Will do. With "dump", do you want me to just use "drbdadm dump-md"? Or
really dump the low level data to a file for analysis/comparision?

External. Btw the full "drbd dump" was attached to the original mail,
together with an strace of the drbdsetup call (if that could help). It
doesn't show much except that the ioctl to setup the drbd device fails.
Relevant section of drbd.conf (drbd5 is the only resource right now):
device /dev/drbd5;
disk /dev/vmg/vmA5;
address 192.168.1.205:7795;
meta-disk /dev/vmg/drbdmeta[5];
I will test with internal meta data. Or with an index of [0].
