Sorry, I didn't really read your message until the end. Apparently, you only have one cephfs, so the other two pools can probably be deleted. Just to get the full picture, can you share these outputs? ceph orch ls mds ceph orch ps --daemon_type mds You could check the pool stats for those two pools with 'ceph osd pool stats', if they don't contain any data you probably won't see any activity. To remove the (correct) service from cephadm you can either remove it with the dashboard in the "Services" tab or with CLI: 'ceph orch rm <MDS_SERVICE>'. Depending on the output I requested this may not be necessary. But if it is, this would remove the daemons and the service definition, then you can go ahead and delete those pools, again either via dashboard or CLI. Zitat von Dmitry Melekhov <dm@belkam.com>:

Hi,
can you check for existing metadata?
ceph osd pool ls detail --format=json-pretty|grep -A 2 application_metadata
Yes, it is here:
ceph osd pool ls detail --format=json-pretty|grep -A 2 application_metadata "application_metadata": { "mgr": {} } -- "application_metadata": { "rbd": {} } -- "application_metadata": { "cephfs": { "data": "cephfs" -- "application_metadata": { "cephfs": { "metadata": "cephfs" -- "application_metadata": {} }, { -- "application_metadata": {} } ]
So, yes, application is not set on 2 pools.
Not sure if it's the same issue as described here: https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/2NL2Q57HTSGD...
There the fix was to set the the application metadata like this:
ceph osd pool application set <your metadata pool name> cephfs metadata <your ceph fs filesystem name>
Yes, I guess it is another way to fix this- set application on pools.
But I don't sure I need to do this, because looks like I don't use these 2 pools.
I think it is better to delete them if I not need them and if it is safe.
Thank you!

Hello!
I'm very new to ceph ,s orry I'm asking extremely basic questions.
I just upgraded 17.2.6 to 17.2.7 and got warning:
2 pool(s) do not have an application enabled
These pools are
5 cephfs.cephfs.meta 6 cephfs.cephfs.data
I don't remember why and how I created them, I just followed some instruction... And don't remember their state before upgrade :-( And I see in dashboard 0 bytes is used in both pools.
But I have two other pools
3 cephfs_data 4 cephfs_metadata
which are in use by cephfs:
ceph fs ls name: cephfs, metadata pool: cephfs_metadata, data pools: [cephfs_data ]
and really have data in them.
Could you tell me, can I just remove these two pools without application, if everything works , i.e. cephfs is mounted and accessible?
