Anyone,
We’ve ceph clients that we want to let mount two cephfs from each their own ceph clusters.
Both cluster are standard created w/ceph-deploy and possible only has knowledge of each their client.admin.
How could we allow a new client id to access the 2. cluster eg. as admin2?
On ceph client nodes we have this:
## used for cluster 1
# ceph-authtool -l /etc/ceph/ceph.client.admin.keyring
[client.admin]
key = AQCv5...==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"
## this entry in /etc/fstab allows us to mount from cluster 1:
none /var/lib/ceph/backup fuse.ceph ceph.id=admin,_netdev,defaults,noatime 0 0
## used for cluster 2 we’ve added a new client.admin2 on the clients’ keyring only though
# ceph-authtool -l /etc/ceph/ceph.client.admin2.keyring
[client.admin]
key = AQCao...==
caps mds = "allow *"
caps mgr = "allow *"
caps mon = "allow *"
caps osd = "allow *"
[client.admin2]
key = AQDfv...==
caps mds = "allow"
caps mon = "allow r"
caps osd = "allow rw pool data"
## this entry of /etc/fstab should point to another monitor and use admin2 fo rid so not to clash on socket file of cluster 1
node1.ceph /var/lib/ceph/backup2 fuse.ceph ceph.id=admin2,_netdev,defaults,noatime 0 0
## Only it fails to mount from cluster 2 w/Operation not supported, assume it’s because cluster 2 doesn’t know the id ‘admin2’
# mount -t ceph node1.ceph:6789:/ /var/lib/ceph/backup2 -o name=client.admin,secret=“AQCao...=="
mount error 1 = Operation not permitted
# mount -t ceph node1.ceph:6789:/ /var/lib/ceph/backup2 -o name=client.admin2,secret=“AQDfv...=="
mount error 1 = Operation not permitted
How to debug/remediate/solve this?
TIA
