V440做raid1出现needs maintenance

陈小坑

有一台V440，用sds做的raid1
# metastat
d0: Mirror
    Submirror 0: d10
      State: Needs maintenance
    Submirror 1: d20
      State: Needs maintenance
    Pass: 1
    Read option: roundrobin (default)
    Write option: parallel (default)
    Size: 32054400 blocks

d10: Submirror of d0
    State: Needs maintenance
    Invoke: metareplace d0 c1t0d0s0 <new device>
    Size: 32054400 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Hot Spare
        c1t0d0s0                   0     No    Maintenance  


d20: Submirror of d0
    State: Needs maintenance
    Invoke: after replacing "Maintenance" components:
                metareplace d0 c1t1d0s0 <new device>
    Size: 32054400 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Hot Spare
        c1t1d0s0                   0     No    Last Erred   

在CU中看到有tx处理过类似的问题，于是在做好系统备份后，我用以下命令去修复镜像
# metareplace -e d0 c1t0d0s0
修复完成后出现如下状态
# metastat
d0: Mirror
    Submirror 0: d10
      State: Needs maintenance
    Submirror 1: d20
      State: Needs maintenance
    Pass: 1
    Read option: roundrobin (default)
    Write option: parallel (default)
    Size: 32054400 blocks

d10: Submirror of d0
    State: Needs maintenance
    Invoke: metasync d0
    Size: 32054400 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Hot Spare
        c1t0d0s0                   0     No    Resyncing    


d20: Submirror of d0
    State: Needs maintenance
    Invoke: after replacing "Maintenance" components:
                metareplace d0 c1t1d0s0 <new device>
    Size: 32054400 blocks
    Stripe 0:
        Device              Start Block  Dbase State        Hot Spare
        c1t1d0s0                   0     No    Last Erred

请问各位大侠，接下来该如何做啊？是重启一下还是直接调用metasync d0?谢谢

v440是可以做硬raid1的，有可能是硬盘挂了。format看看

陈小坑

从表象来看，硬盘没坏。需要再检测磁盘坏道吗？

晕二楼的，别人是用sds做的raid1，不要想当然教条的说V440是硬raid

现检查d20(c1t1d0s0)是不是有问题（比如坏道之类的），做之前先备份。
metasync d0
如果d20坏了，则需要换盘
metareplace -e d20 c1t1d0s0

陈小坑

好象有报错的，接下来该怎么办啊？

换这个磁盘吧！

陈小坑

好的。那么现在这个状态下，我应该怎么再操作呢？是先重启动呢？还是做metasync d0？

好像c1t0d0也命不长。

现在最好不要重启，先把镜像拆掉，从c1t0d0启动主机。。。。
