failing_nixos_ZFS.md

Based on https://nixos.org/wiki/ZFS_on_NixOS I did the following

Added

  boot.supportedFilesystems = [ "zfs" ];

to configuration.nix

Then run

nixos-rebuild switch
modprobe zfs
  
zpool create -f -o ashift=12 -m /mnt/zdata zdata \
               mirror \
                  ata-TOSHIBA_HDWD130_Y6CJLGNAS \
                  ata-TOSHIBA_HDWD130_Y6CJGJMAS
                
zfs create -o mountpoint=legacy zdata/home 
zfs create -o mountpoint=legacy zdata/roothome
mount -t zfs zdata/home /home   
mount -t zfs zdata/roothome /root

nixos-generate-config
nixos-rebuild switch

All of the above seems to work correctly, however on reboot my zpool disappears and I have to run zpool import zdata to get the pool back.
