zfs tutorial

This explains how to setup openzfs on an ubuntu system.  My system has an iqstor 15 drive array on it, and that is what I will be using in this example.

  1. apt-get install python-software-properties
  2. add-apt-repository ppa:zfs-native/stable
  3. apt-get update
  4. apt-get install ubuntu-zfs
  5. zpool create -f -o ashift=12 tank raidz \
    ata-ST4000DM000-1111 ata-ST40000DM000-2222 ata-ST40000DM000-3333

NAS Build:
zpool create -f -o ashift=12 tank raidz2 \

 

SLC SLOG drive
unit MiB
mkpart zfs 1 16385
mkpart zfs 16285 122104
quit
zpool add tank log mirror <part1> <part2> <part3> (SLOG)
zpool add tank cache (L2ARC)

Filesystems are called datasets:
They all share the storage pool equally

zfs get compressionratio tank
zfs create tank/databases

zfs set compression=lz4 tank/databases
zfs create tank/databases -o compression=lz4

Snapshots:
zfs snapshot tank/databases@friday (start a snapshot)

apt-get install zfs-auto-snapshot (create snapshots on time intervals)
zfs set com.zun:auto-snapshot=true tank/databases
zfs set snapdir=visible tank/databases
Why create multiple file systems/datasets?
zpool scrub tank (check for errors)
zpool scrub cancel (kill scrubbing)
zpool iostat -v 1

zpool replace -f tank <disk1> <disk2> (old drive – new drive)
zpool status (will show the status of resilving)
Z 3,5,9,17,33
Z2 4,6,10,18,34
Z3 5,7,11,19,35

 

zpool status
zpool list
zpool iostat -v 1
zfs get compressionratio tank/databases
zdb (lists what zfs internal cache looks like)
zfs get all tank/databases (show all the paramters for a filesystem)
zfs list -t snapshot (show snapshots)

zfs set quota=10G tank/home/jeff
zfs get quota takn/home/jeff
zfs list -r tank/home

zfs create tank/databases -o compression=lz4

–> replace disk with larger disk
zpool set autoexpand=on tank1
** pull a disk
** check logs for the drive that was removed
zpool detach tank old_1tb_drive
** insert new disk
zpoool replace -f old_1tb_drive new_2tb_drive

 

Mount on Boot:

You need to edit the file /etc/default/zfs with your favourite editor, eg: nano, vim or something else, and change the lines

ZFS_MOUNT='no'
ZFS_UNMOUNT='no'

to

ZFS_MOUNT='yes'
ZFS_UNMOUNT='yes'

User Manual

Creating a raid6 via lvm2:

pvcreate /dev/sd[abscdefghijklmno]
vgcreate iqstor01 /dev/sd[abscdefghijklmno]
lvcreate –type raid6 -l 80%VG -i 13 -n lvm_iqstor01 iqstor01

this created a 10tb lvm, not a 13 tb as I expected.
