For those that are curious, the addition of ZFS for Ubuntu 19.10 means even greater things are yet to come.

#UBUNTU VOLUME MANAGER FULL#

The full release will be available on October 17, 2019. Of course there is so much more ZFS can do (such as cloning snapshots and replication), but this gives you an idea of what’s coming for the next release of Ubuntu Linux. Sudo zfs rollback the command time enough to rollback the changes and viola! The Documents folder has returned ( Figure D).

What do you do? Since you took a snapshot, you can roll it back with the command:

Imagine that folder contained all of your work, school, or research documents? If you didn’t have a backup (which you should), you might find yourself throwing a fit or 12. The Documents folder is now gone ( Figure C). We’ll delete the Documents folder in my home directory with the command: Sudo zfs snapshot snapshots generally complete very quickly, regardless of how much data is stored in the location. To create a snapshot named WED101619, the command would be: It is important that you know the name of the dataset, as you cannot simply take a snapshot using the directory name or path. The dataset I’ll be using is named rpool/USERDATA/jack_bwcn4u. You should see a complete list of your datasets ( Figure B). To find the name of the home dataset, issue the command: I’m going to make a snapshot of my home directory. The first thing you must do is find the name of the ZFS dataset you want to use.

I’m going to show you how to create a snapshot, make a change, and the roll back that snapshot. In fact, everything just works, as you’ve come to expect with Ubuntu Linux. At first blush, you won’t notice anything different with the ZFS system. When the installation completes, reboot and log in.

#UBUNTU VOLUME MANAGER INSTALL#

Select that option and then click Install Now. When installing Ubuntu 19.10, you are given the option of using the ZFS file system ( Figure A). Note: I’ve been working with the final release candidate, so the ZFS support is still in the experimental phase. What do you do? If you have ZFS and you’ve created a snapshot, you can roll that system back to the snapshot where everything was working fine.Īlthough the concept isn’t new to the world of computing, it’s certainly not something Ubuntu has had by default.

#UBUNTU VOLUME MANAGER SOFTWARE#

You’ve lost data or an installation of a piece of software has messed up the system. But out of those supported features, it’s the snapshots and rollbacks that should have every Ubuntu user/admin overcome with a case of the feels. So yeah, ZFS is a big deal, which includes some really great features.

ZFS is a combined file system and logical volume manager that is scalable, supplying support for high storage capacity and a more efficient data compression, and includes snapshots and rollbacks, copy-on-write clones, continuous integrity checking, automatic repair, and much more.

No matter what other new features find their way into the release, they are all overshadowed by one addition that is long overdue. Outside of that, the various releases over the past few years have been somewhat underwhelming.īut that all ends with 19.10 (Eoan Ermine). Oh sure, a while back you shifted away from Unity and defaulted to GNOME, and that was a bold move–one I believe the majority of users are thankful for. It’s been quite some time since you’ve brought us something truly exciting with a new release.
