我的ZFS池中有两个发生故障的磁盘,我用zpool replace替换了热备件。如何识别故障磁盘,以便我可以实际替换它们?

以下是我在损坏的磁盘上运行zpool status之前和之后zpool detach的输出。

zpool detach之前:

  pool: mypool
 state: DEGRADED
status: One or more devices is currently being resilvered.  The pool will
        continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
  scan: resilver in progress since Tue Jun  7 11:26:56 2016
        123M scanned out of 91,8T at 5,84M/s, (scan is slow, no estimated time)
        5,23M resilvered, 0,00% done

您需要识别控制器和机箱托架。对于ServiceBSault上的FreeBSD this answer似乎很有帮助。如果您有LSI SAS控制器,则可以找到带有sas2ircu的机箱和磁盘的序列号(如果机箱支持,则闪烁机箱)。

对于未来,我建议在配置管理数据库(或只是在一张纸上)记下磁盘供应商,类型,序列号,机箱名称/编号和控制器名称/端口,因为它更快不必查阅,特别是对于大型阵列。

在FreeBSD上也可以使用WWN(全球通用名称)而不是编号为da0,da1,...来命名磁盘。这意味着您可以直接查看哪个磁盘有问题,然后使用简单的Ctrl查找它们+ C / Ctrl + F。当然,如果你愿意,也可以编写脚本。
