Hi Atin,

Earlier i was adding the brick and create the volume through ovirt itself....this time i did it through commandline...i added all 15 bricks 5*3 through command line....

It seems before optimize for virt storage it all ok...but after that one quorum start and it failed the whole...

"Optimize for Virt" action in oVirt sets the following volume options.

group = > virt
storage.owner-uid => 36
storage.owner-gid => 36
server.allow-insecure => on
network.ping-timeout => 10

Regards,
Ramesh

In one of your earlier email you mentioned that after adding a brick
volume status stopped working. Can you point me to the glusterd log for
that transaction?
