I installed my proxmox using 2 disk (sda and sdb).. proxmox was installad in sda and sdb was ZFS . Everything went on very well and I created my vms as well.
After sometimes, i wanted to add a new disk, so i removed the sdb disk. but after rebooting, i am having the error PVE GROUPE not FOUND.
The problem is i donot have the sdb disk again ( i formatted it)..
How to solve this issue?
 
can you boot with a live iso and check what is on the /dev/sda disk? (e.g. with lvdisplay/lsblk/etc.)
 
what does pvs, vgs, and lvs say?
 
ok so it seems your data is still there but the volume group was renamed to pve-OLD-4886B504

this only happens normally when you install pve but on an unrelated disk there is an old PVE install

are you sure that you did not reinstall pve once with the disk still in there?

in any case you should be able to put the disk back in the server, boot from a live linux cd and rename the volume group with
Code: 
vgrename <old-name> <new-name>

don't do that on the other pve installation, otherwise you have two 'pve' volume groups simultaneously and stuff will break

No i didn't reinstall it with the disk still there

What i did was:

I had my first proxmox instance with two disk, the second disk was fulled.
so i removed it for remplacement but when i rebooted my proxmox,
i started having the PVE Group not found errors, and the boot drops to initramfs shell.

So i installed a second proxmox instance ( in another disk), and i connected my first instance to it.
When i did PVS, i realized it was renamed to pve-OLD-4886B504 but my data are still there but not accessible.

I will do as you recommended.

Thanks.
