I expect a partition sdb1 in sdb disk when i create a directory. How can i do that?
You can expect whatever you want - but YOU must make it happen!
Proxmox has attached a RAW & unformatted disk called
scsi1 in the VM config. Proxmox has allocated that virtual disk on the
Plex storage which appears to be on that
nvme0n1p1 partition. However, the VM itself has actually no idea where this is actually located - all it sees is a RAW & unformatted disk which the VM appears to have named
sdb . (Do not confuse this with
sdb on the host
lsblk output, as this is the hosts' disk layout & that
sdb is probably some usb/card removable storage device). To get your head around this - you could try running
lsblk INSIDE the VM to see how it recognizes its' disks.
You will need to partition & format that
sdb disk
INSIDE the VM. You can search general Linux commands on how to do this.
