Gluster users - Sep 2013 - Gluster Cluster

Hi all

I have a glusterfs cluster underpinning a KVM virtual server in a two host
setup. Today the cluster just froze and stopped working. I have rebooted
both nodes, brought up the storage again. I can see all the vm files there
but when I try to start the vm the machine just hangs. How can I see if
gluster is trying to synchronise files between the two servers?

thanks
Shaun

Hi Shaun,

What the gluster volume 's topology? What is the current status of the 
volume? Check gluster log files (e.g. 
/var/log/glusterfs/etc-glusterfs-glusterd.vol.log
  .  if it is a replicate or distribute replicate then you should check 
if split-brain happened using below command line.

# gluster v heal
Usage: volume heal <VOLNAME> [{full | info {healed | heal-failed | 
split-brain}}]
