Hi Dieter,
you have a problem with your command.
You set order = 16 so your RBD objects is going to be 65536 bytes
Then you tell RBD that you stripe-unit is going to be 65536 which is the size
of your full object.
Either decrease the size of —stripe-unit to 8192 for example
Or increase order s
Hi Greg,
but our default also has stripe-count = 1 so that no more than 1 stripe-unit is
included in each order x object.
So if you do --order 16—stripe-unit 65536 —stripe-count 1 it then works
I’m not sure if this is what you meant.

If the stripe size and object size are the same it's just chunking --
that's our default. Should work fine.

So, should I open a bug report ?
STRIPINGV2 feature was added in Ceph v0.53, and I'm running v0.61 and using
'--image-format 2' during 'rbd create'

I know, that format2 in rbd.ko is supported with kernel version 3.10 and above.
But, if I want to create an rbd-image
only the Ceph Userland services should be involved, shouldn't it ?

BTW the kernel version on the nodes hosting the OSDs processes is
2.6.32-358.el6.x86_64
but I
Please check the kernel version . Only kernel version 3.10 and above are
supported to create format type 2 images.
