With that missing it won't start in disconnected mode. It looks like you can't specify the size anymore in 0.7.x, so the solution is to force device names via udev rules and to create a 260M mirrored device to hold external meta-data info (2x128M + extra for linux raid metadata) so that the metadata for each device was available regardless of which disk was missing. DRBD now comes up in disconnected mode and everything is sweet. Have to do some testing to see whether having external metadata on both disks (via the md device) is better served by equal or different group numbers. The man pages would suggest the latter. Admin
