hi Ilya, I had used the below command to create the rbd image
rbd -p fool create strpimg --image-format 2 --order 22 --size 2048M --stripe-unit 65536 --stripe-count 3 --image-feature striping --image-shared I am confused when you say why I use sysfs instead of rbd cli tool. Can you please help me? I dont wish to use qemu or virtmanager. I wish to use this as block device on client PC Thanks.
