Tks, but it still not works well. I find that there is something wrong happens when run command:
mkcephfs -a -c /etc/ceph/ceph.conf -k /etc/ceph/keyring.admin –mkfs
And the result is as follows:

[root@test-a ceph]# mkcephfs -a -c /etc/ceph/ceph.conf -k /etc/ceph/keyring.admin

My ceph.conf is :
[global]
    max open files = 131072
    keyring = /etc/ceph/keyring.admin

#####MON#####
[mon]
    mon data = "">
[mon.0]
    host = test-a
    mon addr = 10.239.82.163:6789
[mon.1]
    host = test-b
    mon addr = 10.239.82.95:6789
#####MDS#####
[mds]
keyring = /etc/ceph/keyring.$name

what is the problem in my settings?

You need to add [mon.NAME] in the configuration file.

Example:

[mon.kvm01]

mon_addr = 
192.168.100.1:6789

host = kvm01

[mon.kvm03]

mon_addr = 
192.168.100.3:6789

host = kvm03

[mon.kvm02]

mon_addr = 
192.168.100.2:6789

host = kvm02

But I have put the ceph.conf in the directory /etc/ceph/. How can I resolve it?

Hi,

         I encounter a problem when startup the ceph cluster.
         When run the command: service ceph -a start,

The process always hang up. The error result is: 

[root@test-c ceph]# service ceph -a start

=== mon.0 ===

Starting Ceph mon.0 on test-c...

failed: 'ulimit -n 131072;  /usr/bin/ceph-mon -i 0 --pid-file /var/run/ceph/mon.0.pid -c /etc/ceph/ceph.conf '

Starting ceph-create-keys on test-c...

=== mon.1 ===

Starting Ceph mon.1 on test-d...

global_init: unable to open config file from search list /etc/ceph/ceph.conf

failed: 'ssh test-d ulimit -n 131072;  /usr/bin/ceph-mon -i 1 --pid-file /var/run/ceph/mon.1.pid -c /etc/ceph/ceph.conf '

Starting ceph-create-keys on test-d...

The process hangs and wait. Anybody know the reason for these? And how can I solve such problem?
