Intalling Experimentatl ZFS

What are we doing?

Here we are attempting to install zfs on fedora server 42 before it is supported. There is not a rpm currently available, at least while writing this, for fedora 42. The linux 6.14 kernel is also not supported.

Here we will look at building the source from the provided tarball file.

First things first

This is not meant to be a guide but more of a documentation of my journey into building openZFS for fedora 42 using a fresh VM. This isn’t a production environment and isn’t even running on my current server. This is me experimenting and seeing if this is feasable so I can decide if I want to upgrade to fedora 42. If it is too much of a pain then I will probably wait for more support for fedora 42 before upgrading.

This is just me playing with building on an unsupported kernel. Kernel 6.14.2-300.fc42.x86_64

The journey

Here is what happens when we follow the simple install like the one recommended on the openZFS website.

$ dnf install -y https://zfsonlinux.org/fedora/zfs-release-2-6$(rpm --eval "%{dist}").noarch.rpm

Whoops, we’re too early for their official release of the rpm. What do we do here?

Let’s download the tarball file from their website and extract it.

$ wget https://github.com/openzfs/zfs/releases/download/zfs-2.3.1/zfs-2.3.1.tar.gz

Let’s extract that thang using tar --extract -f zfs-2.3.1.tar.gz.

Once we cd into the extracted dir we can see we have a Makefile.am and Makefile.in file. After doing a little digging, since I didn’t recognize this make file config, we figure out that we need automake installed. A quick dnf and we get it on our system.

Here is what that dir looked like.

Running automake gives us this.

$ automake
aclocal.m4:17: warning: this file was generated for autoconf 2.71.
You have another version of autoconf.  It may work, but is not guaranteed to.
If you have problems, you may need to regenerate the build system entirely.
To do so, use the procedure documented by the package, typically 'autoreconf'.
configure.ac:43: error: version mismatch.  This is Automake 1.17,
configure.ac:43: but the definition used by this AM_INIT_AUTOMAKE
configure.ac:43: comes from Automake 1.16.5.  You should run
configure.ac:43: autoreconf -f (or otherwise erase all old files, run
configure.ac:43: aclocal to recreate aclocal.m4, and rerun automake).

So we run what it tells us and get this.

$ autoreconf -f
configure.ac: warning: AM_GNU_GETTEXT is used, but not AM_GNU_GETTEXT_VERSION or AM_GNU_GETTEXT_REQUIRE_VERSION

automake Then runs with no output or errors.

Checking with ls again gives us this.

configure: WARNING:

        You are building OpenZFS against Linux version 6.14.2-300.fc42.x86_64.

        This combination is considered EXPERIMENTAL by the OpenZFS project.
        Even if it appears to build and run correctly, there may be bugs that
        can cause SERIOUS DATA LOSS.

        YOU HAVE BEEN WARNED!

        If you choose to continue, we'd appreciate if you could report your
        results on the OpenZFS issue tracker at:

            https://github.com/openzfs/zfs/issues/new

        Your feedback will help us prepare a new OpenZFS release that supports
        this version of Linux.
