Are you actually doing that? I once tried mdadm with remote drives, to see if it was a viable alternative to drbd. It fell over at the slightly transient network outage. Unless your network is invincible, I'm not sure this is a case worth thinking about. > if the VM is paused briefly, that would prevent the VM from writing to > the raid array while it was being snapshotted. Simply pausing the VM might not quiesce it -- it'd depend on whether a pause also implies a flush to disk. For example, lxc freeze basically just sends a SIGSTOP to all procs in the group. _______________________________________________ luv-main mailing list [email protected] http://lists.luv.asn.au/listinfo/luv-main
