Comment 4 for bug 1858839

Knobby apparently can't comment on this bug, but wanted me to pass along that RWX Block mode is not supported unless you have Ceph version >= Mimic (v13). You can see that in the support matrix I linked above.

Of course, the support matrix also says Mimic is required for RWO File mode PVs but those seem to work on v12 anyway. Maybe there's some way to get RWX Block mode to work on v12, too, but I'm not very optimistic.
