* cluster/afr: Prevent spurious entry self-heal.Vikas Gorur2009-10-231-2/+13
| | | | | | | | | | | | | | If the initial lookup shows that 'pending' is positive, then self-heal will hold a lock and do a lookup again. This lookup might show that 'pending' is zero everywhere. However, entry self-heal used to consider this as a case of 'no sources' and try to merge the directories. This patch checks for that case and does not do the merge. Signed-off-by: Anand V.

| | | | | | | | | | 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
* replicate: fix missing frame in entry-self-healAnand Avati2009-10-121-0/+7
| | | | | | | | | | | when files on all backend nodes are missing, the logic in afr_sh_entry_erase_pending is broken and results in missing lookup frame. this causes processes to enter into uninterruptible sleep state.

* Compulsorily do self heal if file sizes differ.Vikas Gorur2009-04-091-2/+2
| | | | | | | | | If file sizes differ, then compulsorily do self-heal. If no 'wise' sources are found, then pick a 'fool' with the biggest file size. If even 'fools' aren't found, pick the 'innocent' source with the biggest file size. Signed-off-by: Anand V. Avati <avati@amp.gluster.com>
