（请注意，当我返回服务器时，我将使用 zpool status 进行修改以便更清楚）
我有一个 6x2TB 磁盘 raidz2 ZFS 池，托管在 Solaris 11 中
我两年前构建此服务器时安装的原始 M1015（刷新至 IT 模式）发生故障，无法再在 PCI-E 总线上识别。我昨天用另一个 M1015（刷新至 IT 模式）替换了它，Solaris 再次找到了所有磁盘。
但是，ZFS 池被置于 SUSPENDED 模式（可能是因为之前的 M1015 在运行时死亡并且之前所有的磁盘都消失了），我看到 2 个磁盘上正在重新镀银（？？），所有磁盘都被列为不可用。
我毫不怀疑池中存在一些错误。但我已经清除了（fmadm 已修复，zpool 已清除）故障，希望池可以在降级状态下重新挂载。然而，重新启动后，池首先显示为降级（一些磁盘显示为不可用，一些显示为降级），然后立即转换为暂停，所有磁盘都显示为不可用，并开始重新同步。
重新同步速度从大约 100MBps 开始，然后迅速下降到 50kbps 或更低。这相当于预计的重新同步时间有几百个小时。更重要的是，iostat 显示池中的任何磁盘上都没有发生任何事务。似乎所有事务都在重启后不久突然发生，因为我可以看到在连续重启后大约 +1GB 的扫描进度。
当池处于挂起状态时，我无法脱机任何磁盘或导出池（此外，当“fmadm 故障”条目全部报告为已修复时，我也不确定为什么它会进入挂起状态）
更换 SAS 控制器时我哪里出了问题？如何恢复？
