Hello,
I'm currently migrating one of my systems from linux to fbsd, and i've
chosen the ext2 fs as most compatible one.
Problem is, i cannot mount it.
mount -t ext2fs /dev/ad8p1 /tmp/ext2/1
mount: /dev/ad8p1 : Invalid argument
ext2fs: ad8p1: wrong magic number 0 (expected 0xef53)
It mounts normally under linux, and i've fsck'd it.
Also, under fbsd i cannot even run fsck:
fsck_ext2fs /dev/ad8p1
e2fsck 1.41.9 (22-Aug-2009)
/sbin/e2fsck: Superblock invalid, trying backup blocks...
/sbin/e2fsck: Bad magic number in super-block while trying to open /dev/ad8p1
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
I've found the sb backups with testdisk and tried the e2fsck -b
<superblock_num> -B <block_size> <dev> - doesn't work, returns the
very same message as above.
Any suggestions?
