一 摘要

笨猪主要介绍ceph常见告警及维护方法或过程中遇到的问题

二 环境信息

2.1 ceph版本

[cephadmin@proceph01 ~]$ ceph -v
ceph version 14.2.15 (afdd217ae5fb1ed3f60e16bd62357ca58cc650e5) nautilus (stable)
[cephadmin@proceph01 ~]$

2.2 操作系统版本

[cephadmin@proceph01 ~]$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)
[cephadmin@proceph01 ~]$

三 常见告警及处理办法

3.1 pgs not deep-scrubbed in time

这个告警，处理过程中会引起新的告警，新的告警请忽略，过段时间会自动解除。处理过程会有点长

3.1.1 报错

[cephadmin@proceph01 ~]$ ceph health detail
HEALTH_WARN 1 pgs not deep-scrubbed in time
PG_NOT_DEEP_SCRUBBED 1 pgs not deep-scrubbed in time
    pg 1.d6 not deep-scrubbed since 2021-11-06 02:49:03.880981
处理
[cephadmin@proceph01 ~]$ ceph pg deep-scrub  1.d6
instructing pg 1.d6 on osd.17 to deep-scrub
[cephadmin@proceph01 ~]$

3.1.2 处理

[cephadmin@proceph01 ~]$ ceph pg deep-scrub  1.d6
instructing pg 1.d6 on osd.17 to deep-scrub
[cephadmin@proceph01 ~]$

处理过程 会引起新的告警，而且处理时间也不短，我这里三个节点，18块osd ，跑了2-3个小时。

[cephadmin@proceph01 ~]$ ceph health detail
HEALTH_WARN 1 pgs not deep-scrubbed in time; 10 slow ops, oldest one blocked for 52 sec, osd.17 has slow ops
PG_NOT_DEEP_SCRUBBED 1 pgs not deep-scrubbed in time
    pg 1.d6 not deep-scrubbed since 2021-11-06 02:49:03.880981
SLOW_OPS 10 slow ops, oldest one blocked for 52 sec, osd.17 has slow ops

3.1.3 处理完成

[cephadmin@proceph01 ~]$ ceph -s
