[Gluster-users] Questions related to heal-failed

[shwetha]

1) Usage of gluster volume heal command :

To see list of files that requires self-heal : "gluster volume heal 
<volume_name> info"

To see files that were self-healed : "gluster volume  heal <volume_name> 
info healed"

To see files which were failed to self-heal : "gluster volume heal 
<volume_name> info heal-failed"

To see if files are in split-brain state : "gluster volume  heal 
<volume_name> info split-brain"

2 and 3) Even after executing "gluster volume heal <volume_name>" or 
"gluster volume heal <volume_name> full" which will trigger self-heal , 
you will be seeing stale entries when you execute "gluster volume  heal 
<volume_name> info heal-failed" from the previous execution .If you want 
to overcome this

a) restart glusterd on all storage nodes : "service glusterd restart"

b) Trigger self-heal : "gluster volume heal <volume_name>" or "gluster 
volume heal <volume_name> full"

c) Execute : "gluster volume heal <volume_name> info heal-failed"  to 
check if self-heal has been failed on certain files.

4) Under "/var/log/glusterfs" check glustershd.log file for any 
self-heal related logs.
