Create and Use ZFS Pool
Install ZFS
apt install zfsutils-linux
The initiall install may give some errors, but that is okay. Simply reboot to fix it.
Create Pool
if you want to create a raid-10 setup with four disks, we can run:
zpool create ${poolname:?} mirror ${mirror1dev1:?} ${mirror1dev2:?} mirror ${mirror2dev1:?} ${mirror2dev2:?}
Make sure to pass device names as given by /dev/disk/by-id. If you give sda, sdb, etc, the pool will break if the system ever changes which physical disk the name sda refers to. The names in /dev/disk/by-id/, however, are guaranteed to always refer to the same physical device.
Create Datasets
zfs create ${poolname:?}/${datasetname:?}
Setup Auto Snapshots
apt install zfsnap
put your commands in crontab.
