Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

I saw someone else post something similar to this a few weeks ago, but 
didn't see any response to it.  I've just set up DRBD 0.7.23 with 
Heartbeat2 on two future database server.  However, DRBD seems to have 
corrupted my multi-disk RAID1.  I booted a Knoppix CD on the affected 
machines, removed the DRBD rc.d scripts, and rebooted and things were 
fine.  To verify, I ran update-rc.d to recreate the symbolic links, and 
rebooted again to find that it again would not boot.  Moreover, even 
removing the rc.d links did not help - the array is, I fear, irreparably 

Is there any acknowledgement of this bug, or are there any suggestions 
as to how one might go about fixing it?  I can't even boot into the 
machine to run mdadm and repair the array, though maybe I can do that 
from the Knoppix CD...

In any case, I just wanted to make people aware, and hopefully get a 
little feedback.  Thanks.
