将 ubuntu 20.04 升级到 ubuntu 22.04 后，zfs 管理磁盘完全消失了

我在 Supermicro X9DRW-3LN4F+/X9DRW-3TF+ 上安装了 ubuntu 20.04，配有 2 个 NMVe 驱动器和 4 个 SATA 驱动器。我在 4 个 SATA 驱动器上设置了 zfs 池，如下所示：

$ sudo zpool status
[sudo] password for igdvs: 
  pool: data
 state: ONLINE
  scan: none requested
config:

    NAME                                         STATE     READ WRITE CKSUM
    data                                         ONLINE       0     0     0
      scsi-SATA_Hitachi_HUA72303_MK0371YHK2E0XA  ONLINE       0     0     0
      scsi-SATA_Hitachi_HUA72303_MK0371YHK2L7NA  ONLINE       0     0     0

      scsi-SATA_Hitachi_HUA72303_MK0331YHGZHD7A  ONLINE       0     0     0

errors: No known data errors

因为我的 lxc 容器在 zfs 池上运行，并且我想升级 ubuntu 20.04 主机内核，以便我的一个 lxc 容器可以受益于新的主机内核功能。所以我决定安装 5.15.0-69-generic包，然后重新启动主机，但重新启动后，5.15.0-69-generic无法检测到 zfs 管理的驱动器。

然后我决定将主机升级到 Ubuntu 22.04，但升级后，主机仍然无法检测到 zfs 管理驱动器，SATA 驱动器完全消失了，没有显示在fdisk -l、lsblk、 中/dev/disk/by-id。

$ ls -l /dev/disk/by-id/

从 BIOS 中，我可以看到 4 个 SATA 驱动器。

问题是升级后，我有内核 grub 启动顺序：

$ sudo grub-mkconfig | grep -iE "menuentry 'Ubuntu, with Linux" | awk '{print i++ " : "$1, $2, $3, $4, $5, $6, $7}'
Sourcing file `/etc/default/grub'
Sourcing file `/etc/default/grub.d/init-select.cfg'

4 : menuentry 'Ubuntu, with Linux 5.4.0-147-generic' --class ubuntu
5 : menuentry 'Ubuntu, with Linux 5.4.0-147-generic (recovery mode)'

并且/etc/default/grub有：

$ cat /etc/default/grub
# If you change this file, run 'update-grub' afterwards to update
# /boot/grub/grub.cfg.
# For full documentation of the options in this file, see:
#   info -f grub -n 'Simple configuration'

#GRUB_DEFAULT=0
GRUB_DEFAULT="1>2"
GRUB_TIMEOUT_STYLE=hidden
GRUB_TIMEOUT=0
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT=""
GRUB_CMDLINE_LINUX=""

因此5.15.0-69-generic成为默认启动内核，注意这不是 Ubuntu 操作系统升级的错误，而是我/etc/default/grub在不知情的情况下更改了默认启动内核。因此，教训是，当您拥有 zfs 管理磁盘时，不要单独安装新的内核包，并在升级操作系统后检查您的默认启动内核，以及您是否之前更改了默认启动内核。这种情况不常见，应该很少发生，但人们确实会犯错误
