/sbin/vgs 100% cpu usage

[Mark W]

Hello,

I'm running Proxmox on an Intel I7, 16GB RAM, 1x 128GB SSD for Proxmox OS and a 2TB Hard drive for the virtual images. The PCT container image resides on the 2TB hard drive and I backed up the container to the same drive.

The backup was successful. But now I'm currently encountering 100% cpu utilisation caused by /usr/sbin/vgs --noheading --nosuffix --units b --unbuffered --nosuffix --options -vg_name,vg_size,vg_free. Everything has slowed down to a crawl including the Proxmox web interface
.
I've tried rebooting and restarting pvestatd but still facing the same issue

How should I fix this issue?

Please post more logs, mainly dmesg. In what process state is vgs?

Sidenote:
Why would you install the OS on the SSD and the main work load on the disk? Does not really makes sense. You could at least setup your SSD as a caching device for LVM or ZFS.

I had to change the global_filter setting in /etc/lvm/lvm.conf on the proxmox nodes:

global_filter = [ "r|/dev/zd.*|", "r|/dev/mapper/pve-.*|", "r|/dev/pvedata/.*|" ]
