Thanks for your help!!
But I have the other question:
If I do "/etc/init.d/ceph -a stop "
the system doesn't stop all the deamon which include cmon and cosd.
Therefore I have to enter each host to close the deamon seperatly.
Finally, there is no deamon running in the system.
I want to know why we cannot stop the deamon by "/etc/init.d/ceph -a stop "???
What's wrong with my system??
The ceph.conf as shown below:
[global]
pid file = /var/run/ceph/$name.pid
debug ms =1
auth supported = cephx
[mon]
mon data = /data1/mon$id
;debug ms = 1
;debug mon = 20
;debug paxos = 20
;debug auth = 20
[mon0]
host = Ceph1
mon addr = 192.168.200.201:6789
[mon1]
host = Ceph2
mon addr = 192.168.200.202:6789
[mon2]
host = Ceph3
mon addr = 192.168.200.203:6789
[mds]
keyring = /etc/ceph/keyring.$name
;debug ms = 1
;debug mds = 20
[mds0]
host = Ceph4
[mds1]
host = Ceph5
[osd]
keyring = /etc/ceph/keyring.$name
osd data = /mnt/btrfs/osd$id
osd journal = /opt/osd/osd$id/journal
;osd journal = /data/osd$id/journal
osd journal size = 512
;debug ms = 1
;debug osd = 20
;debug filestore = 20
;debug journal = 20
[osd0]
host = Ceph6
btrfs devs = /dev/sdb1
[osd1]
host = Ceph6
btrfs devs = /dev/sdc1
[osd2]
host = Ceph6
btrfs devs = /dev/sdd1
[osd3]
host = Ceph7
btrfs devs = /dev/sdb1
[osd4]
host = Ceph7
btrfs devs = /dev/sdc1
[osd5]
host = Ceph7
btrfs devs = /dev/sdd1
