    Hello, I am running into issues with corrupted data in VM. I am quite new to Proxmox and do not know how to search to find the reason for as I did a couple of changes in my system.

    [SOLVED] Corrupt GPT after Restore on PVE 7.0 from Backup on PVE 6.4 | QEMU VM, LVM-Thin Storage, OVMF

    Hello everyone I tested whether I could migrate VMs from PVE 6.4-13 to PVE 7.0-11, using backup and restore, which unfortunately fails. Both PVEs share an equal setup except for their Proxmox version, have an LVM thin pooled storage, were installed from Debian (Buster, Bullseye, respectively)...

    2 Different PVE Versions; 2 Different File Systems on 2 Different Drives, But Same PVE Failures

    4 months ago I installed PVE v4.4 on an eXT4 filesystem SSD. I put about 10 different containers on it and was the only user. I didn't use ceph or HA, and I had no other clusters--it was just one node with about 10 different LXCs. All containers were under 50% usage in their allotted storage...
