monitor failover of ceph

["=?gb18030?b?t8k=?=" <duron800@xxxxxx>]

hello, I am a new user of ceph,

I have built a ceph testing Environment for block storage,

I have 2 osd and 2 monitor,In addition to failover test, other tests are normal.

when I perform failover test, if I stop one osd , the cluster is OK,

but if I stop one monitor , the cluster have entire die , why ? thank you.

my configure file :

; global

[global]

 ; enable secure authentication

 ; auth supported = cephx

 

 auth cluster required = none

 auth service required = none

 auth client required = none

 

 mon clock drift allowed = 3

 

;  monitors

;  You need at least one.  You need at least three if you want to

;  tolerate any node failures.  Always create an odd number.

[mon]

 mon data = "">

 ; some minimal logging (just message traffic) to aid debugging

 debug ms = 1

[mon.0]

 host = sheepdog1

 mon addr = 192.168.0.19:6789

 

[mon.1]

 mon data = "">

        host = sheepdog2

        mon addr = 192.168.0.219:6789

 

; mds

;  You need at least one.  Define two to get a standby.

[mds]

 ; where the mds keeps it's secret encryption keys

 keyring = /home/ceph/keyring.mds.$id

[mds.0]

 host = sheepdog1

; osd

;  You need at least one.  Two if you want data to be replicated.

;  Define as many as you like.

[osd]

; This is where the btrfs volume will be mounted.      

 osd data = "">

 osd journal = /home/ceph/osd.$id/journal

 osd journal size = 512

 ; working with ext4

 filestore xattr use omap = true

 

 ; solve rbd data corruption

 filestore fiemap = false

[osd.0]

        host = sheepdog1

        osd data = "">

        osd journal = /var/lib/ceph/osd/diskb/journal

[osd.2]

 host = sheepdog2

 osd data = "">

 osd journal = /var/lib/ceph/osd/diskc/journal
