ceph提示: non-power-of-two pg_num解决办法

问题:   [root@cluster]# ceph -s   cluster:     id:     e7a3be6e-2e30-49fd-99c0-dbb304ae1a82     health: HEALTH_WARN             1 pool(s) have non-power-of-two pg_num

解决办法   增加OSD , ceph 空间资源不足，所致！

现在每个node 增加了一个OSD   [root@ cluster]# lsblk   sdc                                                                          8:32   0   30G  0 disk

ZAP disk  osd 清理磁盘数据   [root@ cluster]# ceph-deploy disk zap node-10 /dev/sdc

添加OSD   [root@ cluster]# ceph-deploy osd create node-10 --data /dev/sdc

检查状态   [root@ cluster]# ceph -s   cluster:     id:     e7a3be6e-2e30-49fd-99c0-dbb304ae1a82     health: HEALTH_OK
