Does the badblocks count or anything ? With me it counted. You have to write the bad block no's to a file and feed that to the=20 reiserfschk. I didn't completed a full badblock check coz I knew the badblocks could=20 only be at the beginning of the lvm 'array', but I excpect it to take as=20 long as a reiserfsck --tree-rebuild. If you don't see anything counting -- start worrying. Good luck to you to. I have still 18 hours to go... I realy hope I can mount the dam thing=20 after that and then I can start looking for the bad disk. And I'm not using any type of raid for that data. kind regardes, Matthias.
