I just noticed something on my homelab server the other day, and while i am sure it is an issue, i don't know how much of an issue it might be.
i have an old lenovo minipci running proxmox ve 8 (pve-manager/8.4.19/a68fb383814bb1e6 (running kernel: 6.8.12-23-pve )to be exact)
it has an old usb external drive doing passthrough to one of the VM's and i noticed something weird the other day.
on the server itself, if i look at block devices (lsblk -f) i get this - sdc being the passthrough device:
but if i log in to the vm itself and look at the device with the same command i get this:
i.e. the device has 2 issues:
im not too concerned about the UUID thing as much as i am concerned about the file system thing. i am currently backing up the drive leaving it in place on the VM as to do my best to keep whatever is on it from getting corrupted in any way, then i plan on reformatting the drive so the file system matches in and out of the virtual environment.
am i right to be concerned here? maybe i dont understand the passthrough process as much as i thought but i am very interested in how this happened in the first place, tho i doubt i will ever figure that out.

sdc└─sdc1 btrfs cb30a...but if i log in to the vm itself and look at the device with the same command i get this:
sdc└─sdc1 ext4 1.0 67ad....i.e. the device has 2 issues:
- why does the bare metal detect the drive as being BTRFS and the vm using it on passthrough detect it as being EXT4?
- why does it have a different UUID?
