Hi.
Few minutes ago, being too tired, I unfortunately did a mkfs.ext3 on an
already existing ext3 fs (instead of fsck.ext3).
It unfortunately didn't warn me that there's already an fs on it but
started right away with it's evil work[0] until I ^C-ed it[0] in panic.
I know this list is about devel, but unfortunately I don't know a better
place to ask experts (sorry).
When I scan the fs with testdisk it seems to find some superblocks, having
the old fs label:
superblock 32768, blocksize=4096 [data1]
superblock 98304, blocksize=4096 [data1]
superblock 163840, blocksize=4096 [data1]
superblock 229376, blocksize=4096 [data1]
superblock 294912, blocksize=4096 [data1]
superblock 819200, blocksize=4096 [data1]
superblock 884736, blocksize=4096 [data1]
superblock 1605632, blocksize=4096 [data1]
superblock 2654208, blocksize=4096 [data1]
superblock 4096000, blocksize=4096 [data1]
Could it be that these are still valid ones?
When I try to mount e.g.:
# mount -t ext3 -o sb=$((32768*4)) /dev/sdc1 /mnt/
mount: wrong fs type, bad option, bad superblock on /dev/sdc1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
...it doesn't work however.
Any ideas?
Thanks,
Chris.
btw: Please CC me as I'm off list.
