Where does the system show the error (log, on the console)?
Maybe a disk changed, and the change wasn't propagated into all necessary places (e.g. /etc/fstab, /boot/grub/grub.cfg)
If you can get to a console/ssh session on the server you could try:
* grep -ri '3xgMv0-WorN-cif6-vbGC-69ZD-Zujw-PG7jcw' /etc /boot (needs to be run as root user)

i execute command and show this:

/etc/lvm/backup/vg_server: id = "3xgMv0-WorN-cif6-vbGC-69ZD-Zujw-PG7jcw"
/etc/lvm/archive/vg_server_00001-1296367895.vg: id = "3xgMv0-WorN-cif6-vbGC-69ZD-Zujw-PG7jcw"

Where do you get the error-message and when (during boot, in a logfile after the system has booted up (which logfile) )?

what's the output of : lsblk -f ?

Do you experience any problems, apart from the message? (services not starting, VMs/containers not running)?

The message is displayed only if I run console commands or commands on LVM

what's the output of : lsblk -f ?

the output of lsblk -f does not highlight UUID and not error

No problem everything works perfectly

I would just like to remove this orphaned element...

 

[Stoiko Ivanov]

depending on what kind of object this was (PV or LV), it probably got removed without lvm noticing it.
you can see what kind of object it was by reading the file /etc/lvm/backup/vg_server.

Did something change recently with the setup?

Do not change anything, unless you feel confident, and unless you have a backup!

pvscan, vgscan, lvscan could provide you with further information.

OK, thank you for everything!

Hi Stoiko, I have a similar problem:

I have a single server with 2 HD mounted as a directory (for several files only) in raid, one HD for the installation of proxmox and another HD for the virtual machines. The HD of the virtual machines stopped working and I removed it, after that I do not know how to remove this HD from my VG. Also I can no longer see the two mounted HDDs as directory, they simply do not appear anymore in lsblk, blkid, fdisk -l
Please how can i solve it? I do not need virtual machine disks.

Please open a new thread instead of reviving a 7 months old one!
(Also it seems that your problem is a different one - your output suggest that you had 2 disks in one VG, and one disk is gone - thus the VG is not really accessible anymore)
