[Bug 2031174] Re: booting into initramfs not importing zfs pool

[Julian Andres Klode]

I can't comment on zfs, but are you sure you have zfs-linux installed
and not zfs-fuse?

** Package changed: grub2 (Ubuntu) => zfs-linux (Ubuntu)

** Changed in: zfs-linux (Ubuntu)
       Status: New => Incomplete

Title:
  booting into initramfs not importing zfs pool

Status in zfs-linux package in Ubuntu:
  Incomplete

Bug description:
  With root on zfs ubuntu boots into initramfs not finding the pool.

  No pool imported. Manually import the root pool
  at the command prompt an then exit
  Hint: Try: zpool import -N

  zpool import -N

  imports the pool:
    pool: rpool
      id: ....
   state: online
  status: Some supported features are not enabled on the pool.
  action: The pool can be imported using its name or nummeric identifier ...

  zpool list
  no pools available
  zpool import rpool
  zpool list
  ....
  rpool 232G 215G 17.4G 48% 92% 1.00x online -

  exiting the initramfs commandline makes the system boot further, then

  find: /dev/zvol/: no such file or directory
  find: /dev/zvol/: no such file or directory
  cannot open "/ROOT/ubuntu_sxcpx": No such file or directory
  ...
  mount: mounting /dev on /root/dev failed: no such file or directory
  mount; mouniing /run on /root/run failed: no such file or directory
  run-init: can't execute /sbin/init: no such file or directory
  [... further run-init messages about missing file or directory]
  No init found. Try passing init= bootarg

  A second ctrl-d leads to a kernel panik because of killing init.

  Seems update-grub generating grub-configurations unusable with root on
  zfs and /boot on ext4
