Hi,
I'm seeking expert help/opinion on my current problem: I cannot access a
LUKS encrypted volume anymore. There are 2 possibilities I currently
think of:
1) different keymap when creating the LUKS volume (unlikely, this system
runs since a long time without changing sth. there), or major brain
damage/confusion when creating the volume.
2) online resizing of LUKS volumes somehow corrupts it.
I have a second volume data1 with same passphrase, therefore I don't
think I've lost it.
To judge if 2) is also unlikely, I need experts with deeper insight into
the LUKS/encryption mechanism.
>From my bash history, the relevant commands were:
867 cryptsetup luksFormat /dev/vg0/data
868 cryptsetup luksOpen /dev/vg0/data data0
869 mke2fs -j -E resize=88888888 -T largefile /dev/mapper/data0
870 tune2fs -c0 -i0 -m2 /dev/mapper/data0
871 tune2fs -c0 -i0 -m2 -L data0 /dev/mapper/data0
872 tune2fs -c0 -i0 -m2 -L data0 -M /data /dev/mapper/data0
1377 lvresize -L +10g /dev/vg0/data
1378 cryptsetup luksResize
1379 man cryptsetup
1380 cryptsetup resize /dev/mapper/data0
1381 ext2online /data
Then I rebooted some time, and now I can't get the volume mounted
anymore ("Command failed: No key available with this passphrase.").
Has someone hints if the online resizing could be the reason for that?
Best regards,
Uwe
