a client writes to it during the migration. This does not check if the writes from the rebalance and the client actually do overlap. If dht_writev_cbk finds that the file is being migrated (PHASE1) it will set an xattr on the destination file indicating the file was updated by a non-rebalance client. Rebalance checks if any other client has written to the dst file and aborts the file migration if it finds the xattr. updates gluster/glusterfs#308 Change-Id: I73aec28bc9dbb8da57c7425ec88c6b6af0fbc9dd Signed-off-by: Susant Palai <spalai@redhat.com> Signed-off-by: Raghavendra G <rgowdapp@redhat.com> Signed-off-by: N Balachandran <nbalacha@redhat.com> (cherry picked from commit 545a7ce6762a1b3a7b989b43a9d18b5b1b299df0)

* dentry fop serializer: added new server side xlator for dentry fop serializationSakshi Bansal2018-01-302-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problems addressed by this xlator : [1]. To prevent race between parallel mkdir,mkdir and lookup etc. Fops like mkdir/create, lookup, rename, unlink, link that happen on a particular dentry must be serialized to ensure atomicity. Another possible case can be a fresh lookup to find existance of a path whose gfid is not set yet. Further, storage/posix employs a ctime based heuristic 'is_fresh_file' (interval time is less than 1 second of current time) to check fresh-ness of file. With serialization of these two fops (lookup & mkdir), we eliminate the race altogether. [2]. Staleness of dentries This causes exponential increase in traversal time for any inode in the subtree of the directory pointed by stale dentry. Cause : Stale dentry is created because of following two operations: a. dentry creation due to inode_link, done during operations like lookup, mkdir, create, mknod, symlink, create and b. dentry unlinking due to various operations like rmdir, rename, unlink. The reason is __inode_link uses __is_dentry_cyclic, which explores all possible path to avoid cyclic link formation during inode linkage. __is_dentry_cyclic explores stale-dentry(ies) and its all ancestors which is increases traversing time exponentially. Implementation : To acheive this all fops on dentry must take entry locks before they proceed, once they have acquired locks, they perform the fop and then release the lock.

* cluster/afr: Adding option to take full file lockkarthik-us2018-01-191-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: In replica 3 volumes there is a possibilities of ending up in split brain scenario, when multiple clients writing data on the same file at non overlapping regions in parallel. Scenario: - Initially all the copies are good and all the clients gets the value of data readables as all good. - Client C0 performs write W1 which fails on brick B0 and succeeds on other two bricks. - C1 performs write W2 which fails on B1 and succeeds on other two bricks. - C2 performs write W3 which fails on B2 and succeeds on other two bricks. - All the 3 writes above happen in parallel and fall on different ranges so afr takes granular locks and all the writes are performed in parallel. Since each client had data-readables as good, it does not see file going into split-brain in the in_flight_split_brain check, hence performs the post-op marking the pending xattrs. Now all the bricks are being blamed by each other, ending up in split-brain. Fix: Have an option to take either full lock or range lock on files while doing data transactions, to prevent the possibility of ending up in split brains. With this change, by default the files will take full lock while doing IO. If you want to make use of the old range lock change the value of "cluster.full-lock" to "no".

This is only a notification that can be used to improve performance of some client side operations that might benefit from extended duration of lock ownership. Nothing is done if the lock owner decides to ignore the message and to not release the lock. For forced release of acquired resources, leases must be used.

* glusterd: fix up volume option flagsCsaba Henk2018-01-071-3/+3
| | | | | | | | | | | | | | | | | | | | | | In glusterd volfile generation code options should be ornamented with the VOLOPT_FLAG_* flags. However, some are ornamented with OPT_FLAG_* flags (which are to be used in xlator context). The impact is: the OPT_FLAG_* that occurs is OPT_FLAG_CLIENT_OPT, which has the same value as VOLOPT_FLAG_XLATOR_OPT, so what was meant is "option affects clients" and what was there means "option enables/disables xlators". Because of this semantic shift, op version might be incorrectly calculated for volumes and clients. (At this point it's a theoretical possibility. Actual occurrence might depend on connecting client & server versions; it's also possible that there exists a proof of concept scenario but it's irrealistic.) This commit eliminates the OPT_FLAG_* occurrences from glusterd code, and replaces them with the appropriate VOLOPT_FLAG_* flags.

* Tier: Stop tierd for detach starthari gowtham2017-12-017-173/+158
| | | | | | | | | | | | | | | | | | | Problem: tierd was stopped only after detach commit This makes the detach take a longer time. The detach demotes the files to the cold brick and if the promotion frequency is hit, then the tierd starts to promote files to hot tier again. Fix: stop tierd after detach start so the files get demoted faster. Note: the is_tier_enabled was not maintained properly. That has been fixed too. some code clean up has been done.

Create a new file and wait for the retention time to expire. 4. After retention time expires, do an truncate, rename, unlink, link or write to send the file in Worm state. 5. After that do `rm -f filename`. 6. The file is successfully removed. 7. Repeat from step 2 by setting features.worm-files-deletable 0. This time deletion should not be successful.
