* Fix invalid seekdir() usagev3.6.0beta3Emmanuel Dreyfus2014-09-303-3/+103
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to POSIX, seekdir() should only be given offset obtained from telldir() on the same DIR * http://pubs.opengroup.org/onlinepubs/9699919799/functions/seekdir.html Code from afr-self-heald.c and index.c is operating outside of the specification, by doing using seekdir() with offset from a previously open/close/re-open directory. This seems to work on Linux (although with no guarantee it will always in the future). On NetBSD the seekdir() with a in invalid offset is a nilpotent operation, and causes an infinite loop, since index_fill_readdir() always restart from the beginning of the directory. The situation is fixed by using a non anonymous fd in afr-self-heald.c: we explicitely open the directory so that it remains open on the brick side during the timeframe where we want to reuse offsets in seekdir(). This requires adding an opendir fop in index xlator. If the brick was not updated, the opendir will fail and we fallback to the standard violating approach for backward compatibility on Linux. On other systems we fail since it never worked. While there, add tests to check seekdir() success in index and posix xlators, so that incorrect usage from calling code produce an explicit error instead of an infinite loop. We can only do it on non Linux systems, for the sake of backward compatibility when the brick was updated but not the client.

* glusterd/quota: Heal pgfid xattr on existing data when the quota is enablevmallika2014-09-304-3/+74
| | | | | | | | | | | | | | | | | | | | | This is a backport of http://review.gluster.org/#/c/8878/ The pgfid extended attributes are used to construct the ancestry path (from the file to the volume root) for nameless lookups on files. As NFS relies on nameless lookups heavily, quota enforcement through NFS would be inconsistent if quota were to be enabled on a volume with existing data. Solution is to heal the pgfid extended attributes as a part of lookup perfomed by quota-crawl process. In a posix lookup check for pgfid xattr and if it is missing set the xattr.

* geo-rep: Fix rename of directory syncing.Kotresh HR2014-09-291-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The rename of directories are captured in all distributed brick changelogs. gsyncd processess these changelogs on each brick parallellaly. The first changelog to get processed will be successful. All subsequent ones will stat the 'src' and if not present, tries to create freshly on slave. It should be done only for files and not for directories. Hence when this code path was hit, regular file's blob is sent as directory's blob and gfid-access translator was erroring out as 'Invalid blob length' with errno as 'ENOMEM' Change-Id: I50545b02b98846464876795159d2446340155c82 BUG: 1147422 Signed-off-by: Kotresh HR <khiremat@redhat.com> Reviewed-on: http://review.gluster.org/8865 Reviewed-by: Aravinda VK <avishwan@redhat.com> Tested-by: Gluster Build System <jenkins@build.gluster.com> Reviewed-by: Venky Shankar <vshankar@redhat.com> Tested-by: Venky Shankar <vshankar@redhat.com> Reviewed-on: http://review.gluster.org/8880 Reviewed-by: Vijay Bellur <vbellur@redhat.com>
* geo-rep: fix same file different gfid in master and slaveAravinda VK2014-09-292-17/+38
| | | | | | | | | | | | | | | | | | | | | | | While processing RENAME in changelog, if the file is unlinked in master, then geo-rep was sending UNLINK to slave instead of RENAME. If rsync job fails if one of the file failed to sync in the job. This patch adds logic to remove GFID from data list if the same changelog has UNLINK entry for it after the DATA. Or it removes those GFIDs during retry of changelogs processing.

* cluster/afr: Launch self-heal only when all the brick status is knownPranith Kumar K2014-09-291-2/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: File goes into split-brain because of wrong erasing of xattrs. RCA: The issue happens because index self-heal is triggered even before all the bricks are up. So what ends up happening while erasing the xattrs is, xattrs are erased only on the sink brick for the brick that it thinks is up leading to split-brain Example: lets say the xattrs before heal started are: brick 2: trusted.afr.vol1-client-2=0x000000020000000000000000 trusted.afr.vol1-client-3=0x000000020000000000000000 brick 3: trusted.afr.vol1-client-2=0x000010040000000000000000 trusted.afr.vol1-client-3=0x000000000000000000000000 if only brick-2 came up at the time of triggering the self-heal only 'trusted.afr.vol1-client-2' is erased leading to the following xattrs: brick 2: trusted.afr.vol1-client-2=0x000000000000000000000000 trusted.afr.vol1-client-3=0x000000020000000000000000 brick 3: trusted.afr.vol1-client-2=0x000010040000000000000000 trusted.afr.vol1-client-3=0x000000000000000000000000 So the file goes into split-brain.
