There used to be / is a bug in ceph fs commands when using data pools. If you enable the application cephfs on a pool explicitly before running cephfs add datapool, the fs-tag is not applied. Maybe its that? There is an older thread on the topic in the users-list and also a fix/workaround.

But my node is also its own client, so there's that. And it was installed with 15.2.4, no upgrade. > For the 2nd, mds works, files can be created or removed, but client > read/write (native client, kernel version 5.7.4) fails with I/O > error, so osd part does not seem to be working properly. You mean it works if you mount it from a different host (within the cluster maybe) with the new client's key but it doesn't work with the designated clients? I'm not sure about the OSD part since the other syntax seems to work, you say. Can you share more details about the error? The mount on the clients works but they can't read/write?
