我将我的服务器(SuperMicro X11-SSM-F，LSISA9911-8i)从Ubuntu18.04升级到20.04。服务器有2个zpool，一个由单个WD Red 10 TB (下载池)组成，另一个由8 WD Red 10 TB和2 Seagate IronWolf 8TB组成，配置在5x2个镜像(主池)中。池是使用/dev/disk/by-id引用创建的，以便在重新启动时保持稳定。泳池定期清洗，最后一次清洗是几周前的，没有出现任何错误。

当我更新到Ubuntu20.04后重新启动时，第二个池(主池)就消失了。在运行zfs import之后，它会重新导入它，但是对大多数磁盘( WD，而不是Seagates)使用sdX引用。此外，与单一的WD的池是好的，并参考它的磁盘按-id。母版池的zpool status输出如下(这是内存中的)：

这并不理想，因为这些标识符不稳定，所以在稍微在线查看之后，我重新导出了池，并运行了zpool import -d /dev/disk/by-id masterpool。

但现在，兹普尔告诉我，存在校验和错误：

因此，我正在运行一个检查点，zfs还发现了一些校验和错误：

  pool: masterpool
 state: DEGRADED
status: One or more devices has experienced an unrecoverable error.  An
        attempt was made to correct the error.  Applications are unaffected.
action: Determine if the device needs to be replaced, and clear the errors
        using 'zpool clear' or replace the device with 'zpool replace'.

奇怪的是，smart one在智能监控数据中没有显示任何错误(两个磁盘的输出相似，只显示一个)：

因此，这引发了许多问题：

1)为什么我的泳池不见了？这是因为/dev/disk/by-id/中的符号链接消失了，而zfs无法定位大部分磁盘吗？

2)校验和错误是否令人担忧？磁盘看起来很健康。在用sdX引用导入池时，我只查看了几个目录和文件，如果zfs以错误的顺序导入磁盘，这会导致校验和被错误地重写吗？

3)如何找回丢失的/dev/disk/by-id/ata-*符号链接？Ubuntu20.04有什么变化会导致他们消失吗？

4)我认为通过/dev/disk/by-id/引用我的磁盘是个好主意，因为它们是稳定的。这不是最好的办法吗？

5)我不喜欢wwn-*的名字，因为它们对我来说是非描述性的。我更希望有反映磁盘序列号的名称，这样，如果需要进行替换，我就可以很容易地识别它们。我继续在/dev/disk/by-vdev/中设置别名(别名为wwn-*)，遵循http://kbdone.com/zfs-basics/#Consistent_设备_ID_通过_vdev_idconf_文件中的建议：

$ cat /etc/zfs/vdev_id.conf
alias ST8000VN0022-2EL_ZA17H5D3 /dev/disk/by-id/wwn-0x5000c500a2edebe0
alias ST8000VN0022-2EL_ZA17FZXF /dev/disk/by-id/wwn-0x5000c500a2e631c6
alias WD100EFAX-68_2YG1R7PD /dev/disk/by-id/wwn-0x5000cca273c0c7e3
alias WD100EFAX-68_2YK9BHKD /dev/disk/by-id/wwn-0x5000cca273ee8907
...

有什么想法？

谢谢!

我也有同样的问题。你的职位帮助我朝着正确的方向前进。这就是我的想法。

我有6个驱动器，2个驱动器在zfs池'A‘连接到SATA控制器的主板，和4个驱动器在zfs池'B’连接到我的LSI SAS 9211控制器。安装程序在/dev/disk/by-id中查找设备的池。

在从Ubuntu18.04升级到Ubuntu20.04之后，所有附在SAS控制器上的磁盘的设备id从设备id ata-*升级到scsi-SATA*。重新启动服务器后，zfs池B丢失，因为zfs在导入期间找不到设备id。与主板上的SATA控制器连接的驱动器的设备id保持不变。使用这些驱动器的zfs池可以导入，并且在版本升级后不会丢失。

我就是这样把丢失的“B”池修好的：

首先，我列出了可以导入的所有池：

sudo zpool import

它列出了我丢失的池'B'，以及池中所有正确的驱动器，但在/dev中被命名为设备。因此，我使用/dev/disk/by-id中列出的设备id导入了池。我收到了一个警告，这个池看起来可能是活动的，所以我不得不使用-f强制导入，如下所示：

sudo zpool import -f -d /dev/disk/by-id B

一切都好起来了。B池又可用了。我没有出口游泳池。在导入池时，我没有告诉您先使用设备id。现在使用的设备id是不同的: wwn-*

我在泳池上做了个擦洗，没有出错。

回答你的问题：

我认为从Ubuntu18.04升级到20.04会导致/dev/disk/by-id中的链接发生变化。
我没有使用/dev引用导入池，而是使用选项-f导入。这就是你和我所做的不同之处。但我无法想象这会是一个问题，除非错误的驱动器在哪里使用。
我没有通过id链接把旧磁盘拿回来。但是，通过使用指令导入池来使用磁盘id，它使用的是新的磁盘id，这对我来说已经足够了。我不需要那些旧的了。
我仍然认为通过/dev/disk/by-id/引用磁盘是个好主意。它们在重新启动时和磁盘在服务器中物理移动时是稳定的(我对此进行了测试)。我有点失望的是，发布升级会阻止磁盘id命名。但我很高兴能在我的案件中通过再次输入池来解决问题。
我也有同样的理由。谢谢你的提示使用别名！也许我会用这个。
