<p class=MsoNormal><span lang=EN-US>The volume is used as a shared filesystem
for kvm, but when i was doing some maintenance work on one of the servers, say,
sy-host-2, i stopped glusterd daemon, after the maintenance work done , i
started glusterd daemon, but as soon as the process was up, some of the vm was
hanging, can not ssh to the vm. I was thinking if there was something to do
with glusterd daemon,so i tried to stop the daemon just started, bang~~,
everything was back to normal<o:p></o:p></span></p>
