打开印第安纳州 oi_151a7。 zpool 具有 15x 1TB raidz3 + 2x 8 磁盘 2TB raidz2。
许多磁盘操作（例如 zpool status、创建新的 iSCSI 卷（使用 sbdadm）等）都会挂起。使用 iostat (-xne)，我可以确定两个块设备有错误，一个很可能是 cdrom、软盘等，另一个是 2TB 磁盘（属于 zpool 组成的 raidz2 vdev 之一）。
iostat -xne
0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0 0 0 1344 22 1366 c10t32d0

“c9t5000C50057CEF65Fd0”的问题是它没有在“格式”中列出。 “format”进一步列出了所有 16 个 2TB 磁盘，而 iostat 列出了 17 个。其中一个 2TB 磁盘在 2-3 个月前被更换，所以我认为 iostat 可能仍然认为它存在，尽管它不存在。让我指出，我知道主机中有 16 个 2TB 物理磁盘，vdev 中有 16 个（作为 2x8 磁盘 raidz2）。
这是一个用于备份的节点，因此虽然肯定可以重新启动，但能够进一步研究它会非常方便。
iostat 和完整格式：

答案1
这是对一个非常古老的问题的简短回答，可能已经不再是问题，或者您根本不再关心。因为我遇到了同样的问题并找到了解决方案，所以我想我会在这里回答。
这很简单。添加
myIPaddress myhostname myhostname.FullyQualifiedDomainNameIFIHaveone
进入 /etc/hosts 文件，因为由于某种原因，它在查找执行操作时会查找解析器库zpool status -v
pool: vmpool03
state: ONLINE
scan: scrub repaired 0 in 0h0m with 0 errors on Fri Dec 16 23:46:02 2016

就我而言，差异在于添加 IP 和外部地址之前 4 分钟直至完成，以及之后不到一秒的时间。
