Second zfs zpool have to import manually.

[fud]

I have two pools in my configuration as can been seen in my config. After failing to boot I dropped into a root shell and got info from systemctl for the zfs import service and it said that pool (zstorage in my config) had to be import with a zpool import -f zstorage as it had been created on another machine.

I wasn't expecting to manually have to do that.

Config:

{ disks ? [
  "/dev/disk/by-id/ata-Samsung_SSD_850_EVO_500GB_S21GNXAG805611X"
  "/dev/disk/by-id/ata-Samsung_SSD_860_EVO_500GB_S4BENS0N804509D"

Weirdly enough I saw the zpool export in my logs and than had the same issue... Exporting a pool should be enough: https://github.com/openzfs/zfs/blob/4d1b70175cf9bdf927351b1188215604d455f669/cmd/zpool/zpool_main.c#L3121 And we also do a force import for the zfs root fs.
