I used a cryptoloop device with an reiserfs and made a copy/backup of
the file containing the data.
I'm not completely sure, but I think it was mounted, when I copied it.
Maybe this was a mistake.
Now I need the data from the backup and I can't mount the reiserfs using
the cryptoloop device.
dmesg tells me the following:
ReiserFS: loop0: found reiserfs format "3.6" with standard journal
ReiserFS: loop0: using ordered data mode
reiserfs: using flush barriers
ReiserFS: loop0: journal params: device loop0, size 8192, journal first
block 18, max trans len 1024, max batch 900, max commit age 30, max
trans age 30
ReiserFS: loop0: checking transaction log (loop0)
ReiserFS: warning: is_tree_node: node level 123 does not match to the
expected one 3
ReiserFS: loop0: warning: vs-5150: search_by_key: invalid format found
in block 2195471. Fsck?
ReiserFS: loop0: warning: vs-13070: reiserfs_read_locked_inode: i/o
failure occurred trying to find stat data of [1 2 0x0 SD]
ReiserFS: loop0: Using r5 hash to sort names
ReiserFS: loop0: warning: xattrs/ACLs enabled and couldn't find/create
.reiserfs_priv. Failing mount.
An appropriate fstab entry, so a user is allowed to mount the device
looks like this:
/home/userX/data /home/userX/crypto reiserfs
user,noauto,loop=/dev/loop0,encryption=twofish256,phash=sha512,itercountk=100
0 0
I have done a reiserfsck --check, which told me I should run reiserfsck
--rebuild-sb and then a reiserfsck --rebuild-tree. The last one
obviously failed and just told me that there is no reiserfs meta data.
Is there any hope to recover the data or is the filesystem already
completely corrupted?
I want to know, if it is worth a try, otherwise I won't spend time and
money on it.
