I have several external backup disks encrypted before Luks appeared. After
update from 12.1 to 12.3, losetup is gone and I haven't been able to
mount the encrypted disks.
linux-p22i /root# uname -r
linux-p22i /root# lsmod | grep crypt
cryptoloop 12715 0
loop 27944 1 cryptoloop
dm_crypt 22845 2
dm_mod 92315 4 dm_crypt
linux-p22i /root# lsblk -f -l /dev/sdi1
NAME FSTYPE LABEL UUID MOUNTPOINT
***/dev/sdi1 was previously under 12.1 mounted using losetup***
***Because the partition isn't a Luks partition, I can't***
linux-p22i /root# cryptsetup luksOpen /dev/sdi1 back5
Device /dev/sdi1 is not a valid LUKS device.
So I try a 'legacy' approach per the cryptosetup wiki:
linux-p22i /root# cryptsetup create back5 /dev/sdi1
(which I did; just got newline)
linux-p22i /root# cryptsetup status back5
/dev/mapper/back5 is active.
keysize: 256 bits
offset: 0 sectors
size: 976768002 sectors
***which seems correct to me***
linux-p22i /root# l /dev/mapper/
Now. How do I or what do I mount? I can't use /dev/mapper directly.
I have no success trying to mkfs /dev/back5.
This must be a common problem but I don't find
it addressed in the opensuse forums.
