Hi Jean, If you do not want to use the admin user, which is the most logical thing to do, you must create a client with rbd access to the pool on which you are going to perform the I/O actions. For example in our case it is the user cinder: client.cinder key: XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX caps: [mgr] allow r caps: [mon] profile rbd caps: [osd] profile rbd pool=vol1, profile rbd pool=vol2 ..... profile rbd pool=volx And the install the client keyring on the client node: cephclient:~ # ls -la /etc/ceph/ total 28 drwxr-xr-x 2 root root 4096 Jul 18 11:37 . drwxr-xr-x 132 root root 12288 Jul 18 11:37 ... -rw-r--r-- 1 root root root 64 Oct 19 2017 ceph.client.cinder.keyring -rw-r--r-- 1 root root root 2018 Jul 18 11:37 ceph.conf In our case we have added cat /etc/profile.d/ceph-cinder.sh export CEPH_ARGS="--keyring /etc/ceph/ceph.client.cinder.keyring --id cinder" so that it picks it up automatically- cephclient:~ # rbd ls -p volumes image01_to_remove volume-01bbf2ee-198c-446d-80bf-f68292130f5c volume-036865ad-6f9b-4966-b2ea-ce10bf09b6a9 volume-04445a86-a032-4731-8bff-203dfc5d02e1 ...... I hope this help you. Cheers, I _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
