ceph-deploy admin command

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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?

 

Cheers

Alistair
