Installing And Using ZFS In Linux Mint / Ubuntu – Part 5

Continuing from part 4, in today’s post we’ll learn how to create ZFS data set for a user and mount it to a directory for use:

1. Issue the following commands at the terminal to view zpool status and the available capacity –

sudo zpool status

sudo zfs list

2. Now, we’ll create a ZFS data set called ‘myData’ in ZFS pool ‘myPool’ and enable compression, deduplication and 1 GB quota for the data set. Issue the following commands at the terminal –

sudo zfs create myPool/myData

sudo zfs set compression=on myPool/myData

sudo zfs set dedup=on myPool/myData

sudo zfs set quota=1g myPool/myData

3. Now, we’ll create a desired mount point for myData on Desktop of user ‘ihaveapc’, modify it’s premissions and modify the ZFS data set ‘myData’ to be mounted to this directory. Issue the folowing command at the terminal –

sudo mkdir /home/ihaveapc/Desktop/myPrecious

sudo chmod -R 777 /home/ihaveapc/Desktop/myPrecious

sudo zfs set mountpoint=/home/ihaveapc/Desktop/myPrecious myPool/myData

4. Now we’ll verify that the properties of the ZFS data set ‘myData’. Issue the following commands at the terminal to verify the quota, mount point, compression and deduplication –

sudo zfs list

sudo zfs get all myPool/myData | grep compression

sudo zfs get all myPool/myData | grep dedup

The user can now store his data in directory ‘myPrecious’ and it will get stored in the ZFS data set ‘myPool’ with compression and deduplication. In part 6, we’ll learn how to backup and restore this data via ZFS snapshots and ZFS clones.
