#1.添加Mon 当前ceph的状态 # ceph -s cluster f4833745-d220-407b-82ea-72eb6297d435 health HEALTH_OK monmap e3: 3 mons at {dlw1=172.16.40.11:6789/0,dlw2=172.16.40.12:6789/0,dlw3=172.16.40.13:6789/0} election epoch 14, quorum 0,1,2 dlw1,dlw2,dlw3 osdmap e26: 3 osds: 3 up, 3 in flags sortbitwise,require_jewel_osds pgmap v9695: 352 pgs, 6 pools, 45725 kB data, 20 objects 253 MB used, 584 GB / 584 GB avail 352 active+clean
当前已有三个mon，分别为dlw1，dlw2和dlw3，现在添加第四个mon dlw4
疑问：为什么要有四个mon,也不满足Paxos 算法，因为我添加了dlw4作为mon，再把dlw1的mon移除掉，这样就等同于mon迁移了...，这不是重点，重点是添加mon过程中的报错及解决办法，做个记录。
用最简单快速的方法来添加ceph-deploy
