I have a Xpenology DSM 6 running on Proxmox successfully for several months now, and I am testing emergency scenario's such as how to recover the data in case something goes very bad.
The system has 2 X 8TB disks that I have mirrored with mdadm in a plain debian prior to installing Proxmox. I don't have any spare disks that I can "passthrough" to Xpenology.
At this moment I am testing different storage types, and trying to mount them on other linux VM's in case something goes wrong.
What works well is a SATA disk on the local storage with a QCOW2 image, I can mount that on another VM and read the data.
But when using a SATA disk as an image, I can see that there is an LVM created for that storage, but I cannot get to that data unfortunally.
Any idea ?
Charles.
