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_ *.@H_502_3@
这是更新后的池状态：@H_502_3@
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.

经过长时间的互联网研究,我开始遵循以下程序：@H_502_3@
首先使用：zpool export nestpool导出池@H_502_3@
然后尝试使用以下命令导回池：zpool import -m -f -d / dev / disk / by-id nestpool@H_502_3@
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@H_502_3@

status: One or more devices contains corrupted data.

fault tolerance of the pool may be compromised if imported.

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.@H_502_3@
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？@H_502_3@
解决方法
请尝试zpool列表.这将显示池是否可用于系统.
尝试导入.也许zpool import -f nestpool@H_502_3@
zpool删除nestpool mirror-1@H_502_3@
从现在开始,使用整个设备进行L2ARC和ZIL ……@H_502_3@
编辑：@H_502_3@
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.@H_502_3@
