Bug #12458
Updated by Kefu Chai almost 9 years ago
environment:centos7+ceph v0.87 problem: # 1, the function do_map() in /etc/init.d/rbdmap will do post-mapping checking after mapped a new image, but the directory /etc/ceph/rbd.d/ doesn't exist at all and isn't created automaticall. Therefore, the “rbdmap” sctrip failed to do post-mapping checking. # 2. In /etc/ceph/rbdmap, auth parameter "id=client,keyring=/etc/ceph/ceph.client.keyring" is not correct, and it should be "id=admin,keyring=/etc/ceph/ceph.client.admin.keyring", user without "client." prefix. # 3. the parameter "--keyfile" cant't be used when map a rbd, and it can be replaced by "--keyring". There is no description of "--keyring" in the helping info of "rbd -h". <pre> [root@c8 src]# rbd map im1 --id admin --keyfile /etc/ceph/ceph.client.admin.keyring rbd: failed to get secret rbd: map failed: (22) Invalid argument 2015-07-24 23:27:03.415795 7f585deaf880 -1 auth: failed to decode key '[client.admin] key = AQByfqZVOAGSAhAAGnjXsO2WZpK1qT7ZNQ9IgA== auid = 0 caps mds = "allow" caps mon = "allow *" caps osd = "allow *" [root@c8 src]# rbd map im1 --id admin --keyring /etc/ceph/ceph.client.admin.keyring /dev/rbd2 [root@c8 src]# rbd -h |grep keyring [root@c8 src]# </pre>
