I'm now finding myself a cable to connect these hosts directly.
Next question: can I now depend on my data being the same over both disks? Should I run an online verify? Or is the fact that it caught the problem and stopped enough to ensure integrity?
I would like to run a verify regularly, but I ran into a problem. I added the verify-alg parameter to the net section of my resource, but drbdadm complains when I adjust:
net {
cram-hmac-alg sha1;
shared-secret avnerunvaadsf4n4nn4b4bnb4ai4jfaoi4hf;
after-sb-0pri discard-zero-changes;
after-sb-1pri discard-secondary;
data-integrity-alg md5;
verify-alg md5;
}
root at kvm-host-01:~# drbdadm adjust host1
drbd.d/host1.res:22: Parse error: 'an option keyword' expected,
but got 'verify-alg'

I guess the syntax has changed. How do I enable this in Lucid's DRBD 8.3.7?
root at kvm-host-01:~# cat /proc/drbd
