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

Had to break this up into two messages so the dbrd-user list would accept.

Part 2/2:  grp-01-30-01 (Secondary) logs attached.

Forwarding this to drbd-users list on suggestion from Alan Robertson.

I've been running heartbeat on my two nodes for almost two weeks and 
everything is functioning as it is supposed to with the exception that I 
am getting frequent lockups on the primary server.  It doesn't matter 
which server that I make the primary it will eventually be locked up. 
The lockups are very hard.  There is no response of any kind out of the 
locked up machine.  Sometimes the drive light will be on and sometimes 
not.  The lockups are occurring at times of disk access such as during 
backups or right after I ftp a file or tar file over to another machine 
from the drbd array.  There is very little in the logs.  It just shows a 
big gap and then a syslog restart for when I cold booted the server to 
bring it back up.  I'm going to attach dmesg output and 
/var/log/messages output for both servers.  What should I do to track 
down the source of this problem?


Other info:
drbd is running over logical volume which is over a RAID-1 md array on 
each server.

Both servers were rock stable prior to installing HA.
