Easily the most advanced file system (feature-wise) currently available. However it is pretty much limited to solaris (and linux/BSD if you are fine using an older version without the latest features, and without any kind of official support from either the people who actually write ZFS OR linux/bsd!). The z/OS® Distributed File Service (DFS™) zSeries® File System (zFS) is a z/OS UNIX® System Services (z/OS UNIX) file system that can be used in addition to the hierarchical file system (HFS). ZFS file systems contain files and directories that can be accessed with z/OS UNIX application programming interfaces (APIs).

FreeNAS is the world’s most popular open source storage operating system not only because of its features and ease of use but also what lies beneath the surface: The ZFS file system. With over seven million downloads, FreeNAS has put ZFS onto more systems than any other product or project to date and is used everywhere from homes to enterprises.
But why ZFS?
FreeNAS uses ZFS because it is an enterprise-ready open source file system and volume manager with unprecedented flexibility and an uncompromising commitment to data integrity. ZFS is a truly next-generation file system that eliminates most, if not all of the shortcomings found in legacy file systems and hardware RAID devices. Once you go ZFS, you will never want to go back.
Unprecedented Flexibility
ZFS helps you avoid most storage planning mistakes by pooling together the blocks provided by all of your disks and allowing you to divide the available space into highly-configurable file systems. ZFS includes the permissions and quotas of traditional file systems but also includes transparent compression levels, capacity reservations, and clonable snapshots. Of these features, snapshots will probably be the one that forever changes the way you think about storage. Imagine if you could bring “what if?” style experimentation to your storage.
Uncompromising Data Integrity
Unprecedented flexibility is pointless without dependability. ZFS is uncompromising about data integrity and data redundancy. ZFS creates a chain of trust for your data by checksumming data when it is written and verifying the checksums when it is read. It even checksums the metadata that describes the file system and allows you to periodically verify all checksums to determine if your infrequently-used data or backups are suffering silent data corruption a.k.a. “bit rot”. By taking these precautions, ZFS will never return you corrupt data from disk.
Knowing your data is intact is one thing but combating disk unreliability is quite another. ZFS can maintain data redundancy through a sophisticated system of multiple disk strategies. These strategies include mirroring and the striping of mirrors equvalent to traditional RAID 1 and 10 arrays but also includes “RaidZ” configurations that tolerate the failure of one, two or three member disks of a given set of member disks.

A friend of mine likes to try ZFS on CentOS 7, therefore I decide to make a guide for him. The following instructions have been well tested on CentOS 7.
Before you decide to put ZFS in a production use, you should be aware of the following:
- ZFS is originally designed to work with Solaris and BSD system. Because of the legal and licensing issues, ZFS cannot be shipped with Linux.
- Since ZFS is open source, some developers port the ZFS the Linux, and make it run at the kernel level via dkms. This works great as long as you don’t update the kernel. Otherwise the ZFS will not be loaded with the new kernel.
- In a ZFS/Linux environment, it is a bad idea to update the system automatically.
- For some odd reasons, ZFS/Linux will work with server grade or gaming grade computers. Do not run ZFS/Linux on entry level computers.
Instructions
By default, ZFS is not available in the standard CentOS repository. We will need to include some 3rd party repositories here.
Zfs Windows Server
It is very likely that the system will install a new kernel. You may want to reboot the computer before installing the ZFS.
Please make sure that the system does not update automatically. If you need to update the system, please exclude the kernel and related modules from the update.
Now you are on the latest kernel. Let’s install the ZFS:
Now, you can create a simple stripped ZFS. Stripped ZFS gives you the best performances and zero data protections. When referencing the disks, we don’t want to use /dev/sd*, instead, we want to use the device id directly, e.g., /dev/disk/by-id/wwn-0x8000c8004e8ac11a
Once you identify the list of the hard disks, we can create a simple stripped ZFS. This will create a ZFS under /storage. You can replace storage to anything you like.
storage is like a big umbrella. Under this umbrella, we will need to create multiple “partitions” for storing data.
If you have a fast CPU like i7, you may want to turn on the compression. This will reduce the amount of data write to the system, and it will improve the overall performance.
Finally we want to change the ownership and the permissions

Now, run df and you should be able to see the ZFS in your system.
Windows 7 Zfs Support
You can monitor the health of the ZFS system.
For some very odd reasons, ZFS will not be loaded automatically. We want to make sure that ZFS will be loaded after reboot.
Now you can try to test the ZFS by running dd or copying a big file to the ZFS. If you are not happy with the configurations, you can always destroy it and re-create the ZFS again.
