ceph 之 mon quorum操作

取消某个mon的法人资格：

# ceph tell mon.ceph-test-3 quorum exit
stopped responding to quorum, initiated new election

1 2	# ceph tell mon.ceph-test-3 quorum exit stopped responding to quorum, initiated new election

恢复一个mon的法人资格

# ceph tell mon.ceph-test-3 quorum enter

1	# ceph tell mon.ceph-test-3 quorum enter

不幸的是，该命令卡死不动；甚至，如果期望提示enter补全都会卡死不动; 哪怕是4个mon，exit一个再tell回来也是卡死的，所以，tell命令似乎只能取消法人资格，不能恢复法人资格

方法2：直接在需要恢复法人资格的daemon上执行如下命令

# ceph daemon mon.ceph-test-3 quorum enter
started responding to quorum, initiated new election

1 2	# ceph daemon mon.ceph-test-3 quorum enter started responding to quorum, initiated new election
