I used Luks to encrypt my whole hard drive, and created that
sda drive as a physical volume. Under that volume, I create a volume group
vg00 with my 3 logical volumes
Here is my logical volumes, contained in the volume group
vg00 on physical volume
xubuntu@xubuntu:~$ sudo lvdisplay /dev/vg00 --- Logical volume --- LV Path /dev/vg00/lv00_root LV Name lv00_root VG Name vg00 LV UUID 9bzRlY-LWT3-YBV5-yK9U-s3yT-n8MR-B5HjAP LV Write Access read/write LV Creation host, time xubuntu, 2015-08-28 05:11:15 +0000 LV Status available # open 1 LV Size 12.00 GiB Current LE 3072 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:1 --- Logical volume --- LV Path /dev/vg00/lv01_home LV Name lv01_home VG Name vg00 LV UUID B9Ykg2-65Aq-fOS2-1T9I-msfW-OlLf-yMDJT5 LV Write Access read/write LV Creation host, time xubuntu, 2015-08-28 05:11:29 +0000 LV Status available # open 1 LV Size 15.00 GiB Current LE 3840 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:2 --- Logical volume --- LV Path /dev/vg00/lv02_swap LV Name lv02_swap VG Name vg00 LV UUID HHiMFa-D9fi-RH6B-ITN6-olQW-Fx0A-FSSzsY LV Write Access read/write LV Creation host, time xubuntu, 2015-08-28 05:11:41 +0000 LV Status available # open 0 LV Size 2.00 GiB Current LE 512 Segments 1 Allocation inherit Read ahead sectors auto - currently set to 256 Block device 252:3
fstab is as follows(note I already tried putting /dev/sda UUID as an entry, now commented):
# <file system> <mount point> <type> <options> <dump> <pass> #UUID=d6055580-65af-4ef0-aba5-dfcecaa0c82f none luks defaults 0 1 /dev/mapper/vg00-lv00_root / ext4 errors=remount-ro 0 1 # /boot was on /dev/sdb1 during installation UUID=05b8b1aa-4067-4938-ad02-72c3d7fb7331 /boot ext2 defaults $ /dev/mapper/vg00-lv01_home /home ext4 defaults 0 2 /dev/mapper/vg00-lv02_swap none swap sw 0 0
/etc/crypttab is as follows:
roothd UUID=d6055580-65af-4ef0-aba5-dfcecaa0c82f none luks
At the bootloader unlock screen, I would like to input my one existing passphrase for
/dev/sda drive and unlock the volume group
vg00 which contains the all logical volumes.
I did run
update-initramfs -u after any change to the
When I boot, after the grub screen I am dropped to the Ubuntu shell with:
ALERT! /dev/mapper/vg00-lv00_root does not exist .
I have suspicion that it is a problem with grub due to grub.cfg having its linux
initramfs generated image set to the path of
/dev/mapper/vg00-lv00_root. I obviously need to decrypt
/dev/sda parent physical volume before grub could access this.
Any help is appreciated
