* cluster/afr: Don't mark the fop as failed if rmdir returns ENOTEMPTY.Vikas Gorur2009-12-031-1/+1
| | | | | | | | | | | Marking the fop as failed in the ENOTEMPTY case led to spurious entry self-heals. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.

* cluster/afr: Do self-heal on unopened fds.Vikas Gorur2009-11-251-0/+17
| | | | | | | | | | | | | | This patch completes the previous patch for self-heal of open fds in replicate. If an fd was never opened on a subvolume, we remember that and do the open after we've done self-heal on that fd. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V.

* cluster/afr: dir-write: Fix inode number handling.Vikas Gorur2009-09-281-24/+40
| | | | | | | | | | | | | | | | | | | create, mkdir, symlink, mknod: Prefer to return itransform'd inode number from the first_up_child. If not, fall back on any other child that returned succcess. link, rename: Return the same inode number that was passed as part of loc_t. Also adds a new member to afr_local_t, local->first_up_child which is initialized at the start of the transaction. This fixes the race where a subvolume might go down during the transaction and thus have the first_up_child change. Signed-off-by: Anand V.
