Hi Cephers, Here is the problem I am facing. I would like to use striping feature with rbd. When I create an image with striping arguments defined, I cannot map it: [cephuser@node01 ~]$ rbd create ceph-client0-rbd0 --image-format 2 --size 10240 --stripe-unit 65536 --stripe-count 4 [cephuser@node01 ~]$ sudo rbd map --image ceph-client0-rbd0 rbd: sysfs write failed rbd: map failed: (22) Invalid argument However, when I create an image without striping arguments, it gets mapped with no problem: [cephuser@node01 ~]$ rbd create ceph-client0-rbd0 --size 10240 [cephuser@node01 ~]$ sudo rbd map --image ceph-client0-rbd0 /dev/rbd0 Any thoughts what could go wrong?
