[DRBD-user] PingAck did not arrive in time.

Yes, we've tested this approach as well. LVM can join DRBD devices into a single volume. But this way it may be more complicated to bypass drbd in case of any problems with it. A few weeks ago we've grown our volume above the allowed limit and DRBD stopped to work. We were not able to shrink it back because DRBD error appeared in a month time after reboot and we've already started to populate the extended space. With RAID0->LVM->DRBD->XFS we simply changed a mount point from DRBD to LVM volume with minimum impact to operation time. In case of RAID0 -> DRBD -> LVM -> XFS I guess it would be required to recover LVM volume changing DRBD to the physical disks in meta data.

Is it possible to use Linux MD on top of DRBD devices? ie, use /dev/drbd[0-3] to create a RAID0 array?
Or I guess using them as PV's and then creating a single LV across all of them?
