![]() ![]() ![]() Once validated, a recap of the different partitions that we are going to create is waiting upon your approval. If you have multiple disks available, an additional screen will present the available choices. ![]() You will find there the Experimental ZFS support option. The options related to this (LVM, LVM+encryption and ZFS) are all under the “Advanced features” screen. We support, for now, only full disk setup. Installing ZFS on root has never been simpler, especially if you compare to the excellent, but very long and manual How-To Ubuntu Root on ZFS created by the OpenZFS community. The installer experience has been reworked to be clearer and offer more focused options for the user. More streamline desktop with ZFS on root installation Thanks to this, we are committed to deliver the best OpenZFS on linux experience to our audience by continuing to fix any important issues that arise and backporting any critical fixes from newer releases. ZSys and other components (for instance ZFS bindings) have been updated to work with the new libzfs version. We also backported in Ubuntu 20.04 LTS other fixes in our kernel from the incoming 0.8.4 (and OpenZFS 2.0) release, like encryption performance enhancements. As usual, those releases ( 0.8.2 and 0.8.3) bring a lot of improvements and fixes (note though that we backported some fixes in Ubuntu 19.10 from 0.8.2 into our package to fix some critical issues for our users). We updated from 19.10 to 20.04 LTS OpenZFS to its latest and greatest available release (0.8.3). We hope to be able to drop this experimental support in the coming cycle, and backport this to a 20.04.x release. With OpenZFS on Ubuntu 20.04 LTS, we are building the first steps of getting the Ubuntu bullet proof desktop. The installer highlights this in the corresponding screen. Without further ado, let’s dive into this! ZFS & Ubuntu 20.04 LTSįirst thing to note is that our ZFS support with ZSys is still experimental. We will give you tips on how to tweak it at your convenience if you are a ZFS sysadmin expert, while still keeping ZSys advanced capabilities compatible. Finally, for the more tech savy, we will deep dive in to how we use ZFS, store properties and understanding how the puzzle fits together. We then look at what ZSys, our dedicated helper for ZFS systems, can do for you and how you can interact with it. Here we cover what’s new compared to 19.10 in term of installation and general features. I strongly suggest you read the 2 above blog posts as introductions to this blog series we are starting. As explained by then, having a ZFS on root option on our desktop was only a first step in what we want to achieve by adopting this combined file system and logical volume manager. In 19.10, we introduced experimental support on the desktop. Ubuntu has supported ZFS as an option for some time. ZFS focus on Ubuntu 20.04 LTS: what’s new? ![]()
