after the reboot I was able to open the encrypted file system but wasn't able to mount the lvm because /dev/lvm/volume didn't exist but lvscan did show the volume group and the volume.
So my question is which comes first the encryption of the lvm ?
should I setup a lvm then encrypt that or setup a encrypted volume then the lvm?
I am running Centos 5.5
You should be able to mount it by using /dev/mapper/luksname
e.g. I named my luks encrypted LV lukslv
(I know, I know, such boundless creativity should be channelled towards writing books or something).
I can mount it, to a directory called /lukstest, by typing
mount /dev/mapper/lukslv /lukstest
In /etc/crypttab, you need the following, in my case:
lukslv /dev/vol1/lv4 none
where /dev/vol1/lv4 is the original LV
If you have forgotten the name, you can get the name by using blkid
. Somewhat confusingly, you want to use the entry whose type is NOT crypto_LUKS
/dev/mapper/vol1-lv4: UUID="0714a501-ba01-4eb1-be77-690427c8eef8" TYPE="crypto_LUKS"
/dev/mapper/lukslv: UUID="b135d367-ece1-489c-b34f-a0bd6d874199" TYPE="ext4"
Hope this helps.
