[Gluster-users] Self heal issues

So the nodes 3 and 6 seem to indicate inode-locks and lookups are of the 
highest latency. This only seems to confirm self-heals are happening.
If you are unable to use the system because of this, you could try 
killing the self-heal daemons on both these nodes (kill `pgrep -f 
glustershd`) to stop heals. You can then do a lookup of the files from 
the mount, which will also trigger heals.
Restart the selfheal daemons  (with `gluster vol start volname force`) 
when you think you can spare the volume for heals again. The sooner the 
better though.
For the brick log errors, we are suspecting it could be something 
related to selinux.

Can you tell what kind of data is there in your volume? - no. of files, 
avg. file size, brick size, network connection speed etc? Perhaps we can 
try to reproduce the issue and identify the bottle neck.

Thanks,
Ravi
