How can the primary ever be a > server for anything other than itself? /proc/drbd reports "ServerForDLess" if we are connected, we have a disk ourselves, but the we know the peer is diskless. regardless of "primary" or "secondary". so what. maybe we change this, but this is cosmetics only. > I have tried this with the crashing computer running 0.7.14 and kernel > 2.6.15 and again with 0.7.16 and kernel 2.6.16-rc4. > > I have also swapped out the RAID card and moved it to a different PCI > slot.
