OSD删除+Ceph守护服务进程+Ceph服务日志分析

# 1、性能查看
[root@node1 ceph-deploy]# ceph osd perf
osd commit_latency(ms) apply_latency(ms) 
  0                  0                 0 
  2                  0                 0 
  1                  0                 0 

# 2、模拟某块盘GG了
[root@node3 ~]# systemctl stop ceph-osd@2

# 3、out
[root@node1 ~]# ceph osd out osd.2

# 4、crush rm
[root@node1 ~]# ceph osd crush rm osd.2

# 5、rm
[root@node1 ~]# ceph osd rm osd.2     

# 6、auth rm
[root@node1 ~]# ceph osd auth rm osd.2

Ceph守护服务进程

# 1、管理所有守护进程
systemctl start ceph.target
systemctl start ceph-osd@1 

# 2、服务类型分类
systemctl start ceph-osd.target
systemctl start ceph-mon.target
systemctl start ceph-mds.target

# 3、根据id区分、主机名区分
systemctl start ceph-osd@1
systemctl start ceph-mon@node1
systemctl start ceph-mds@node2

Ceph服务日志分析

# 1、日志目录、每个守护进程对应一个log
[root@node1 ceph]# cd /var/log/ceph/
[root@node1 ceph]# ll
total 9852
