RELATED: How to Install and Use ZFS on Ubuntu (and Why You'd Want To) Finding the ZFS Options During Installationĭuring the Ubuntu install the “Installation Type” screen lets you choose to erase the disk you’re installing Ubuntu on or to do something else. With Ubuntu 21.10 due in October 2021, it’s a good time to see how the ZFS offering in Ubuntu is maturing. To get that support you’ll need to install ZFS as you install Ubuntu. The ZFS options are still tucked away, but they’re there and no longer just for the intrepid or foolhardy. Canonical officially supports ZFS but only in full disk setups.
In Ubuntu 20.10 the warnings were removed. Ubuntu has offered ZFS for some years now, but always with warnings and caveats. It combines features that deliver file system pooling, cloning and copying, and its RAID-like functionality, natively. It has built-in functions such as true copy on write that protect your data from corruption. ZFS functions as its own volume manager and RAID controller. There’s much more to ZFS than sheer capacity-as mind-boggling as that is. A zebibyte (2 70 bytes) is larger than a zettabyte (10 21 bytes), but not by an order of magnitude. Nowadays, ZFS supports file storage of up to 256 zebibytes. To give you an idea of what that means, a zettabyte is a billion terabytes. Being able to work with larger numeric values is one of the factors that made ZFS capable of handling zettabytes of storage. The ZFS architecture is based on 128 bits instead of the more common 64 bits of other files system. ZFS originally stood for Zettabyte File System. ZFS is a high-capacity, fault-tolerant file system. The open source version of ZFS-openZFS-is managed and maintained by the OpenZFS project. Inevitably, this was ported to Linux where it gained wider exposure. However, in a typical act of altruism, from 2005 onwards, Sun released an open source version of ZFS. Following Oracle’s acquisition of Sun in 2009, ZFS is now under Oracle Corporation ownership. ZFS is an advanced file system that originated at Sun Microsystems for use with their Solaris operating system.
