Currently I have a superuser post asking if I can install/upgrade existing LUKS/LVM without having to erase and rebuild the partitions. This has provided instructions to mount the HDD, but there are errors. I've reprinted the steps below and indicated the error I'm experiencing. Another post on the same topic offers the same advise, but doesn't seem to have the same problems that I'm having.
My goal is to determine if I can upgrade using the existing LUKS and LVM. However, the problem is the same if I wanted to perform fsck operations on my internal HDD booting from LIVE media CD.
One: Open up the encrypted volume
su -
cryptsetup luksOpen /dev/sda3 cryptLVM
Two: Create all necessary directories:
2.
mkdir /mnt/{home,proc,dev,sys}
Three: Mount LVM:
3.
mount /dev/mapper/cryptVG-root /mnt
mount /dev/mapper/cryptVG-data /mnt/home
Four: Mount all system file systems:
4.
mount -t proc /proc /mnt/proc
mount --bind /sys /mnt/sys
mount --bind /dev /mnt/dev
The trouble occurs between 3-4.
> mount: you must specify the filesystem type
If I specify -t ext4, then I get another error.
> mount: special device /dev/mapper/cryptVG-data does not exist
UPDATE: I also have a post about the LUKS/cryptsetup name value as I try to figure out how these actions cooperate to mount HDD.
