To lose all of the information in your storage pool, two disks would have to die. If you are looking to setup a new NAS, and all your other machines are Debian, maybe you should have a look at Openmediavault: NAS with a web gui, based on Debian and with zfs support. I've been very pleased with it's stability & performance. If a single disk in your pool dies, simply replace that disk and ZFS will automatically rebuild the data based on parity information from the other disks. I load the OS on an SSD with a ZFS mirror holding all data & VMs. In a RAID-Z pool, youвЂ™ll still get the speed of block-level striping but will also have distributed parity. RAID-Z requires a minimum of three hard drives, and is sort of a compromise between RAID 0 and RAID 1. RAID-Z is basically an improved version of RAID 5, because it avoids the вЂњ write holeвЂќ by using copy-on-write. This time, letвЂ™s use our three disks to create a RAID-Z pool. First, weвЂ™ll delete the zpool weвЂ™ve created so we can use these disks in a more redundant setup:Д«am, our zpool is gone.

If just one hard drive fails, we will lose our 3 KB file.ДЄssuming that protecting your data is more important than accessing it quickly, letвЂ™s take a look at other popular setups. This makes writing and reading data fast, but also means we have a single point of failure. Then when we go to read the 3 KB file, each hard drive would present 1 KB to us, combining the speed of the three drives. 1 KB would automatically go to sdb, 1 KB to sdc, and 1 KB to sdd. In case youвЂ™re not familiar with what that means, imagine we created a 3 KB file on /geek1. What weвЂ™ve done so far is create a 9 TB dynamic stripe pool (effectively, RAID 0). Installation takes quite a while, but once itвЂ™s finished, run $ sudo zfs list to make sure itвЂ™s installed correctly. You should still be able to follow along no matter what, as the ZFS commands wonвЂ™t change across different distributions.

If you have some other distribution, check out and click on your distribution under the вЂњPackagesвЂќ list for instructions on how to install ZFS.ДЄs we continue with this guide, weвЂ™re going to use Ubuntu because that seems to be the #1 choice for Linux geeks. $ sudo add-apt-repository ppa:zfs-native/stable Solaris and FreeBSD should already come with ZFS installed and ready to use. Here are the commands for installing ZFS on some of the most popular Linux distributions. This section assumes that youвЂ™re using ext4 or some other file system and would like to use ZFS for some secondary hard drives. Since weвЂ™re only covering the basics in this guide, weвЂ™re not going to install ZFS as a root file system. This allows you to save money, make setup easier, and have access to superior RAID levels that ZFS has improved upon. ZFS is capable of many different RAID levels, all while delivering performance thatвЂ™s comparable to that of hardware RAID controllers. OpenZFS has been ported from FreeBSD to Linux in support of the ZoL (ZFS on Linux) installation on Linux distros like Debian, Arch, Fedora, Gentoo, OpenSuse, RHEL and CentOS, and Ubuntu. No need to spend time partitioning, formatting, initializing, or doing anything else to your disks вЂ“ when you need a bigger storage вЂњpool,вЂќ just add disks.

Similarly with ZFS, when you need more hard drive space, you put in another hard drive and youвЂ™re done. When you need more memory in your computer, you put in another stick and youвЂ™re done. The creators of ZFS want you to think of it as being similar to the way your computer uses RAM. Also, while ZFS is busy quietly checking your data for integrity, it will do automatic repairs anytime it can. You can rest assured that your files and their redundant copies will not encounter silent data corruption. Storage 100G 129K 100G - 0% 0% 1.Everything you do inside of ZFS uses a checksum to ensure file integrity.
