CEPH -S集群报错汇总

版权声明： https://blog.csdn.net/qq_32485197/article/details/88892264

问题一：

ceph -s

health HEALTH_WARN
            too many PGs per OSD (320 > max 300)
查询当前每个osd下最大的pg报警值：

[root@k8s-master01 ~]# ceph --show-config  | grep mon_pg_warn_max_per_osd
mon_pg_warn_max_per_osd = 300

解决方案：在配置文件中，调大集群的此选项的告警阀值；方法如下，在mon节点的ceph.conf（/etc/ceph/ceph.conf）配置文件中添加:

[root@k8s-master01 ~]# vim /etc/ceph/ceph.conf 
[global]
.......
mon_pg_warn_max_per_osd = 1000
重启monitor服务：

[root@k8s-master01 ~]# vim /etc/ceph/ceph.conf 
[root@k8s-master01 ~]# systemctl restart ceph-mon.target

[root@k8s-master01 ~]# ceph -s
