今天有客户反映有VPS非常慢,检查发现是x124物理服务器的一块硬盘有故障,RAID已经是单硬盘在运行,Linux日志报告sdb不支持SMART:
[root@x124 ~]# grep sdb /var/log/messages
Jan 30 04:12:14 x124 smartd[2928]: Device: /dev/sdb, not capable of SMART self-check
Jan 30 04:12:14 x124 smartd[2928]: Device: /dev/sdb, failed to read SMART Attribute Data
Jan 30 04:42:14 x124 smartd[2928]: Device: /dev/sdb, not capable of SMART self-check
Jan 30 04:42:14 x124 smartd[2928]: Device: /dev/sdb, failed to read SMART Attribute Data
Jan 30 05:12:13 x124 smartd[2928]: Device: /dev/sdb, not capable of SMART self-check
Jan 30 05:12:13 x124 smartd[2928]: Device: /dev/sdb, failed to read SMART Attribute Data
于是拔出sdb,换了一块新硬盘,重建RAID。硬盘都是热插拔的,整个过程服务器没有中断,服务器上所有的VPS都没有中断,正常运行。RAID重建需要几十个小时,在此过程中VPS可能会感觉IO比较慢,RAID重建完成就好了。
