Hi, Having messed up my last RHEL6 Ceph cluster rather spectacularly I decided to build again from scratch using the latest versions of the various packages. Not having proxy access does make it more of a pfaff to deploy Ceph, but I will admit the latest version of ceph-deploy is a vast improvement to earlier versions.
That said, I did notice something. After going through the OSD prepare/activate process with ceph-deploy the last step in the "quick start" is to push the admin configuration to all the nodes using the "ceph-deploy admin <node1>..." command. Once complete the quick start documentation states that you need to check the file permissions on ceph.client.admin.keyring along with a sudo command to change the permissions to allow read access. Running the "ceph health" after this did not work and I soon discovered I had to run the same file permission command on file /etc/ceph/ceph.conf on each node as well. Only then did the "ceph health" command work and report back with a "HEALTH_OK". On the admin node itself, the configuration files prior to running the "ceph-deploy admin" command is: -rw-r--r-- 1 ceph ceph 72 Jan 27 18:34 ceph.bootstrap-mds.keyring -rw-r--r-- 1 ceph ceph 72 Jan 27 18:34 ceph.bootstrap-osd.keyring -rw-r--r-- 1 ceph ceph 64 Jan 27 18:34 ceph.client.admin.keyring -rw-r--r-- 1 ceph ceph 237 Jan 27 17:49 ceph.conf -rw-r--r-- 1 ceph ceph 54181 Jan 27 18:45 ceph.log -rw-r--r-- 1 ceph ceph 73 Jan 27 17:49 ceph.mon.keyring After running "ceph-deploy admin...." The file permissions on the nodes in /etc/ceph were as follows: -rw------- 1 root root 64 Jan 27 18:45 ceph.client.admin.keyring -rw------- 1 root root 237 Jan 27 18:45 ceph.conf -rwxr-xr-x 1 root root 92 Dec 20 22:47 rbdmap The exception to this is the admin node itself. The ceph-deploy admin command resulted in the following file permissions on the admin node in /etc/ceph -rw-r--r-- 1 root root 64 Jan 27 19:13 ceph.client.admin.keyring -rw-r--r-- 1 root root 237 Jan 27 19:13 ceph.conf There seems to be inconsistency here somewhere. Is this expected behavior?
