* cluster/afr : set pending xattrs for replaced brickAnuradha2015-06-271-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/10448/ & http://review.gluster.org/11416 This patch is part two change to prevent data loss in a replicate volume on doing a replace-brick commit force operation. Problem: After doing replace-brick commit force, there is a chance that self heal might happen from the replaced (sink) brick rather than the source brick leading to data loss. Solution: Mark pending changelogs on afr children for the replaced afr-child so that heal is performed in the correct direction. Credits to Ravishankar N for patch 11416.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Backport of: http://review.gluster.org/10916 Because both bricks in the replica pair of patchy are in the same node, both full healer threads within the same shd try and fail to acquire non-blocking locks when each one gets lock on one of the bricks, causing heal to fail occasionally. Now heals are triggered from the mount as part of inode refresh. And because the AFR on the mount graph a. does not treat presence of dirty xattrs as something that needs a heal (this is true for dirs fool_heal and fool_me) and b. does not recursively heal the entire hierarchy of subdirs and their entries in one shot (this is true with source_creations_heal/dir1), index heal is used to heal fool_heal, fool_me and source_creations_heal/dir1 wherein only one brick (which is the brick that contains the good copy of source_creations_heal/dir_1: brick-1) has all the gfids to be healed copied into its indices/xattrop directory.

* ctr/xlator: Named lookup heal of pre-existing files, before ctr was ON.Joseph Fernandes2015-05-081-0/+72
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* Tests: use a portable way to flush kernel cacheEmmanuel Dreyfus2015-05-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

If the volume is already started, a brick process is already there and the restart will fail, as the brick TCP port is already in use. Because the new brick process is not started, the volume is left with no brick online, and the volume stop operation will timeout waiting for bricks to stop. Obviosuly we have two bugs here - If volume reset network.compression needs to restart the bricks, it should first make sure the previous brick process is terminated - volume stop should not wait forever for bricks to come back online This change does not fix the bugs but just makes sure the volume is stoped before volume reset network.compression, so that the failure oes not happen. backport of: I9cd5cdc767ef6ee9dd31f2121d672dc3bfdce45f BUG: 1212676 Change-Id: If85c46f7ed675c4c84cc4170292b1f0f41e5b456 Signed-off-by: Emmanuel Dreyfus <manu@netbsd.org> Reviewed-on: http://review.gluster.org/10587 Tested-by: Gluster Build System <jenkins@build.gluster.com> Tested-by: NetBSD Build System Reviewed-by: Vijay Bellur <vbellur@redhat.com>

* libxlator: Change marker xattr handling interfacePranith Kumar K2015-03-251-0/+108
| | | | | | | | | | | | | | | | | | | | | - Changed the implementation of marker xattr handling to take just a function which populates important data that is different from default 'gauge' values and subvolumes where the call needs to be wound. - Removed duplicate code I found while reading the code and moved it to cluster_marker_unwind. Removed unused structure members. - Changed dht/afr/stripe implementations to follow the new implementation - Implemented marker xattr handling for ec.

* cluster/dht: Add tier translator.Dan Lambright2015-03-211-0/+116
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The tier translator shares most of DHT's code. It differs in how subvolumes are chosen for I/Os, and how file migration (cache promotion and demotion) is managed. That different functionality is split to either DHT or tier logic according to the "tier_methods" structure. A cache promotion and demotion thread is created in a manner similar to the rebalance daemon. The thread operates a timing wheel which periodically checks for promotion and demotion candidates (files). Candidates are queued and then migrated. Candidates must exist on the same node as the daemon and meet other critera per caching policies. This patch has two authors (Dan Lambright and Joseph Fernandes). Dan did the DHT changes and Joe wrote the cache policies. The fix depends on DHT readidr changes and the database library which have been submitted separately. Header files in libglusterfs/src/gfdb should be reviewed in patch 9683. For more background and design see the feature page [1].
