* rpc: Reduce frame-timeout for glusterd connectionsKaushal M2012-08-173-8/+46
| | | | | | | | | | | | | | | | Reduce frame-timeout for glusterd connections from 30mins to 10 mins. 30mins is too long when compared to cli timeout of 2mins. Changing to 10mins reduces the disparity between cli and glusterd. Also, fix glusterfs_submit_reply() so that a reply is sent even if serialize failed.

* cluster/afr: Handle child_up & fd not opened case in xactionPranith Kumar K2012-08-171-7/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: When an fd is opened while a brick is down, after the brick comes back up afr issues open on the other brick. It can fail for a number of reasons (enoent etc). While the system is in that state, inode/entrylks pre-op happen only on the brick that is up and fd is opened for fd-fops. post-op should consider only the bricks where both pre-op and fop succeeded as success, rest of them as failures. Code now marks only the children that are down as failures as opposed to child_down & fd-not-opened. This makes change-log appear as success on the subvolume where we did not do any fop leading to no change-log but differences in data/metadata for reg-files. Fix: Mark non-participants of fop as failure. This is tracked in transaction.pre_op[]. Tests: Simulated the scenario using err-gen on top of one of the client xlator which fails all fops always. Performed fops and the changelog represented pending fops on the brick with err-gen loaded. Tested the case of brick down and perform entry/metadata/data operations to confirm they still work as expected.

* cluster/afr: Avoid setting split-brain outside inode locksPranith Kumar K2012-08-135-34/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | RCA: The bug is observed because the decision to mark a file in split-brain is taken outside appropriate locks. Lookup gathers xattrs outside any lock. The xattrs being in split-brain in lookup should only be taken as a hint. Appropriate inodelks should be taken before confirming a split-brain. Self-heal confirms this at the moment. Fix: Self-heals are launched to inspect xattrs when the data/metadata self-heal options are turned on. Decision to set/reset split-brain flag is taken inside appropriate locks. Known Issue After fix: If data/metadata self-heal is turned off, inspecting of xattrs could not be performed so split-brain behavior does not work correctly if the self-heal options are turned off. This bug is handled only in upstream.

This affects other fops with conflicting inode, entry locks with self-heal. Fix: This patch provides configuring enable/disable of least-priority.

| | | | | | | | | | | | | | | | | | | | | | | A crash occurs when attempting to link a named pipe on a striped, replicated volume. The cause for this crash is attempting to deref a NULL inode pointer in stripe_link_cbk(). The RCA for this bug uncovered a couple of problems: - AFR ignores the inode pointer it receives on failure (returning NULL). - stripe assumes the inode pointer is valid on failure. Either one of these changes addresses the crash, but this patch includes both changes. AFR is modified to pass along the inode pointer it receives (which could still be NULL). stripe is modified to not assume the inode pointer is valid on fop failure.

* Fixes for gsyncd / geo-rep and FUSE listxattrVenky Shankar2012-07-242-8/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes two problems with recent changes to Geo-Replication First: ------ Recent changes to geo-replication relies on Rsync to tranfer extended attributes. Essentially Rsync would invoke a listxattr() and then getxattr() the set reutrned by listxattr() and finally transfer it to the remote slave. Xattrs like security.selinux would create problems as they are not allowed to be set explicitly (unless there's a rule that allows this). So, to make Rsync behave sanely we filter out all "*.selinux*" xattrs from listxattr() (which is getxattr() with ->name as NULL). Second: ------- Python's "if {..} else {..}" shortcut ".. and .. or .." was misused here. This is a straightforward fix by interchanging last two variables (classes in this case). Also fix a typo in sendmark_regular() definition.

* FUSE: ignore setxattr for some keys from gsyncd aux mountVenky Shankar2012-07-193-0/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | Context ------- gsyncd/geo-rep plans to rely on Rsync to sync extended attributes. When this is in place, all xattrs *visible* on the mount point would be candidate for syncing. This set could include gluster internal xattrs too (as xome xlators do not filter out in their cbks). Syncing these xattrs to the slave could result in unexpected functioning of the slave mount. Soln. ----- For gsyncd auxillary mounts (identified by client_pid -1), we only allow xtime related xattrs to go through and silently ignore (w/o propagating error back to the client) the rest of them. This provides a future proof solution as we need not worry about what xattrs show up on the mounts. Also, 'user' namespace xattrs are always passed through even if it's from a gsyncd aux mount.

The elimination of holes in striped files eliminates space wasted via local filesystem preallocation heuristics and significantly improves read performance. Coalesce mode is implemented with a new 'coalesce' xlator option, which is user-configurable and disabled by default. The format of newly created files is marked with a new 'stripe-coalesce' xattr. Cluster/stripe handles/preserves the format of files regardless of the current mode of operation (i.e., a volume can simultaneously consist of coalesced and non-coalesced files). Files without the stripe-coalesce attribute are assumed to have the traditional format to provide backward compatibility. extras/stripe-merge: support traditional and coalesce stripe formats Update the stripe-merge recovery tool to handle the traditional and coalesced file formats.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit is based on Venky Shankar <vshankar@>'s original implementation. Let us first quote Venky's description, then we summarize changes to his work. ------ First version of failover/failback. Failback mechanism uses two exclusive modes: * blind-sync This mode works with xtime pairs (both master and slave) to identify candidated to sync the original master from the slave * wrapup-sync This mode is similar to the normal working of gsyncd except that orphaned entities in the gluster volume are not assigned xtimes. This prevents un-necessary transfer of data for such entities. Modes can be enabled via: gluster volume geo-replication M S config special_sync_mode blind gluster volume geo-replication M S config special_sync_mode wrapup To turn off the special modes (i.e. to revert to normal gsyncd behaviour) use: gluster volume geo-replication colon-d0 192.168.1.2::colon-d config \!special_sync_mode ------ Code has been refactored to meet following goals: - make checkpointing work with special sync modes - move out sync mode related conditionals from the crawl loop and make all decisions to be made at startup time - be intrusive to the crawl loop to smallest possible degree (we will have to change/revisit it for other reasons, and the complexity of that should not increase) So, xtime parsing/updating/evaluation that's specific to the certain special modes are represented as mixin classes; basic operation logic is in an abstract base class. On startup, special-sync-mode tunable is dynamically dispatched to the corresponding mixin and the actual master class is derived from the chosen mixin and the ABS.

(Technically, gsyncd makes a note of the xtime of master's root as of setting the checkpoint, called the "checkpoint target".) - gluster vol geo-rep M S conf \!checkpoint deletes the checkpoint. - gluster vol geo-rep M S stat if status is OK, and there is a checkpoint configured, the checkpoint info is appended to status (either "not yet reached", or "completed at <timestamp of completion>"). (Technically, the worker runs a thread that monitors / serializes / verifies checkpoint status, and answers checkpoint status requests through a UNIX socket; monitoring boils down to querying the xtime of slave's root and comparing with the target.) - gluster vol geo-rep M S conf log-file | xargs grep checkpoint displays the checkpoint history. Set, delete and completion events are logged properly. Change-Id: I4398e0819f1504e6e496b4209e91a0e156e1a0f8 BUG: 826512 Signed-off-by: Csaba Henk <csaba@redhat.com>

* geo-rep / gsyncd: fix cleanup of temporary mountsCsaba Henk2012-06-101-17/+76
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [This is a "forward port" of fafd5c17, http://review.gluster.com/2908] The "finally" clause that was meant to cleanup after the temp mount has not covered the case of getting signalled (eg. by monitor, upon worker timing out). So here we "outsource" the cleanup to an ephemeral child process. Child calls setsid(2) so it won't be bothered by internal process management. We use a pipe in between worker and the cleanup child; when child sees the worker end getting closed, it performs the cleanup. Worker end can get closed either because worker closes it (normal case), or because worker has terminated (faulty case) -- thus as bonus, we get a nice uniform handling with no need to differentiate between normal and faulty cases. The faulty case that was seen IRL -- ie., users of maintainance mounts hang in chdir(2) to mount point -- can be simulated for testing purposes by applying the following patch: diff --git a/xlators/mount/fuse/src/fuse-bridge.c b/xlators/mount/fuse/src/fuse-bridge.c index acd3c68..1ce5dc1 100644 --- a/xlators/mount/fuse/src/fuse-bridge.c +++ b/xlators/mount/fuse/src/fuse-bridge.c @@ -2918,7 +2918,7 @@ fuse_init (xlator_t *this, fuse_in_header_t *finh, void *msg) if (fini->minor < 9) *priv->msg0_len_p = sizeof(*finh) + FUSE_COMPAT_WRITE_IN_SIZE; #endif - ret = send_fuse_obj (this, finh, &fino); + ret = priv->client_pid_set ? 0 : send_fuse_obj (this, finh, &fino); if (ret == 0) gf_log ("glusterfs-fuse", GF_LOG_INFO, "FUSE inited with protocol versions:" Change-Id: I14bad56a60a7fa82d0104fa4b9a20f4e42a7186f BUG: 786291 Signed-off-by: Csaba Henk <csaba@redhat.com> Reviewed-on: http://review.gluster.com/3542 Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Vijay Bellur <vijay@gluster.com>
