Fix: remove condition checking which is always resulting in false, and removing if block which is always unreachable.

* glusterd: fix brick restart parallelismAtin Mukherjee2017-11-016-32/+87
| | | | | | | | | | | | | | | | | | | | | | | | | | glusterd's brick restart logic is not always sequential as there is atleast three different ways how the bricks are restarted. 1. through friend-sm and glusterd_spawn_daemons () 2. through friend-sm and handling volume quorum action 3. through friend handshaking when there is a mimatch on quorum on friend import. In a brick multiplexing setup, glusterd ended up trying to spawn the same brick process couple of times as almost in fraction of milliseconds two threads hit glusterd_brick_start () because of which glusterd didn't have any choice of rejecting any one of them as for both the case brick start criteria met. As a solution, it'd be better to control this madness by two different flags, one is a boolean called start_triggered which indicates a brick start has been triggered and it continues to be true till a brick dies or killed, the second is a mutex lock to ensure for a particular brick we don't end up getting into glusterd_brick_start () more than once at same point of time.

* glusterd: clean up portmap on brick disconnectAtin Mukherjee2017-10-314-11/+46
| | | | | | | | | | | | | | | | | | | | GlusterD's portmap entry for a brick is cleaned up when a PMAP_SIGNOUT event is initiated by the brick process at the shutdown. But if the brick process crashes or gets killed through SIGKILL then this event is not initiated and glusterd ends up with a stale port. Since GlusterD's portmap traversal happens both ways, forward for allocation and backward for registry search, there is a possibility that glusterd might end up running with a stale port for a brick which eventually will end up with clients to fail to connect to the bricks. Solution is to clean up the port entry in case the process is down as part of the brick disconnect event. Although with this the handling PMAP_SIGNOUT event becomes redundant in most of the cases, but this is the safeguard method to avoid glusterd getting into the stale port issues.

* glusterd: persist brickinfo's port change into glusterd's storeGaurav Yadav2017-10-315-10/+62
| | | | | | | | | | | | | | | | | | Problem: Consider a case where node reboot is performed and prior to reboot brick was listening to 49153. Post reboot glusterd assigned 49152 to brick and started the brick process but the new port was never persisted. Now when glusterd restarts glusterd always read the port from its persisted store i.e 49153 however pmap signin happens with the correct port i.e 49152. Fix: Make sure when glusterd_brick_start is called, glusterd_store_volinfo is eventually invoked.

But the timeout was not honored and was able to access the file even after the timeout. Fix: Call the inode_invalidate() in afr_set_split_brain_choice_cbk() so that it will triger the cache invalidate after resetting the timer and the split brain choice. So the next calls to access the file will fail with EIO. Change-Id: I698cb833676b22ff3e4c6daf8b883a0958f51a64 BUG: 1503519 Signed-off-by: karthik-us <ksubrahm@redhat.com>
* posix: Ignore disk space reserve check for internal FOPSMohit Agrawal2017-10-305-36/+36
| | | | | | | | | | | | | Problem: Currently disk space reserve check is applicable for internal FOP also it needs to be ignore for internal FOP. Solution: Update the DISK_SPACE_CHECK_AND_GOTO macro at posix component. Macro will call only while key "GLUSTERFS_INTERNAL_FOP_KEY" exists in xdata.

* md-cache: Add additional samba and macOS specific EAs to mdcacheGünther Deschner2017-10-301-6/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Samba ships with a server implementation of the Apple Create Context extension (AAPL) as negotiated by all modern Apple clients. With the support of the AAPL extension, Apple clients will integrate better with Samba servers. The AAPL implementation itself is contained in the Samba vfs_fruit(8) module which has to be activated in Samba. This vfs_fruit module also provides support for macOS alternate data streams which will be represented in EAs. Two standard data streams ("AFP_AfpInfo" and "AFP_Resource") will be stored in the following EAs: * user.org.netatalk.Metadata * user.org.netatalk.ResourceFork For all other data streams, vfs_fruit relies on another Samba vfs module, vfs_streams_xattr(8), to handle these. Although configurable, by default the vfs_streams_xattr module will build EA keynames with a "user.DosStream." prefix. Please note that we have to deal with only one known prefix key, as macOS will happily compose EA keynames like: * user.DosStream.com.apple.diskimages.fsck:$DATA * user.DosStream.com.apple.diskimages.recentcksum:$DATA * user.DosStream.com.apple.metadata:kMDItemWhereFroms:$DATA * user.DosStream.com.apple.quarantine:$DATA * etc. Caching of vfs_fruit specific EAs is crucial for SMB performance and is controlled with the same configuration option "performance.cache-samba-metadata".

* cluster/afr: Fail open on split-brainPranith Kumar K2017-10-2611-95/+208
| | | | | | | | | | | | | | | | | Problem: Append on a file with split-brain succeeds. Open is intercepted by open-behind, when write comes on the file, open-behind does open+write. Open succeeds because afr doesn't fail it. Then write succeeds because write-behind intercepts it. Flush is also intercepted by write-behind, so the application never gets to know that the write failed. Fix: Fail open on split-brain, so that when open-behind does open+write open fails which leads to write failure. Application will know about this failure.

* Make sure attach_brick return a proper error codeMichael Scherer2017-10-261-1/+1
| | | | | | | | | | | | | | Coverity warn about "Using uninitialized value "ret".", which is indeed the case. If we can't attach after 15 tries, attach_brick return uninitiliazed return code, which is likely hard to trigger, but bad. I use -1 to follow the UNIX convetion, but there is no specific error code tested by code.

| | | | | | | | | | | | | without the fix, the stat entry on a file would return inode==1 for many files, in case of subdir mount This happened with the confusion of return value of 'gf_uuid_compare()', it is more like strcmp, instead of a gf_boolean return value, and hence resulted in the bug.
