You should probably enable the application "cephfs" on the fs-pools.
it's already activated : pool 1 'cephfs_data' replicated size 3 min_size 2 crush_rule 0 object_hash rjenkins pg_num 256 pgp_num 256 autoscale_mode warn last_change 83 lfor 0/0/81 flags hashpspool stripe_width 0 expected_num_objects 1 application cephfs
In both your cases, the osd caps should read
caps osd = "allow rw tag cephfs data=cephfs_metadata, allow rw pool=cephfs_data"
Currently, I have this and it works: caps: [osd] allow class-read object_prefix rbd_children, allow rw pool=cephfs_data I opened a bug on tracker : https://tracker.ceph.com/issues/43761
This is independent of the replication type of cephfs_data.
Yup, this is what I understood. Yoann

Hi Frank,
for some reason, the command "ceph fs authorize" does not add the required permissions for a FS with data pools any more, older versions did. Now you need to add these caps by hand. It needs to look something like this:
caps osd = "allow rw tag cephfs pool=cephfs_data, allow rw pool=cephfs-data"
an easy way is:
- ceph auth export - add the caps with an editor - ceph auth import
I consider this a bug and thought it was fixed in newer versions already.
Sorry, I had a typo. If you have separate meta- and data pools, the data pool is not added properly. The caps should look like:
caps osd = "allow rw tag cephfs pool=cephfs-meta-pool, allow rw pool=cephfs-data-pool"
If you don't have a separate data pool, it should work out of the box.
Thanks, for the feed back, I also got that information from dirtwash on the IRC channel that fix my issue. And yes for me it's also an issue.
But I have another cluster also on ubuntu 18.04 (4.15.0-74-generic) and Nautilus 14.2.6 installed one week before and it works. I did the same command on both and I don't have the same behaviour.
there are few diff between the 2 clusters, not the same hw config (No SSD on the dslab2020 cluster) and cephfs_data on an 8+3 EC pool on Artemis (see the end of artemis.txt). in attachement, I put the result of the commands I did on both cluster without the same behaviors at the end.
Best,
Yoann

Hello,
On a fresh install (Nautilus 14.2.6) deploy with ceph-ansible playbook stable-4.0, I have an issue with cephfs. I can create a folder, I can create empty files, but cannot write data on like I'm not allowed to write to the cephfs_data pool.

I don't where to look to get more information about that issue. Anyone can help me? Thanks
