Why are you using it?
For LXC it's required, as this maps the rbd image, so it can be mounted by lxc. >> >>> Why are you changing striping parameters? >> We have some write intense tasks to perform and stripping can boost write >> performance.

The first one, had to do with the VM I was testing, once I tried the same setup with a different VM it gave me the second issue. Apparently there is a difference between mon_host address list formatting with comma or space between IPs. ==with KRBD== monhost 192.168.4.50,192.168.4.51,192.168.4.52 ==w/o KRBD== monhost 192.168.4.50 192.168.4.51 192.168.4.52 ==error message== kvm: -drive file=rbd:rbd2/vm-101-disk-1:mon_host=192.168.4.50,192.168.4.51,192.168.4.52:id=admin:auth_supported=cephx:keyring=/etc/pve/priv/ceph/rbd2.keyring,if=none,id=drive-virtio0,cache=writeback,discard=on,format=raw,aio=threads,detect-zeroes=unmap: Block format 'raw' used by device 'drive-virtio0' doesn't support the option '192.168.4.51' Now, is this a ceph issue or proxmox? I will send a new email to follow up on this separately.
