Dear folks,
I made 18 ext2 cdroms in October 1998 using an old (new at the time) Red
Hat system. Now I can't mount them. e2fsck shows no problems. I also
can dd them to a file, then mount the file. But I want to be able to
simply access them directly. Current system: RH 7.1 with all updates.
Sorry, I can't remember the exact command I used to create the images.
I also want to better understand the output of dumpe2fs, and how to
relate this to mount.
I will be very grateful for any help that increases my understanding of
what is going on.
$ sudo mount -t ext2 /dev/scd0 /cdrom -o ro
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems
Other symptoms:
$ sudo fdisk -l /dev/scd0
Note: sector size is 2048 (not 512)
Disk /dev/scd0: 0 heads, 0 sectors, 0 cylinders
Units = cylinders of 1 * 2048 bytes
Disk /dev/scd0 doesn't contain a valid partition table
$ e2fsck -v -n /dev/scd0 2>&1 | tee e2fsck-v-n-dev-scd0
e2fsck 1.19, 13-Jul-2000 for EXT2 FS 0.5b, 95/08/09
/dev/scd0 has gone too long without being checked, check forced.
