Disk Type is unknown (for old rotational hdd)

[guerby]

Hi,

We have one old hdd where the column "Type" in the "Disks" node view shows as "unknown" (instead of "SSD" or "Hard Disk")

Our proxmox version is 7.4 up to date kernel 5.15.108-1-pve on this server.

Here is smartctl of the disk :

Some linux info:

# cat /sys/block/sdb/queue/rotational
1
# lsblk -d -o name,rota|grep sdb
sdb     1

I don't know what PVE uses for finding out the disk type, any idea? (I didn't check the PVE source code)

Thanks!
