Check HardWare Config of VM in Proxmox GUI
Navigator to the specific VM to which a disk is to be added.
In the Hardware there should be:
- A SCSI Controller.
- A Hard Disk (scsi0).
NOTE: This shows that there is a single Hard Disk scsi0.
- But the SCSI Contoller can also support additional Hard Disks named:
- scsi1
- scsi2
- …and so on…
Check also the Config File of the VM
cat /etc/pve/nodes/pve/qemu-server/122.conf
returns:
balloon: 8192 boot: order=scsi0;ide2;net0 cores: 4 cpu: host efidisk0: VM1:vm-122-disk-1,efitype=4m,pre-enrolled-keys=1,size=4M ide2: none,media=cdrom machine: q35 memory: 16384 name: TrueNASScale net0: virtio=46:23:DF:15:1D:F6,bridge=vmbr1,firewall=1 numa: 0 ostype: l26 scsi0: VM1:vm-122-disk-0,size=32G scsihw: virtio-scsi-pci smbios1: uuid=b1bc7679-4024-4814-ac1f-05d4d13c94a2 sockets: 1 vmgenid: 976e446a-7469-4f60-ae71-e95101357f14
Add a Disk to the VM
qm set 122 -scsi1 /dev/disk/by-id/ata-ST16000NM001G-2KK103_ZL2JTP65
returns:
update VM 122: -scsi1 /dev/disk/by-id/ata-ST16000NM001G-2KK103_ZL2JTP65
IMPORTANT: Disks need to be identified by their ID and not by their /dev/sdc names.
- The reason for this, is that after every boot the /dev/sdc names may be switched around.
Recheck the Config File of the VM
cat /etc/pve/nodes/pve/qemu-server/122.conf
returns:
balloon: 8192 boot: order=scsi0;ide2;net0 cores: 4 cpu: host efidisk0: VM1:vm-122-disk-1,efitype=4m,pre-enrolled-keys=1,size=4M ide2: none,media=cdrom machine: q35 memory: 16384 name: TrueNASScale net0: virtio=46:23:DF:15:1D:F6,bridge=vmbr1,firewall=1 numa: 0 ostype: l26 scsi0: VM1:vm-122-disk-0,size=32G scsi1: /dev/disk/by-id/ata-ST16000NM001G-2KK103_ZL2JTP65,size=14902G scsihw: virtio-scsi-pci smbios1: uuid=b1bc7679-4024-4814-ac1f-05d4d13c94a2 sockets: 1 vmgenid: 976e446a-7469-4f60-ae71-e95101357f14
NOTE: The scsi1 is showing.
- The GUI should also show this additional drive.
Add Additional Disks as Required
qm set 122 -scsi2 /dev/disk/by-id/ata-ST16000NM001G-2KK103_ZL2JS9LB update VM 122: -scsi2 /dev/disk/by-id/ata-ST16000NM001G-2KK103_ZL2JS9LB
qm set 122 -scsi3 /dev/disk/by-id/ata-ST16000NM001G-2KK103_WL2091XL update VM 122: -scsi3 /dev/disk/by-id/ata-ST16000NM001G-2KK103_WL2091XL
IMPORTANT: For every additional disk, remember to use a different SCSI identifier:
- -scsi2
- -scsi3
