Greeting to all Proxmox´s community.
I have a tricky problem here with one of our proxmox servers. We had installed in this server the version 3.1, but it seems that for a problem with the disc, the Operating system failed and we had to reinstalled the server, now with the version 5.1.
The problem is that now, pve-data doesn´t show its content. We tried to add the LVM volumen using the Proxmox GUI on the website, but it doesn´t show anything inside, but when we select the volumen, it shows that there is used space: almost 87% actually.
So, we believe that the data is present there.
This is the outputs of pvscan, pvdisplay, lvdisplay, vgdisplay and lvscan:
1. pvscan
2. pvdisplay
3. lvdisplay
4. vgdisplay
5. lvscan
We tried to see what´s happen inside /dev/mapper too with this:
Any suggestion or recommendation is more than welcome. Thanks
