[ovirt-users] Re: How to keep VM running when a storage domain is offline
You need replicated gluster storage for that. So that one part of the
storage can go down but two others still keep on running. And you need to
set the threshold so that a quorum of 2 is sufficient (if you have replica 3).
If the storage volume is offline. It would be the same as the same thing as
if you pulled the hard drive from a server.
So if ovirt wouldn't pause the virtual server then Linux would complain and
set it to read only.

Hello,
I am trying to understand how I can prevent a VM from being paused when one
of it's disks is unavailable due to a problem with the storage domain.
The scenario:
A VM with 3 disks. OS disk on a highly available domain. And Two large
disks each on separate domains. (so a total of 3 domains).
The two large disks are mirrored using ZFS - but when one of the storage
domains goes down the VM pauses. Is is possible to configure the VM to not
pause when certain storage domains are unavailable? So instead of getting
Paused due to IO error the disk would just be missing until that domain was
brought back online?
Thanks,
-Matthew
