Perhaps I'm just overlooking it but I'm not seeing anything in the messages that appears to be a block number. Maybe 1633350398 but if so it is not a match. Anyway, since you didn't specifically say a new/fixed version of fsck was imminent and that it would likely fix this we began plan B today. We plugged in another drive, placed a GFS2 filesystem on it and am actively copying files off to it now. Fingers crossed that nothing will hit a disk block that causes this again but I could be so lucky probably... Thanks. Unlinked block found at block 37974707 (0x24372b3), left unchanged.
