[PVE-User] Ceph RBD image striping

[Alwin Antreich]

Hi all,

how can I create an image with the ceph striping feature and add the disk to a VM?

Thanks in advance.


I can add an image via the rbd cli, but fail to activate it through proxmox (timeout). I manually added the disk file to
the VM  config under /etc/pve/qemu-server/. In proxmox the storage is added w/o KRBD.

rbd -p rbd2 --image-features 3 --stripe-count 8 --stripe-unit 524288 --size 4194304 --image-format 2 create vm-208014-disk-2
