Hi All,

I've added a LVM group on my PVE, but from the WEB UI I don't see the VM disks inside it, that I can see with fdisk as below.
What's the issue?
Thank you!

Hello
Do you mean you added the VG at Node > Disks > LVM? Did you check the checkbox "Add Storage"?

Can you give me the output of lsblk, lvs, vgs and pvesm status?
 
Hi Philipp,

thanks for answering!

Ok sorry. I still do not entirely understand the problem. Can you please be more specific what exact output (vm, disk) are you expecting in what GUI window?
 
Not sure if this is your problem but on the screenshot you are looking at Container, not VM Disks.
 
Strange. You should be able to see it. Can i have a look at your /etc/pve/storage.cfg?
 
dir: local
path /var/lib/vz
content backup,vztmpl,iso

lvmthin: local-lvm
thinpool data
vgname pve
content rootdir,images

lvm: old
vgname pve-OLD-95683659
content rootdir,images
shared 0

lvm: pve
vgname pve
content images,rootdir
nodes pve
shared 0
 
Hmmm... are you using thin provision? the disks have the attributs Vwi-a-tz-- where the 't' on position 7 stands for "thin"

If you are using thin provision, you have to add it as 'lvmthin' in your storage.conf (same as your local-lvm), not as 'lvm'.
 
Great Philipp,

I see the disks now!
Just another hint: how to have the VMs back?
Just create new VMs and attach the corresponding disk?

Thank you!
 
That highly depends on the configuration of your VMs. At the very least you have to edit the 'boot' option in /etc/pve/qemu-server/<vmid>.conf to add the scsi device to the boot order. If you have a complex RAID configuration it might be more tricky.

EDIT: When you create new VMs with the same id then the old VMs had, you can use qm rescan to auto assign the discs to the (hopefully) correct VMs

Also when your Issue is resolved, please don't forget to mark the thread as resolved so people find it easier in the future.
 
Great gtrovato,

It might be possible though a bit tricky to recover the vm configurations from your original pve. If they where very complex this might be worth it. Otherwise you probably are faster by recreating.

Tell me if you want to attempt a recovery, so I can assist.
