1.查看當(dāng)前集群full以及nearfull的設(shè)置值,在Mon節(jié)點(diǎn)查詢(xún)Mon配置?
ceph --admin-daemon ?/run/ceph/ceph-mon.IP.asok config show | grep full_ratio?
2.查看當(dāng)前集群full以及nearfull的設(shè)置值,在其他節(jié)點(diǎn)查詢(xún)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，并且存儲(chǔ)不能寫(xiě)入數(shù)據(jù)了，緊急配置步驟?
1）設(shè)置OSD禁止讀寫(xiě)?
ceph osd pause?
2）通知Mon修改nearfull及full的閾值?
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的閾值?
ceph pg set_nearfull_ratio 0.96?
ceph pg set_full_ratio 0.97?
4）解除OSD的禁止讀寫(xiě)?
ceph ?osd unpause?
5）整理集群，刪除一些無(wú)用的數(shù)據(jù)，擴(kuò)容集群?
6）還原集群的默認(rèn)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?
