ULTRAM失败的磁盘的隔离和更换从Ceph/存贮的集群- vEPC
Introduction
本文描述要求的步骤实行为了查出和替换从在对象存储磁盘主机的Ceph/存贮簇的OSD磁盘(OSD) -在ULTRAM设置的估计。
背景信息
ULTRAM是设计的一个被预先包装的和被验证的虚拟化的便携信息包核心解决方案简化VNFs的配置。 OpenStack是虚拟化的基础设施管理器(精力) ULTRAM的并且包括这些节点类型：
- 估计
- OSD -估计
- 控制器
- OpenStack平台-导向器(OSPD)
ULTRAM高级体系结构和介入的组件在此镜像表示：
UltraM ArchitectureThis文件供熟悉Cisco ULTRAM平台的Cisco人员使用，并且选派要求的步骤被执行在OpenStack级别在OSPD服务器更换时。

事先需要的健康检查
1. 请使用list命令的Ceph磁盘为了了解OSD映射连接和识别将查出和被替换的磁盘。
[heat-admin@pod1-osd-compute-3 ~]$ sudo ceph-disk list
/dev/sda :
/dev/sda1 other, iso9660
/dev/sda2 other, xfs, mounted on /
/dev/sdb :
/dev/sdb1 ceph journal, for /dev/sdc1
/dev/sdb3 ceph journal, for /dev/sdd1
/dev/sdb2 ceph journal, for /dev/sde1
/dev/sdb4 ceph journal, for /dev/sdf1
/dev/sdc :
/dev/sdc1 ceph data, active, cluster ceph, osd.1, journal /dev/sdb1
/dev/sdd :
/dev/sdd1 ceph data, active, cluster ceph, osd.7, journal /dev/sdb3
/dev/sde :
/dev/sde1 ceph data, active, cluster ceph, osd.4, journal /dev/sdb2
/dev/sdf :
/dev/sdf1 ceph data, active, cluster ceph, osd.10, journal /dev/sdb4
2. 在您继续进行被识别的OSD磁盘隔离前，请验证Ceph健康和OSD树映射。

有故障的OSD磁盘隔离和删除从簇
1. 禁用并且终止OSD进程。
[heat-admin@pod1-osd-compute-3 ~]$ sudo systemctl disable ceph-osd@7
[heat-admin@pod1-osd-compute-3 ~]$ sudo systemctl stop ceph-osd@7
2. 标记OSD。
[heat-admin@pod1-osd-compute-3 ~]$ sudo su
[root@pod1-osd-compute-3 heat-admin]# ceph osd set noout
set noout
[root@pod1-osd-compute-3 heat-admin]# ceph osd set norebalance
set norebalance
[root@pod1-osd-compute-3 heat-admin]# ceph osd out 7
marked out osd.7.
3. 确认，如果OSD被标记和等待Ceph重新平衡向前进行。
[root@pod1-osd-compute-3 heat-admin]# watch -n1 ceph -s
95 active+undersized+degraded+remapped+wait_backfill
28 active+recovery_wait+degraded

22 active+undersized+degraded+remapped+wait_backfill
1 active+undersized+degraded+remapped+backfilling
8 active+undersized+degraded+remapped+wait_backfill
4. 去除OSD的认证密钥。
[root@pod1-osd-compute-3 heat-admin]# ceph auth del osd.7
updated
5. 确认OSD.7的键不是列出的。
[root@pod1-osd-compute-3 heat-admin]# ceph auth list

7. 从簇去除OSD。
[root@pod1-osd-compute-3 heat-admin]# ceph osd rm 7
removed osd.7
8. 卸载需要被替换的OSD磁盘。
[root@pod1-osd-compute-3 heat-admin]# umount /var/lib/ceph/osd/ceph-7
9. 移置noscrub和deepscrub。
[root@pod1-osd-compute-3 heat-admin]# ceph osd unset noscrub
unset noscrub
[root@pod1-osd-compute-3 heat-admin]# ceph osd unset nodeep-scrub
unset nodeep-scrub
10. 验证Ceph健康并且等待健康好和所有PG回来到active+clean。

替换OSD磁盘并且创建新的VD
1. 取消有故障的驱动并且用新的驱动替换它： Cisco UCS C240 M4服务器安装和服务指南。
2. 验证登录对CIMC OSD估计并且检查OSD在身体好被替换并且显示的slot。
3. 创建一新的HDD的一个虚拟驱动器，它必须是一新鲜的HDD，不用任何元数据。
4. 验证新加的磁盘在Unconimaged好状态。
存贮> Cisco 12G SAS模块化袭击控制器(SLOT-HBA) >物理驱动信息
5. 选择从未使用的物理推进选项的创建虚拟驱动器为了创建VD。
存贮> Cisco 12G SAS模块化袭击控制器(SLOT-HBA)
6. 请使用物理驱动9为了创建一个新的VD和命名它作为OSD3。

5. 激活Ceph磁盘并且移置noscrub并且nodeep洗刷标志位。
[root@pod1-osd-compute-3 heat-admin]# ceph-disk activate-all
[root@pod1-osd-compute-3 heat-admin]# ceph osd unset noout
