2. 查看该对象对应的pg号以及osd组: [root@node1 ~]# ceph osd map testpool test.txtosdmap e76 pool'testpool'(2) object'test.txt'-> pg 2.8b0b6108 (2.8) -> up ([1,2,0], p1) acting ([1,2,0], p1) 3. 踢除主osd,pg降级,次osd升级为临时主osd: [root@node2 ~]# systemctl s...
降级就是在发生了一些故障比如OSD挂掉之后,ceph将这个OSD上的所有PG标记为degraded,但是此时的集群还是可以正常读写数据的,降级的PG只是相当于小感冒而已,并不是严重的问题,而另一个词undersized,我的理解就是当前存活的PG 0.44数为2,小于副本数3,将其做此标记,也不是严重的问题。 Peered 那么,什么才是PG的大病...
PG(Placement Group)是Ceph中一个非常关键的概念,它是一组OSD(对象存储设备)的逻辑分组。PG负责数据的分布和可靠性保证。在Ceph集群中,每个对象都属于一个PG,并且由这个PG的OSD组负责存储和处理。 当我们遇到“ceph pg_degraded”问题时,意味着一个或多个PG的健康状态受到了损害。一种常见的情况是,某个OSD发生故...
The output ofceph health detailshows "OSD_TOO_MANY_REPAIRS": Too many repaired reads on 1 OSDs along with "PG_DEGRADED" and "SLOW_OPS". Example: Raw [root@edon-00 ~]# ceph health detail HEALTH_WARN Too many repaired reads on 1 OSDs; Degraded data redundancy: 1/104988123404 objects deg...
创建pool 时,副本数 设置为 非1 时,会出现 "degraded" 告警信息 2、pg归置组异常状态 pg归置组异常,目前主要分为两种情况 1) 单节点的时候pg归置组 unclean 或者 degraded 2) 多个节点的时候pg归置组 unclean 或者 degraded 3、单节点 pg归置组

'ceph osd reweight-by-utilization' was used in an attempt to help re-balance data on over-utilized OSD's throughout the cluster. After the data was re-balanced and the cluster settled down, Placement Groups can be seen stuck unclean and remapped with objects in a degraded state. ...
PG状态的含义 PG的非正常状态说明可以参考[2],undersized与degraded的含义记录于此: undersized The placement group has fewer copies than the configured pool replication level. degraded Ceph has not replicated some objects in the placement group the correct number of times yet. ...
