[Gluster-users] Brick Reboot => VMs slowdown, client crashes

[Darrell Budic]

You also need to make sure your volume is setup properly for best performance. Did you apply the gluster virt group to your volumes, or at least features.shard = on on your VM volume?

Also, it was discussed that shutting down the node, does not stop the bricks properly and thus the clients will eait for a timeout before restoring full functionality.  You can stop your glusterd and actually all processes by using a script in /usr/share/gluster/scripts (the path is based on memory and could be wrong).
