There are two bugs that may cause the tag to be missing from the pools, you
can somehow manually add these tags with "ceph osd pool application ..."; I
think I posted these commands some time ago on tracker.ceph.com

I did some brute-force experiments and found the
following setting works
for me:
caps osd = "allow rw pool=cephfs_data"
I am not sure why ceph fs authorize command set in that way and for what
purpose...
Cheers

Hi guys,
I have a Ceph Cluster up and running and cephfs created (all done by
ceph-ansible).
I following the guide to mount the volume on CentOS7 via FUSE.
When I mount the volume as the default admin (client.admin), everything
works fine just like normal file system.
Then I created a new client just for FUSE mount purpose, follow this
guide: https://docs.ceph.com/docs/master/cephfs/mount-prerequisites/
The ceph fs authorize command created a new client with the following
caps:
[client.wp_test]
key = AQDAEc9ebLXjGhAAxEGqTuTvCOoN30g4UzF5jw==
caps mds = "allow rw"
caps mon = "allow r"
caps osd = "allow rw tag cephfs data=cephfs"
It can mount the volume, and I can touch a file. But when I tried write
data, such as editing a new text or cat a file, I got some read-only
error
or
[root@mon-6-26 ceph_root]# cat test.txt
cat: test.txt: Operation not permitted
if I modified the OSD cap to "allow *", the it allows write again.
Can anyone suggest what have been done incorrectly?
We are using
14.2.9 (581f22da52345dba46ee232b73b990f06029a2a0)
nautilus (stable)
Cheers,
Derrick
