Subject: Cannot map rbd image with striping!
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?
Thanks,
Hadi
