红帽全球峰会4.6. 为 Ceph Manager 打开端口
ceph-mgr 守护进程从与 ceph-osd 守护进程相同的端口范围的 OSD 接收 PG 信息。如果没有打开这些端口，集群将从 HEALTH_OK 转移到 HEALTH_WARN，并且指示 PG 为 unknown，其百分比数为 unknown。
要解决这种情况，在每个运行 ceph-mgr 守护进程的主机中，打开端口 6800:7300。例如：
[root@ceph-mgr] # firewall-cmd --add-port 6800:7300/tcp [root@ceph-mgr] # firewall-cmd --add-port 6800:7300/tcp --permanent
[root@ceph-mgr] # firewall-cmd --add-port 6800:7300/tcp
[root@ceph-mgr] # firewall-cmd --add-port 6800:7300/tcp --permanent
然后，重启 ceph-mgr 守护进程。
