I had installed DRBD about 3 days before I installed heartbeat. There didn't seem to be any problems until heartbeat was running. But that could just be coincidence. The problem could have been there and just hadn't manifested itself yet probably because I didn't have the backups running right then. The hangs don't occur regularly. Sometimes it will go two, three days without hanging. Other days it might hang twice in the same day. The only common observation is that so far it's always on the primary. Never had the secondary hang. So it's when the array is visible. I'm going to think about my options here. The last time I built a custom kernel it took me forever to debug the thing and get it compiled right. I might just shrink a filesystem/LV/md/partition and put a small LV for the metadata directly on a new partition. All the disk slots are full in the case so this looks like it might be the easiest right now. Gerry
