Well, I did a few more tries and it looks like this: - enter mount command - short blinking on the RAID disks - about 1/2 second later box hangs > > Step one is to figure out if the problem is reiserfs or 3ware.

Ok, I tried this. debugreiserfs runs without any problems. Disks show quite an activity, the whole thing lasts 1-2 minutes. mount afterwards shows the same hang. > Or if this one suceeds, then may be reiserfsck --check /dev/xxxx to get > journal replayed. This is in case access pattern matters. I can try that, too. What do you expect to see? Regards, Stephan
