SPL/ZFS installieren:

<source lang="bash">
apt-get update
apt-get install debian-zfs

vi /etc/modules

### ZFS //
spl
zfs
### // ZFS

update-initramfs -u -k all
</source>

FIX: zfs-mount.service

<source lang="bash">
cat /lib/systemd/system/zfs-mount.service

which zfs
which zpool
</source>

falls zfs/zpool unter /usr/local liegen, dann nach /sbin kopieren

ZFS:

<source lang="bash">
lsmod | egrep "spl|zfs"

zpool status
</source>

== Debian 8 (Jessie) System mit (systemd-sysv/sysvinit-core) ==

<source lang="bash">
modprobe spl
modprobe zfs

modprobe: ERROR: could not insert 'spl': Exec format error
modprobe: ERROR: could not insert 'zfs': Exec format error
</source>

<source lang="bash">
ls -all /sbin | egrep "fsck.zfs|zdb|zed|zfs|zhack|zinject|zpios|zpool|zstreamdump|ztest"

Laden erzwingen bei "Versionsbezeichungsdifferenz"

<source lang="bash">
modprobe --force-vermagic spl
modprobe --force-vermagic zfs

zpool status
</source>

=== module laden erzwingen ===

* trotz unterschiedlicher Versionsangabe (ignores vermagic and modversion attributes)

damit sind nicht die module optionen (parameter) gemeint z.B. bei "modinfo MODULNAME -F parm"

<source lang="bash">
touch /etc/modprobe.d/spl.conf
touch /etc/modprobe.d/zfs.conf
</source>

<source lang="bash">
vi /etc/modules

### ZFS //
spl # force=1
zfs # force=1
### // ZFS
</source>

=== zpool mirror erstellen ===

<source lang="bash">
zpool create -o ashift=12 zbackup mirror /dev/mapper/vg-zstorage1 /dev/mapper/vg-zstorage2

lxc-ls | xargs -L1 -I {} zfs create zbackup/lxc/{}
</source>
