Hi! found myself stuck on a weird situation.

After a power failure during night, my nodes got affected. After restarting, a single virtual machine i was testing to learn about High Availability got separated from its disk.

I'm using local storage on every node, so the environment is a 3 nodes setup, everyone with local storage.

After power failure, i found the virtual machine micrated to another node while it's disk remain on the source node:

So i'm lacking the knowledge to move that disk or i'm making so many things wrong. Neither do i'm able to migrate de VM:

One of the HA requirements is shared storage (like Ceph or NFS etc.) (or replication, which requires ZFS) and local-lvm does not provide that: https://pve.proxmox.com/pve-docs/pve-admin-guide.html#_requirements_3
It's clear that replication/HA wont work without shared storage solution/environment.

As the disk is "still there" and also de VM. ¿This is a no-return situation, or may i recover functionality?

Like, may i move VM and pair with storage, may i move storage and reconfigure to VM, may i create a new VM and asign that disk?

I'm interested to recover it as the earliest backup is from august and wopuld like to take a look on the information gathered by the zabbix server had running on that VM, however isn't a critical situation i'm curious on fail recovery procedures...
 
as easy as that...

dissociated disk may be recovered by moving VM (and knowing how to do it).

Dammit, Thanks!
