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 lv00_root, lv01_home, and lv02_swapHere is my logical volumes, contained in the volume group vg00 on physical volume /dev/sdaxubuntu@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           252:3My 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 installationUUID=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       0My /etc/crypttab is as follows:roothd UUID=d6055580-65af-4ef0-aba5-dfcecaa0c82f none luksAt 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 fstab or crypttabWhen 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. FYI I roughly followed this and this tutorialAny help is appreciated
