ZFS:如何查找已分离的磁盘？
ZFS:如何查找已分离的磁盘？
提问于 2016-07-26 22:49:46
我的ZFS池中有两个发生故障的磁盘，我用zpool replace的热备盘替换了它们。如何识别出现故障的磁盘，以便可以实际更换它们？
下面是我在损坏的磁盘上运行zpool detach之前和之后的zpool status输出。
在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

您需要确定您的控制器和盘柜托架。对于服务器上的FreeBSD，this answer似乎是有帮助的。如果您有LSI SAS控制器，则可以找到带有sas2ircu和磁盘序列号的存储模块(如果存储模块支持的话，还可以闪烁存储模块)。
将来，我建议在配置管理数据库中(或仅在一张纸上)写下磁盘供应商、类型、序列号、盘柜名称/编号和控制器名称/端口，因为不必查找会更快，尤其是对于大型阵列。
在FreeBSD上，也可以使用WWN (全球通用名称)来命名磁盘，而不是使用编号的da0、da1、...这意味着您可以直接看到哪个磁盘有问题，然后使用简单的Ctrl+C/Ctrl+F查找它们。当然，如果您愿意，也可以编写脚本。
