To further increase redundancy you can add more drives.īefore you start copying files to the pool, you still have some more work to do. Now the two hard drives will be mirroring the files. This time you will get some output that means your pool is created. In my case the mount point was ‘/mnt/bank, pool was ‘swapool’ Let’s now create the zpool in this format: /sddįrom this output note down the IDs that start with ‘wwn’, so in my case it was ‘wwn-0x50014ee20922e8a8’ and ‘wwn-0x50014ee20b453ec7’ In my case the two drives that I will be using for pool are sdc and sudo ls -l /dev/disk/by-id/ Here is an example from my system (I have removed output for sda, that’s the drive where Ubuntu is installed. This command will give you a long output. Then run the following command to check if any ‘pools’ or hard drives exist on the system: Sudo apt-get install ubuntu-zfs sudo /sbin/modprobe zfs Now install the package and load the module: Sudo apt-add-repository ppa:zfs-native/stable While ZFS comes pre-installed in the upcoming Ubuntu 16.04 release, we need a PPA to install it on 14.04 Once you have your hard drives, you can install ZFS. (In my case, I take 2 external backups and keep one at my inlaws place.) I strongly recommend having a third external hard drive so that you can take regular backups of your data.If you have hard drives of different capacity, your total storage will be the size of the smaller hard drive. To create RAID-Z, you need a minimum of two hard drives with same storage capacity.I strongly recommend using the LTS (long term support) release of Ubuntu on any file server.At least 8GB of RAM (1GB for Ubuntu and then 1GB of RAM per TB of data).One for Ubuntu, which must be installed on a separate SSD or hard drive) and two for the storage pool. Here’s how to get started with ZFS on Ubuntu. Initially I considered FreeNAS and ran it for a while, but I am more comfortable with Linux and I prefer complete control over my server. But there are some licensing issues around ZFS, which I’ve written about previously. ZFS, on the other hand, is time-tested, stable and extremely feature rich: It includes pooled storage (zpool), copy-on-write, snapshots, data integrity verification, automatic repair, protection against corruption, etc. Btrfs is very new and is still under heavy development so I don’t recommend using it yet. There are two excellent file systems that can do this job: ZFS and Btrfs. So you you have to add redundancy to it, you have to ensure multiple physical backups. Because nothing is ever stored on such devices in my house.īut it’s not a good idea to keep all your eggs in one basket. If my main PC or laptops breaks, I don’t have to worry about rescuing data that’s stored on that machine.I can work across multiple devices – laptop, PC, tablet, phone – without worrying about copying files between them.It’s a centralized file server so anyone in my local network can access these files.Since all of my data is stored in one location, I can easily manage, maintain and secure it.
