* cluster/afr: Don't try to self-heal if there are locks heldVikas Gorur2009-10-301-0/+3
| | | | | | | | | | | If the inodelk_count or entrylk_count is positive on a file/directory, don't try to do self-heal on it. Signed-off-by: Vikas Gorur <vikas@gluster.com> Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 326 ([2.0.8rc9] Spurious self-heal) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=326
* prevent spurious unlocks from afr selfhealAnand Avati2009-10-131-0/+1
| | | | | | | | | | afr selfheal now remembers all the nodes on which locks were successfully held and sends unlocks only to those nodes Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 112 (parallel deletion of files mounted by different clients on the same back-end hangs and/or does not completely delete) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=112

* cluster/afr: dir-write: Fix inode number handling.Vikas Gorur2009-09-281-0/+1
| | | | | | | | | | | | | | | | | | | 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.

* cluster/afr: Return same inode number in stat buf for readv_cbkVikas Gorur2009-07-271-0/+1
| | | | | | | | | | Remember the inode number that had been returned in lookup_cbk and set the stat buf->ino to the same. Signed-off-by: Anand V. Avati <avati@dev.gluster.com> BUG: 166 (libglusterfsclient: Cached stat buf inode is different from ino in inode_t) URL: http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=166

* Return stat info from read-child in all the inode-write opsVikas Gorur2009-07-271-0/+10
| | | | | | | | | | | Also modifies the inode-write ops to wait for the call to read-child to return (whether success or failure) before unwinding. Signed-off-by: Anand V.

* Return inode number always from the first up subvolume in AFR.Vikas Gorur2009-07-091-0/+1
| | | | | | | Also fixes a bug in the "KLUDGE" part. It was setting lookup_buf when it should have been setting local->cont.lookup.buf Signed-off-by: Anand V. Avati <avati@dev.gluster.com>
* Use original pid when calling the FOP in afr transaction.Vikas Gorur2009-04-161-1/+3
| | | | | | | | Save the original pid while locking and restore it after the FOP is done. This ensures posix-locks can release locks (fcntl) properly. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>

* Consider a subvolume dead if an fop fails on itVikas Gorur2009-04-071-0/+2
| | | | | | | | | Transaction fops earlier called afr_transaction_child_died only if an fop failed due to ENOTCONN or EBADFD. Now they consider a child dead regardless of the reason for failure. This handles cases such as ENOSPC. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
