Yeah, it already exists.


ceph auth  get-or-create mds.mynode mon 'profile mds' mgr 'profile mds'
mds 'allow *' osd 'allow *'

error:
Error EINVAL: key for mds.mynode exists but cap mds does not match

I think the 'get-or-create' won't allow you to change the existing user's caps.

Please see https://docs.ceph.com/en/pacific/rados/operations/user-management/

If you want to modify it please see the "MODIFY USER CAPABILITIES" section how to do it in the above doc as Eugen suggested.

Hello,

I am trying to add my first mds service on any node. I am unable to add
keyring to start mds service.

# $ sudo ceph auth get-or-create mds.mynode mon 'profile mds' mgr
'profile
mds' mds 'allow *' osd 'allow *'

Error ENINVAL: key for mds.mynode exists but cap mds does not match
It says the key mds.mynode already exists. What's the output of the
`ceph auth ls` ?

Thanks!


I tried this command on storage nodes, admin nodes(monitor) , same
error.

ceph mds stat
cephfs:0

This makes sense I don't have any mds services running yet.

I had no problem creating keyrings for other services like monitors and
mgr.

Thanks
jerry
