[root at 82 /usr/home/denis]#  mount /dev/raid5/data /home/esc/daemon/upload/dl2
mount: /dev/raid5/data: Operation not permitted

[root at 82 /usr/home/denis]# tail -f /var/log/messages

When I try fsck I get:

fsck: Could not determine filesystem type

[root at 82 /usr/home/denis]# fsck_ufs /dev/raid5/data
** /dev/raid5/data
BAD SUPER BLOCK: VALUES IN SUPER BLOCK DISAGREE WITH THOSE IN FIRST ALTERNATE
ioctl (GCINFO): Inappropriate ioctl for device
