[ovirt-users] Missing dom_md/ids file

[Cameron Christensen]

I cannot put the gluster domain into maintenance. I'm believe this is
because the data center has a status of Non responsive (because a host
cannot connect to storage or start SPM). The only option available on
the gluster storage is activate. I have put all the hosts into
maintenance. Is this enough to continue with the initialize lockspace
step?
