Hello, after adding a new virtual disc (rados block device) online via
echo "drive_add 0 if=none,file=rbd:it/testsmbverwit:id=kvm,format=raw,id=virtio2" | socat - UNIX-CONNECT:/tmp/alv33.monitor echo "device_add virtio-blk-pci,drive=virtio2" | socat - UNIX-CONNECT:/tmp/alv33.monitor I get the info via 'info block' that the cache mode of the new disk is writeback virtio2: rbd:it/testsmbverwit:id=kvm (raw) Cache mode: writeback Is it possible to change the cache mode to writethrough online?
