Zfs install

This creates a mirror pool consisting of disks sdd and sde. Now, let us deliberately corrupt sdd drive by writing zeroes into it. We can migrate storage pools between different hosts using export and import commands. For this, the disks used in the pool should be available from both the systems.

The command 'zpool import' lists all the pools that are available for importing. Execute this command from the system where you want to import the pool. We will now move on to the zfs utility. Here we will take a look at how to create, destroy datasets, filesystem compression, quotas and snapshots.

From the above output, observe that though there is no mount point given at the time of filesystem creation, mountpoint is created using the same path relationship as that of the pool. We will now understand how compression works in ZFS. Before we start using compression, we need to enable it using 'set compression'. Once this is done, compression and decompression happens on the filesystem on the fly transparently. In our example, I will be enabling compression on the students directory using lz4 compression algorithm.

Notice that the size used in the filesystem is only 1. We can check the compression ratio as well.. Let me explain quotas with a real-life example. Suppose we have a requirement in a university to limit the disk space used by the filesystem for professors and students.

Let us assume that we need to allocate MB for students and 1GB for professors. We can make use of 'quotas' in ZFS to fulfill this requirement. Quotas ensure that the amount of disk space used by a filesystem doesn't exceed the limits set. Reservation helps in actually allocating and guaranteeing that the required amount of disk space is available for the filesystem. In the above example, we have allocated MB for students and 1GB for professors. Initially they had the size of 2.

Snapshots are read-only copy of the ZFS filesystem at a given point in time. Your submission was sent successfully! ZFS is a combined file system and logical volume manager originally designed and implemented by a team at Sun Microsystems led by Jeff Bonwick and Matthew Ahrens. Features of ZFS include protection against data corruption, high storage capacity ZiB , snapshots and copy-on-write clones and continuous integrity checking to name but a few.

If you are dealing with large amounts of data, or providing a backing filesystem for virtualisation, ZFS is a great choice. This guide will go through the process of installing ZFS on Ubuntu The main components of ZFS are maintained as a standard Ubuntu package, so to install simply run:.

There are two types of simple storage pools we can create. Striped pools are not fault tolerant whereas mirrored pools can survive the failure of one drive. Best Oculus Quest 2 Accessories.
