Resolving Disappearing Storage Issue After Proxmox Update: Retrieving VM Access

[NonoLeRobot27]

Hello,

I had a Proxmox server running version 5.4 that I recently updated to version 6.4.

Initially, my Proxmox server had several physically attached disks for storage purposes.


However, after the upgrade, the storage spaces disappeared, causing my virtual machines to become inaccessible through the interface.



I am now seeking the method to reattach my storage spaces and regain access to my virtual machines. How can I proceed to restore these connections and access my VMs again?

Thank you,

Arnaud

I assume that you followed the documentation from Proxmox (https://pve.proxmox.com/wiki/Upgrade_from_5.x_to_6.0). Therefore, you can simply recreate your storage from /etc/pve/storage.cfg and have all the necessary data. Ultimately you just have to reinsert them under Datacenter -> Storage.

Otherwise, please post the contents of /etc/pve/storage.cfg in code tags here (not inline!).

Unfortunately, the file must have been reset during the update!

dir: local
        path /var/lib/vz
        content vztmpl,snippets,images,iso,rootdir
        prune-backups keep-all=1

Okay, then I'll translate that loosely by saying that you didn't stick to the rule that you should create backups beforehand

Are you sure your /dev/sda is the boot disk? Because the /dev/sde has a boot and EFI partition.

Why do you have an mdadm on a single disk /dev/sdb?

Is /dev/sdc and /dev/sdd configured in a SW Raid 1? Then I would say that your path could be /dev/md3, which you can then include.

Thank you so much for your help.I'm able to read the data from my two RAID 1 disks on a PC. I'll be able to retrieve all my data without any issue.

I'm going to reinstall Proxmox, directly to version 8!I believe I'll be faster doing this than trying to troubleshoot my current server.

Yes, that's actually the opposite. I made a mistake. ;-)
