Create ZFS Pool

https://pve.proxmox.com/wiki/ZFS_on_Linux

Introduction

ZFS pool can be built with WWN or partuuid, to be able to run the pool even from an USB case if needed. For normal service, disk ID is sufficient.

Poolname should be customerid, to make deployment easier. Poolname can be changed

Create a ZFS pool with 2 HDD as mirror

Get WWN from HDD

ls -l /dev/disk/by-id/
#richtige HDD suchen, zB ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD -> ../../sdj
#daher ist unsere gesuchte HDD sdj
#WWN suchen, welche auf sdj verweist, hier:
#wwn-0x50014ee20c6324e6 -> ../../sdj
#zweite HDD suchen, zB ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E6FN513C -> ../../sdk
#daher ist unsere gesuchte HDD sdk
#WWN suchen, welche auf sdk verweist, hier:
#wwn-0x50014ee20c629629 -> ../../sdk

Create ZFS Pool with WWN from above

zpool create -o ashift=12 -O compression=zstd poolname mirror /dev/disk/by-id/wwn-0x50014ee20c6324e6 /dev/disk/by-id/wwn-0x50014ee20c629629

Create ZFS Pool in Raidz1

Get WWN from HDD same as above for each HDD

Create ZFS Pool with WWN from above

zpool create -o ashift=12 -O compression=zstd poolname raidz1 /dev/disk/by-id/wwn-<1> /dev/disk/by-id/wwn-<2> /dev/disk/by-id/wwn-<3>

Create a ZFS pool on a single disk with no data redundancy

Find WWN of the HDD

ls -l /dev/disk/by-id/
#find the right HDD, for this example: ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD -> ../../sdj
#the letter of our example HDD is currently sdj
#find WWN of sdj
#wwn-0x50014ee20c6324e6 -> ../../sdj

Create ZFS Pool with WWN from above

zpool create -o ashift=12 -O compression=zstd poolname /dev/disk/by-id/wwn-0x50014ee20c6324e6

Create a ZFS pool on a single disk with 5 partitions for data redundancy

Attention: Very slow performance

apt install parted
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mklabel gpt
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mkpart zfs 0% 20%
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mkpart zfs 20% 40%
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mkpart zfs 40% 60%
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mkpart zfs 60% 80%
parted /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD mkpart zfs 80% 100%

Find the letter of the disk

ls -l /dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD

Result

/dev/disk/by-id/ata-WDC_WD40EFRX-68WT0N0_WD-WCC4E4DF9NJD -> ../../sdh

Find all Partuuid of sdh

ls -l /dev/disk/by-partuuid/ | grep sdh

Result (just one displayed as example)

2c49c49f-4221-324e-afca-23bedbb06677 -> ../../sdh1   #2c49c49f-4221-324e-afca-23bedbb06677 is the partuuid1

Create ZFS pool (adjust ashift if needed)

zpool create -o ashift=12 -O compression=zstd poolname raidz1 /dev/disk/by-partuuid/<partuuid1> /dev/disk/by-partuuid/<par
