+mdadm --zero-superblock --force /dev/sda
+sgdisk --zap-all /dev/sdX
+```
+### Partition disks
+```shell
+sgdisk -n1:0:0 -t1:BF01 /dev/sdX
+```
+### Create zpool
+```shell
+zpool create -o ashift=12 -O atime=off -O compression=lz4 \
+zv1 raidz2 \
+/dev/disk/by-id/ata-WDC_WD60EFRX-68L0BN1_WD-WX21D36PP32E-part1 \
+/dev/disk/by-id/ata-WDC_WD60EFRX-68L0BN1_WD-WX21D36PPLPH-part1 \

+### Create datasets
+```shell
+zfs create zv1/homes
+zfs create zv1/daten
+zfs create zv1/fotos
+```
+### Set dataset quota
+```shell
+zfs set quota=1T zv1/daten zv1/fotos zv1/homes
+```
+### Transfer data
+```shell
+rsync --stats -avhP --exclude Pictures root@atlas:/mnt/save/fet_daten/ /zv1/daten/
+rsync --stats -avhP root@atlas:/mnt/save/fet_daten/Pictures/ /zv1/fotos/
+rsync --stats -avhP root@atlas:/home/ /zv1/homes/

+```shell
+zpool add zv1 log mirror /dev/nvme0n1p2 /dev/nvme1n1p2
+```
+### If intend using ACL (not done!)
+```shell
+zfs set xattr=sa <dataset>
+zfs set acltype=posixacl <dataset>
+```
+## ZFS Maintenance
+```shell
+zpool status -v
+zpool list -v
+zpool get all
+zpool history
+zpool scrub zv1
+```
+## MDADM Maintenance
