LVM Caused Data Loss

[Albats]

Hello,

We had just installed Proxmox onto a server and were about to restore from backup. To do this we needed to connect to the NAS' ISCSI LUN. We added the LUN the Storage and then mapped an LVM to mount it. However, this seemed to have erased the entire partition of the LUN and our backup volume is now lost.

Is it a case of hitting the data recovery software, or did the LVM creation not actually erase anything and something else is going on here?

Its not completely clear what you did, but it does appear that you made a mistake in presenting a LUN with existing data to the OS. Without having a good before and after understanding (backed by actual command output) its impossible to say whether your data is erased, recoverable, or intact.
It is, however, pretty certain that what you are dealing with is "Linux system administration", not "Proxmox VE installation and configuration".
