Hi,
I have a doubt in mapping rbd using client keyring file. Created keyring as
below
sudo ceph-authtool -C -n client.foo --gen-key /etc/ceph/keyring
sudo chmod +r /etc/ceph/keyring
sudo ceph-authtool -n client.foo --cap mds 'allow' --cap osd 'allow rw
pool=pool1' --cap mon 'allow r' /etc/ceph/keyring
sudo ceph-authtool -l /etc/ceph/keyring
sudo ceph -k /etc/ceph/ceph.client.admin.keyring auth add client.foo -i
/etc/ceph/keyring
root@client1:~$ sudo cat /etc/ceph/keyring
[client.foo]
key = AQDkeSlUWGa6ExAAf2T/S6kJdQtRJqNoovinWw==
caps mds = "allow"
caps mon = "allow r"
caps osd = "allow r pool=pool1"
I tried mapping rbd and got following error message
root@client1:~$ sudo rbd map img1 -p pool1 -n client.foo -k /etc/ceph/keyring
2014-10-01 21:37:43.404051 7f3858d4a840 2 auth: KeyRing::load: loaded key file
/etc/ceph/keyring
rbd: sysfs write failed
rbd: map failed: (34) Numerical result out of range
How to map an rbd after setting read-only permission for particular pool ?
How to run or perform read IO for particular pool ?
