volume group pve not found

[bthoven]

I've been using proxmox for a few days; shut it down every night.

I shut it down last night and when booting it up this morning, it show the above message. I can still access Proxmox gui, but all VMs and CTs can't startup. I still can see the ISO, CT, disk images volume, etc. in the webui.

I installed proxmox on my 500GB HDD, I did the update by using the Proxmox GUI (PVE--->Updates) before I shut it down.

Linux pve 5.11.22-5-pve #1 SMP PVE 5.11.22-10, Proxmox 7.0-13

Below is my Proxmox boot disk structure (sdb) which is an external HDD connected via usb3. sda is my Windows internal disk.

I notice that the "/dev/mapper/pve-data' is missing.
Need help.
Thank you.

It is working now.
I issued a command line "vgchange -ay" in console, and it now detects such data volume. Rebooting my server later no longer has such problem.

update: it survived only one boot. Next boot, still get the same message and I have to use such command to reclaim pve-data back. Not sure how to permanently fix this.
