I decided to do some experimenting with snapshots and managed to deadlock my system. (Basically, I had a cron job that was trying to snapshot all my filesystems every 5 minutes - with a view to being able to undo any "accidents" I might make). I'd reached about 5 snapshots per filesystem when it hung. I've found a few other anomolies with snapshots, but deadlocks are undesirable :-(. The system was still running normally, but nothing could access the filesystem. Breaking into 'ps' showed that the deadlocked processes were all waiting on "inode". I've got a crash dump but would like some suggestions on where to start looking. The system is -CURRENT from 7th May.
