Ubuntu looks for a removed volume group during boot
It turns out that the traces of LVM were stored in initramfs
. I found the question Can't find LVM root dropped back to initramfs and ran the mentioned command:
sudo update-initramfs -u -k all
Since that, the messages regarding LVM have no more been appearing during boot.

I cloned my Ubuntu Server to a virtual machine on my laptop to do some tests. I adapted
/etc/fstab
and network configuration but I am unable to get rid of LVM. While the original server uses LVM, the clone has a single partition setup:$ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 64G 0 disk └─sda1 8:1 0 64G 0 part / sr0 11:0 1 1024M 0 rom
However, this is still showing during boot:
Volume group "vp11-testsrv-ubuntu-vg" not found Cannot process volume group vp11-testsrv-ubuntu-vg
(I am sorry to post a screenshot of text. Is there any file where I can find these boot messages? I cannot find them in
/var/log
and the output ofdmesg
.)It’s probably just a warning and the boot continues successfully but I want to get rid of the LVM traces. How can I achieve this?
The commands
pvs
,vgs
,lvs
showed nothing and I even ransudo apt remove lvm2
without problems but the boot messages are still there. I also removedlvm
fromGRUB_PRELOAD_MODULES
in/etc/default/grub
and ransudo update-grub
. I have only found traces of the server’s LVM in/var/log
(old records from the original server) and thearchive
andbackup
subfolders of/etc/lvm
.This is my
/etc/fstab
. The commented items are related to the original server.# <file system> <mount point> <type> <options> <dump> <pass> UUID=cbd35c50-81be-4e7f-a412-d1f4bed90c00 / ext3 errors=remount-ro 0 1 # /boot was on /dev/sda1 during installation #UUID=fb5493ef-7c3b-4009-9765-47969fb83b68 /boot ext3 defaults 0 2 #/dev/mapper/vp11--testsrv--ubuntu--vg-swap_1 none swap sw 0 0 #/dev/mapper/vp11--testsrv--ubuntu--vg-vboxes /home/virtbox/VirtualBox\040VMs ext3 defaults 0 2
