Hi Jean,
Here is the output for ceph auth list for client.cinder
client.cinder
key: AQCKaP9ScNgiMBAAwWjFnyL69rBfMzQRSHOfoQ==
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx
pool=volumes, allow rx pool=images
Here is the output of ceph -s:
ashish@ceph-client:~$ ceph -s
cluster afa13fcd-f662-4778-8389-85047645d034
health HEALTH_OK
monmap e1: 1 mons at {ceph-node1=10.0.1.11:6789/0}, election epoch 1,
quorum 0 ceph-node1
osdmap e37: 3 osds: 3 up, 3 in
pgmap v84: 576 pgs, 6 pools, 0 bytes data, 0 objects
106 MB used, 9076 MB / 9182 MB avail
576 active+clean
I created all the keyrings and copied as suggested by the guide.
