Ceph分佈式存儲更換磁盤操做步驟

Ceph分佈式存儲更換磁盤操做步驟dom

一、確認須要更換的磁盤對應的盤符、OSD ID ;分佈式

root@Ceph-B**A**-04-S2-60:~# df -h |grep 17ide

/dev/sdp3       1.1T  566G  551G  51% /var/lib/ceph/osd/ceph-17優化

二、確認磁盤對應的槽位;spa

root@Ceph-B**A**-04-S2-60:~# ll /dev/disk/by-path/ |grep sdpcode

lrwxrwxrwx 1 root root    9 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0 -> ../../sdp進程

lrwxrwxrwx 1 root root   10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part1 -> ../../sdp1ci

lrwxrwxrwx 1 root root   10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part2 -> ../../sdp2rem

lrwxrwxrwx 1 root root   10 Aug 17 19:17 pci-0000:02:00.0-scsi-0:0:18:0-part3 -> ../../sdp3it

三、確認主機SN;

root@Ceph-B**A**-04-S2-60:~# dmidecode -s system-serial-number

HVNHB**

四、設置OSD Flag;

ceph osd out 17

五、查看集羣狀態;

ceph -s

六、關閉對應的OSD進程;

stop cep-osd id=17

七、從CrshMap中移除OSD;

ceph osd crush remove osd.17

八、刪除OSD認證信息;

ceph auth del osd.17

九、從集羣中移除OSD;

ceph osd rm 17

十、卸載掛載點;

umount /var/lib/ceph/osd/ceph-17

十一、更換新的磁盤。。。略;

 

十二、格式化新磁盤;

ceph-deploy disk zap Ceph-B**A**-04-S2-60.domain.tld:sdp

1三、建立OSD;

ceph-deploy osd create Ceph-B**A**-04-S2-60.domain.tld:sdp

1四、調整CrushMap;

ceph osd crush add osd.17 1.17 root=sata pod=sata-pod-01 chassis=sata-chassis-01 host=Ceph-B**A**-04-S2-60-sata

1五、優化掛載參數;

mount -o remount,nobarrier /var/lib/ceph/osd/ceph-17
