+# 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.
