Urgh!<br>
IIUC you're begging for split-brain ...<br>
I think you should leave quorum-count=2 for safe writes. If a node is<br>
down, obviously the volume becomes readonly. But if you planned the<br>
downtime you can reduce quorum-count just before shutting it down.<br>
You'll have to bring it back to 2 before re-enabling the downed server,<br>
then wait for heal to complete before being able to down the second server.<br>

Isn't it preferrable to use the 'hostlist' syntax?<br>
gluster01,gluster02:VMS /vms glusterfs defaults,_netdev 0 0<br>
A / at the beginning is optional, but can be useful if you're trying to<br>
use the diamond freespace collector (w/o the initial slash, it ignores<br>
glusterfs mountpoints).<br>
