Hi ... I am now testing cephfs on an ubuntu client before going back to centos. A quick question about this command: mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=admin,secretfile=/etc/ceph/admin.secret ? mount -t ceph 192.168.0.1:6789:/ /mnt/mycephfs -o name=ceph,secretfile=/etc/ceph/ceph.keyring ? Does it need admin.secret or can i use ceph.keyring to mount with cephfs file system? Just a note: At the initial setup of the cluster i used: mkcephfs -c /etc/ceph/ceph.conf --mkfs -a -k /etc/ceph/ceph.keyring. So i only have ceph.keyring NOT admin.secret .... if i do: #mount -t ceph 172.16.0.25:6789:/ /mnt/mycephfs mount error 22 = Invalid argument #dmesg [ 7182.027665] libceph: client0 fsid 31c4d83e-cb0a-4fed-ab6f-581e8d5356f5 [ 7182.027715] libceph: no secret set (for auth_x protocol) [ 7182.027719] libceph: error -22 on auth protocol 2 init #mount -t ceph 172.16.0.25:6789:/ /mnt/mycephfs -o name=ceph,secretfile=/etc/ceph/ceph.keyring secret is not valid base64: Invalid argument. adding ceph secret key to kernel failed: Invalid argument. failed to parse ceph_options #dmesg [ 7639.377337] libceph: client0 fsid 31c4d83e-cb0a-4fed-ab6f-581e8d5356f5 [ 7639.378047] libceph: auth method 'x' error -1 Regards, Femi On Wed, Feb 6, 2013 at 4:29 PM, Dimitri Maziuk <dmaziuk@xxxxxxxxxxxxx> wrote: > On 2/6/2013 5:54 AM, Dennis Jacobfeuerborn wrote: > ... > >>> To mount cephfs like that you need to have kernel support.
