Not something like "can't read superblock" or "is not a valid block device" or similar errors which would indicate an error with the md array. So, maybe mount is right and /mnt/gentoo/raid/ IS actually wrong...? Furthermore, you're not realizing that reiserfs will try to replay its transactions when you attempt a mount, even if mounting RO afaik. So maybe more prudent would be a reiserfsck --check... Maarten
