Ceph存储池full等处理方式

1.查看当前集群full以及nearfull的设置值,在Mon节点查询Mon配置 
ceph --admin-daemon  /run/ceph/ceph-mon.IP.asok config show | grep full_ratio 
2.查看当前集群full以及nearfull的设置值,在其他节点查询osd配置 
ceph --admin-daemon  /run/ceph/ceph-osd.0.asok config show | grep full 
3.遇到集群full的告警，并且存储不能写入数据了，紧急配置步骤 
1）设置OSD禁止读写 
ceph osd pause 
2）通知Mon修改nearfull及full的阈值 
ceph tell mon.* injectargs "--mon-osd-nearfull-ratio 0.96" 
ceph tell mon.* injectargs "--mon-osd-full-ratio 0.97" 
ceph tell osd.* injectargs "--mon-osd-nearfull-ratio 0.96" 
ceph tell osd.* injectargs "--mon-osd-full-ratio 0.97" 
3）通知pg修改nearfull及full的阈值 
ceph pg set_nearfull_ratio 0.96 
ceph pg set_full_ratio 0.97 
4）解除OSD的禁止读写 
ceph  osd unpause 
5）整理集群，删除一些无用的数据，扩容集群 
6）还原集群的默认配置 
ceph tell mon.* injectargs "--mon-osd-nearfull-ratio 0.85" 
ceph tell mon.* injectargs "--mon-osd-full-ratio 0.95" 
ceph tell osd.* injectargs "--mon-osd-nearfull-ratio 0.85" 
ceph tell osd.* injectargs "--mon-osd-full-ratio 0.95" 
ceph pg set_nearfull_ratio 0.85 
ceph pg set_full_ratio 0.95
