Hi,
I do have a super simple setup on fairly old consumer hardware with Proxmox 7 system installed on a 250GB ssd disk (the root partition)
All VM disks are stored in another ssd disk (storage mode directory) , backups are stored on a third disk (storage mode directory)
Both external disks are just mounted via fstab into their dirs. I decided for this setup as my understanding of lvm is very limited.
Now I plan to swap my GPU (different vendor) and upgrade to Proxmox 8.
I didn't do too many customizations on the host (actually a few PCIe passthrough's and a few additional system daemons)
Before I do these upgrades, i wanted to make sure, I can recover more or less easily if i mess it up.
So the idea is to copy the root 250 GB root disk and all its partitions using gparted live cd to an external disk.
In the case my upgrade fails i could always copy back from the external storage to the root disk and just need to fix the bootloader.
While this works well for the first two partitions, the third partition containing the lvm can't be copied to the external disk.
I would need to click on "deactivate" in gparted the partition so i can copy this partition to the external disk.
My question is: Can I safely do that or would i mess up with the lvm in that case?
I know this is more a general question/maybe even gparted related question, not proxmox specific, but maybe someone can share some light.
Alternatively, what would be the proper way of creating a backup of the host system to an external drive?
The backup doesn't need to be flexible, just be able to restore as it is today, if i mess it up.
I don't really care about the VMs as they are anyway separate from that 250GB "root host" disk.
Thanks!
