I get the error "unknown filesystem type 'LVM2_member" when trying to mount a LVM-Thin

[Adrian111999]

After typing:
mount /dev/sdb1 /mnt/pve/Storage

I get this error:
mount: /mnt/pve/test: unknown filesystem type 'LVM2_member'.
dmesg(1) may have more information after failed mount system call.

You can't mount an lvm-thin. It is a block storage that PVE normally uses to hold VM disks. What are you trying to do? Perhaps you need to read the manual that is linked at the top of the web GUI, or here:

Looks like it's an LVM PV, not a standalone filesystem. Should show up in ' (pvs; vgs; lvs ) |less '

Check ' df ' and see what's mounted

Few additional commands that may be helpful:
lsblk
blkid
fdisk -l
