Linux / Ubuntu上的ZFS：在Ubuntu从13.04升级到13.10之后帮助导

我已将Ubuntu从版本13.04更新到版本13.10,但发现SATA磁盘ID已更改,我的ZFS池现已失败.

在新的Ubuntu 13.10上,磁盘ID现在是ata- *而不是scsi-SATA_ *.

这是更新后的池状态：

pool: nestpool
 state: UNAVAIL
status: One or more devices could not be used because the label is missing 
    or invalid.  There are insufficient replicas for the pool to continue
    functioning.
action: Destroy and re-create the pool from
    a backup source.

经过长时间的互联网研究,我开始遵循以下程序：

首先使用：zpool export nestpool导出池

然后尝试使用以下命令导回池：zpool import -m -f -d / dev / disk / by-id nestpool

但导入失败并显示以下消息：无法导入“nestpool”：当前无法使用一个或多个设备

这是zpool import的当前输出

pool: nestpool
     id: 3947768928242827823
  state: DEGRADED
 status: One or more devices contains corrupted data.
 action: The pool can be imported despite missing or damaged devices.  The
    fault tolerance of the pool may be compromised if imported.

        ata-Samsung_SSD_840_PRO_Series_S1ATNEAD707066K      UNAVAIL

日志分区未正确识别,它们应为ata-Samsung_SSD_840_PRO_Series_S1ATNEAD707062H-part2和ata-Samsung_SSD_840_PRO_Series_S1ATNEAD707066K-part3.而导入过程中的参数-m并没有帮助.

我找不到告诉zpool import为日志设备使用不同路径/ id的方法.任何有关解决此问题的帮助和想法将非常感激.我还能做些什么来恢复这个游泳池？

解决方法

尝试导入.也许zpool import -f nestpool

也许尝试删除不可用的日志设备：

zpool删除nestpool mirror-1

从现在开始,使用整个设备进行L2ARC和ZIL ……

编辑：

最简单的解决方法是在/ dev / disk / by-id中临时创建所需的符号链接以导入池.运行当前ZFS的RHEL系统的示例.
