Re: rbd ls operation not permitted

Thanks, changing rxw to rwx solved the problem. But again, it is strange. I am issuing the rbd command against the ssdvolumes pool and not ssdvolumes-13. And why does "allow *" on the mon solves the problem. I am a bit lost :-)

--
This does work
--
caps: [mon] allow *
caps: [osd] allow *
$ rbd ls -p ssdvolumes --id openstack
volume-e61ec087-e654-471b-975f-f72b753a3bb0
$


--
This does NOT work
--
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx pool=ssdvolumes, allow rxw pool=ssdvolumes-13, allow rwx pool=sasvolumes-13, allow rwx pool=sasvolumes, allow rwx pool=vms, allow rwx pool=images
$ rbd ls -p ssdvolumes --id openstack
rbd: list: (1) Operation not permitted
$

caps: [mon] allow r

Strange thing is, with an older rbd (like we use in Openstack Ocata) we don't see this behavior.

By chance, is your issue really that your OpenStack 13 cluster cannot
access the pool named "ssdvolumes-13"? I ask because you have a typo
on your "rwx" cap (you have "rxw" instead).


On the problematic Openstack cluster:
$ ceph auth get client.openstack --id openstack | grep caps
Error EACCES: access denied
$


When I change "caps: [mon] allow r" to "caps: [mon] allow *" the problem
disappears.
