Open Stack

Hi guys.

  I am setting up OpenStack with Gnocchi with ceph as the storage backend,
after service gnocchi-metricd start, it always reported "PermissionError:
Failed to operate read op for oid measure", seems at the time metricd
start, it tried to list the measure object, however, there is none such
object, so does the permission show error? I didn't find any bug related,
could anyone help to tell me what am I missing? Thanks.

### ceph pools
[root at node-4 gnocchi]# rados lspools
rbd
images
volumes
compute
backups
metrics
### gnocchi pool(metrics) has none objects
[root at node-4 gnocchi]# rados ls -p metrics
[root at node-4 gnocchi]#

### /etc/gnocchi/gnocchi.conf
[storage]
driver = ceph
ceph_pool = metrics
ceph_username = gnocchi
ceph_keyring = /etc/ceph/ceph.client.gnocchi.keyring
ceph_conffile = /etc/ceph/ceph.conf

### ceph auth
client.gnocchi
key: AQAE9FtZussoMRAAiKk4lCX21k9DTDf39AE4Cg==
caps: [mon] allow r
caps: [osd] allow class-read object_prefix rbd_children, allow rwx
pool=metrics,
