1) Create a replicate volume.
2) Bring one of the bricks down.
3) create some files:
for i in {1..10}; do dd if=/dev/zero of=$i bs=1M count=10; done
4) execute gluster volume heal info

Created attachment 617990 [details] glustershd log file. Description of problem: ------------------------- In the self-heal daemon log messages we see "inode link failed on the inode (00000000-0000-0000-0000-000000000000)" when self-heal daemon is self-healing Virtual Machines.

Create distribute replicate volume (2 x 2) . 4 servers, one brick on each server. Brick details: brick1:- rhs-client6.lab.eng.blr.redhat.com:/disk1 brick2:- rhs-client7.lab.eng.blr.redhat.com:/disk1 brick3:- rhs-client8.lab.eng.blr.redhat.com:/disk1 brick4:- rhs-client9.lab.eng.blr.redhat.com:/disk1 2. Powered OFF hosts rhs-client7.lab.eng.blr.redhat.com and rhs-client9.lab.eng.blr.redhat.com 3. Created new VM's from RHEVM. 4. Powered ON hosts rhs-client7.lab.eng.blr.redhat.com and rhs-client9.lab.eng.blr.redhat.com 5. self-heal daemon starts self-healing newly created VM's on to bricks "brick2" and "brick4" Actual results: --------------- [2012-09-26 11:52:00.358377] I [client-handshake.c:1614:select_server_supported_programs] 0-replicate-rhevh-client-1: Using Program GlusterFS 3.3.0rhsvirt1, Num (1298437), Version (330) [2012-09-26 11:52:00.358754] I [client-handshake.c:1411:client_setvolume_cbk] 0-replicate-rhevh-client-1: Connected to 10.70.36.31:24012, attached to remote volume '/disk2'.
