* cluster/dht: pass a destination subvol to fop2 variants to avoid races.Raghavendra G2015-06-021-0/+0
| | | | | | | | | | | | | | | | | | | The destination subvol used in the fop2 variants is either stored in inode-ctx1 or local->cached_subvol. However, it is not guaranteed that a value stored in these locations before invocation of fop2 is still present after the invocation as these locations are shared among different concurrent operations. So, to preserve the atomicity of "check dst-subvol and invoke fop2 variant if dst-subvol found", we pass down the dst-subvol to fop2 variant. This patch also fixes error handling in some fop2 variants.

* dht: Add lookup-optimize configuration option for DHTShyam2015-06-021-1/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently with commit 4eaaf5 a mixed version cluster would have issues if lookup-uhashed is set to auto, as older clients would fail to validate the layouts if newer clients (i.e 3.7 or upwards) create directories. Also, in a mixed version cluster rebalance daemon would set commit hash for some subvolumes and not for the others. This commit fixes this problem by moving the enabling of the functionality introduced in the above mentioned commit to a new dht option. This option also has a op_version of 3_7_1 thereby preventing it from being set in a mixed version cluster. It brings in the following changes, - Option can be set only if min version of the cluster is 3.7.1 or more - Rebalance and mkdir update the layout with the commit hashes only if this option is set, hence ensuring rebalance works in a mixed version cluster, and also directories created by newer clients do not cause layout errors when read by older clients - This option also supersedes lookup-unhased, to enable the optimization for lookups more deterministic and not conflict with lookup-unhashed settings. Option added is cluster.lookup-optimize, which is a boolean. Usage: # gluster volume set VOLNAME cluster.lookup-optimize on Change-Id: Ifd1d4ce3f6438fcbcd60ffbfdbfb647355ea1ae0 BUG: 1222126 Signed-off-by: Shyam <srangana@redhat.com> Reviewed-on: http://review.gluster.org/10797 Tested-by: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Kaushal M <kaushal@redhat.com> Reviewed-by: Raghavendra G <rgowdapp@redhat.com> Tested-by: Raghavendra G <rgowdapp@redhat.com>

* dht: make lookup-unhashed=auto do something actually usefulJeff Darcy2015-05-104-12/+116
| | | | | | | | | | | | | | | | | | | | | | | | The key concept here is to determine whether a directory is "clean" by comparing its last-known-good topology to the current one for the volume. These are stored as "commit hashes" on the directory and the volume root respectively. The volume's commit hash changes whenever a brick is added or removed, and a fix-layout is done. A directory's commit hash changes only when a full rebalance (not just fix-layout) is done on it. If all bricks are present and have a directory commit hash that matches the volume commit hash, then we can assume that every file is in its "proper" place. Therefore, if we look for a file in that proper place and don't find it, we can assume it's not on any other subvolume and *safely* skip the global (broadcast to all) lookup.

* features/bit-rot-stub: versioning of objects in write/truncate fop instead ↵Raghavendra Bhat2015-05-082-14/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of open * This patch brings in the changes where object versioning is done in write and truncate fops instead of tracking them in open and create fops. This model works for both regular and anonymous fds. It also removes the race associated with open calls, create and lookups. This patch follows the below method for object versioning and notifications: Before sending writev on the fd, increase the ongoing version first. This makes anonymous fd write similar to the regular fd write by having the ongoing version increased before doing the write. Do following steps to do versioning: 1) For anonymous fds set the fd context (so that release is invoked) and add the fd context to the list maintained in the inode context. For regular fds the above think would have been done in open itself. 2) Increase the on-disk ongoing version 3) Increase the in memory ongoing version and mark inode as non-dirty 3) Once versioning is successfully done send write operation. If versioning fails, then fail the write fop. 5) In writev_cbk mark inode as modified.

* 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.

* ctr/xlator: Named lookup heal of pre-existing files, before ctr was ON.Joseph Fernandes2015-05-061-0/+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.

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.
