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.

Custom striping settings (i.e. non-default stripe_unit and
stripe_count) are not yet supported by the kernel client.
Unrelated, why are you using sysfs directly instead of rbd cli tool?
Thanks,
Ilya
