Due to several recent power outages and a failed UPS, an encrypted logical volume is no longer accessible. It has been a while but I'm sure the encryption was done by using Ubuntu's installer, so it should be LUKS?
When I try to mount the LV via mapper (
mount /dev/vg_name/lv_name /mnt/vol), I'm told to specify a file type. It was ext4, but that is not accepted.
If I try
cryptsetup luksOpen /dev/vg_name/lv_name crypt1), I get
Device /dev/vg_name/lv_name is not a valid LUKS device.
I do not know the details of the enycryption so
mount -t ecryptfs presents issues.
How do I detect what exactly is wrong? (and then fix it so I can mount it?)
