Has it worked before or did it just stop working at some point? What's
the exact command that fails (and error message if there is)?
For the "too many PGs per OSD" I suppose I have to add some other
OSDs, right?
Either that or reduce the number of PGs. If you had only a few pools
I'd suggest to leave it to the autoscaler, but not for 13 pools. You
can paste 'ceph osd df' and 'ceph osd pool ls detail' if you need more
input for that.

Hi Eugen,
Sorry, but I had some trouble when I signed up and then I was away
so I missed your reply.
ceph auth export client.migration
[client.migration]
key = redacted
caps mds = "allow rw fsname=repo"
caps mon = "allow r fsname=repo"
caps osd = "allow rw tag cephfs data=repo"
For the "too many PGs per OSD" I suppose I have to add some other
OSDs, right?
Thanks,
Eugenio

Please provide the requested details.

Hello,
I'm writing to troubleshoot an otherwise functional Ceph quincy
cluster that has issues with cephfs.
I cannot mount it with ceph-fuse (it gets stuck), and if I mount it
with NFS I can list the directories but I cannot read or write
anything.
Here's the output of ceph -s
cluster:
