qm create does not create disk

[FrankP]

Hi,

we have a proxmox 5.2.1 cluster with ceph and i would like to create new vm's with the following command:

qm create 8110 -name vm8110 -bootdisk scsi0 -scsi0 NVME:vm-8110-disk-0,size=60G -scsihw virtio-scsi-pci -memory 8192 -ostype l26 -sockets 2 -cores 2 -cpu host -numa 1 -net0 virtio,bridge=<VLAN>

unfortunately this command doesn't seem to create the mentioned disk scsi0:

qm start 8110
iothread is only valid with virtio disk or virtio-scsi-single controller, ignoring
kvm: -drive file=rbd:NVME/vm-8110-disk-0:conf=/etc/pve/ceph.conf:id=admin:keyring=/etc/pve/priv/ceph/NVME.keyring,if=none,id=drive-scsi0,format=raw,cache=none,aio=native,detect-zeroes=on: error reading header from vm-8110-disk-0: No such file or directory

Why is the disk not created and how can i get qm to create the disk when creating the vm ?

Regards
Frank

there is a special syntax for creating disks with the api:

-scsi0 NVME:60

instead of using the full name (vm-x-disk-y)

Hi! so, how is the full command to create VM and disk at same time?

qm create 107 --name preseed --ostype l26 --cdrom Instaladores:iso/preseed-debian10_v2.iso --cores 1 --memory 1024 --net0 virtio,bridge=vmbr0,firewall=1,tag=11 --scsi0 local-lvm:vm-107-disk-0,size=20G

It´s not working

kvm: -drive file=/dev/pve/vm-107-disk-0,if=none,id=drive-scsi0,format=raw,cache=none,aio=native,detect-zeroes=on: Could not open '/dev/pve/vm-107-disk-0': No such file or directory
TASK ERROR: start failed: QEMU exited with code 1

Thanks in advance!!!

Hi,
as @dcsapak said, you have to use the special syntax --scsi0 local-lvm:20 instead of using a full volume ID --scsi0 local-lvm:vm-107-disk-0,size=20G. When you use the full volume ID, the qm create command thinks that you already have a volume. The full command is

qm create 107 --name preseed --ostype l26 --cdrom Instaladores:iso/preseed-debian10_v2.iso --cores 1 --memory 1024 --net0 virtio,bridge=vmbr0,firewall=1,tag=11 --scsi0 local-lvm:20

in your case.

Thanks! @Fabian_E I tried but it seem that my brain was burnt. It works! Sorry!
