标签:扩容 步骤 设置 阈值 unp 整理 读写 并且 near
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
