All my vms are gone

[Yakov]

I accidentally forcefully shut-down my server and the proxmox ui stopped showing up. I followed some guides on the forum and that made it worse. The database file is gone. I'm just trying to backup the disks.

I can access /dev/pve when dualbooting on Ubuntu, When I boot into proxmox, there are no vms showing up anymore.

(although it looks like the disks are still intact when on Ubuntu running fdisk -l or lsblk -f)

Please help!

If you need to see anything, let me know

is the pve-cluster service running ?

it should mount /etc/pve , where the vm config are located.

(the true database is /var/lib/pve-cluster/config.db , the the pve-cluster service expose the content in /etc/pve)

It is running, I found a forum post and it told me to delete that DB file.

Well, if you deleted the backing database where most of PVE's configuration files, including VM/CT ones are saved it would explain that those VMs are gone.. That .db file should never be deleted without clarifying with a PVE expert that it actually is required, and even then one does not just delete it, but creates a backup and renames it to another filename, like <old>.bak.

If you have no backups you need to re-create the configuration files, good thing is that you did not remove the disks so can all still be recovered.

Check the list of volumes with pvesm list STORAGE --content images for VMs and pvesm list STORAGE --content rootdir for container.
Create new VMs ideally with the same VMID as then you could re-attach the disks by running qm rescan --dryrun
(note, I added dryrun explicitly to make it safer. Drop that parameter to actually do the actions).

I am currently trying to help @Yakov but.

pvesm list tom-nasi --content images

didn't work. Here are some screenshots.

I think you need to re-add a lvm storage "tom-nasi" in /etc/pve/storage.cfg. (as it's gone too with the removal of /var/lib/pve-cluster/config.db)

That file doesn't exist for some reason. (I have no idea what the file structure looks like)

Hi,
try to re-create the file /etc/pve/storage.cfg with the following contents (default for an LVM-based installation):

dir: local
        path /var/lib/vz
        content vztmpl,iso,backup

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

If you had any more storages configured, just add them via UI or pvesm afterwards.

Alright the images are all showing now. Thanks.
