現象
起動すると、サービス開始時点で以下のメッセージを吐き、zfsを開始できなくなった。
[FAILED] Failed to start Import ZAL pools by device scanning.
See 'systemctl status zfs-import-scan.service'
Starting Mont ZFS filesystems....起動後、コマンドを実行するとzfsがロードされていない旨のエラーが出るので、dmesgを確認すると...

issuesなどを参照すると、zfsとsqlのバージョンがあっていない場合に発生するという記述があった。
現象(インストール時)
インストール時に以下のような現象が発生する。
$ sudo aptitude install debian-zfs
Setting up zfs-dkms (0.6.5.7-8-jessie) ...
Loading new zfs-0.6.5.7 DKMS files...
First Installation: checking all kernels...
Building only for 3.16.0-4-amd64
Building initial module for 3.16.0-4-amd64
configure: error:
*** Please make sure the kmod spl devel package for your distribution
*** is installed then try again. If that fails you can specify the
*** location of the spl source with the '--with-spl=PATH' option.
Error! Bad return status for module build on kernel: 3.16.0-4-amd64 (x86_64)
Consult /var/lib/dkms/zfs/0.6.5.7/build/make.log for more information.
原因
splがインストール対象のzfsパッケージと一致しないことにより発生していた。
splのバージョンを確認する
$ aptitude versions spl-dkms Package spl-dkms: p 0.6.5.7-5-jessie <NULL> 500 i 0.6.5.8-2 unstable 500
対応方法
いったんすべてをキレイキレイする。
$ sudo aptitude purge debian-zfs spl-modules-* spl spl-dkms zfs-dkms zfsutils
ここで再起動することを推奨する。
splをバージョン指定で取得する。

次に、zfs-dkmsをインストールする。

spl-dkmsパッケージがaptitude upgradeで更新されてしまうのを防ぐ。(zfsモジュールが上がった場合は注意する)
$ sudo aptitude hold spl-dkms zfs-dkms No packages will be installed, upgraded, or removed. 0 packages upgraded, 0 newly installed, 0 to remove and 1 not upgraded. Need to get 0 B of archives. After unpacking 0 B will be used.
