How to mount PVE LVM to salvage data

[Kooch]

Hello, I am stuck with a bit of a situation in that my Proxmox Dev server at home decided to stop booting following what appears to be an extended power outage...I was at work. I have a big UPS, but the Dell T-610 it's running on must have had to shut down somehow. So, the server boots, but it boots into Emergency Mode following a few dependency errors, and failed Start Jobs for both of the disks that I had installation/swap/data and another with vm data on, and nothing I have tried will allow it to boot into any sort of useful state. I have another disk with a fresh install of 5.1-41, and the new proxmox can see that the old disks are there, but I cannot figure out how to mount it...still a bit of a Linux novice here, but it appears that LVMs are a bit of a challenge, and I do need to get the licensed vms off if I cannot repair the original install, which is/was also 5.1-41 following a functioning dist-upgrade a few days earlier. I do expect that there are a few issues with mounting what amounts to another complete installation of Proxmox since all of the partitions have the same names. I have scoured the internet looking for a similar failure, but i've come up empty. The server is a Dell T-610 with the PERC H700 controller, and neither of the disk were part of a raid, they were just stand-alone VD's as this is a Test/Dev server of mine. I am a well seasoned veteran of VMware vSphere & Horizon, but a small company that I help out has been using Proxmox for a few years, and since I've taken over their IT, I have grown to become quite fond of Proxmox and all of it's capabilities...which are Free??? OMG, this is wonderful! But, now I need to learn a lot more about it by trying to fix MY dev server...Help. Thank You.

Hi,

Proxmox and all of it's capabilities...which are Free???

Proxmox VE is aGLPv3, so yes no license charge.
