zfs module not loaded on fedora 23

[thibaut noah]

Hello, does anyone run zfs on fedora 23?
I could use some insights on how to install it properly (the documentation
just gives 2 commands so...)
Some people ran into the same issues apparently but i couldn't find one on
fedora.
If anybody has his hands on real documentation or whathever i'll take it
thanks.
Meanwhile i'll keep crawling google

Thanks for mentioning this.  It sounds like the best thing since sliced
bread.  The fly in the ointment is the CDDL licensing incompatibility
with the gpl, so it can't go directly in the linux kernel.

Here's an article from IBM on how to use it with zfs-fuse.
http://www.ibm.com/developerworks/library/l-zfs/

This article from wikipedia says that it is gentoo and ubuntu that have
the best support and documentation for zfs.
https://en.wikipedia.org/wiki/ZFS
https://wiki.ubuntu.com/ZFS
http://wiki.gentoo.org/wiki/ZFS

The official zfsonlinux development site,  http://zfsonlinux.org/ ,
says that DKMS packages are available for Fedora at 
http://zfsonlinux.org/fedora.html
It still is talking about yum, but the commands probably would work
with dnf.

But, I don't think anaconda will install to a zfs file system, so it
would be necessary to create the zfs partitions from an installed
version of Fedora, and copy or rsync with the appropriate command an
already installed Fedora to get Fedora installed on a zfs file system.

That license incompatibility.

what zfs file system?

I was installing zfsonlinux (the famous documentation with 2lines of
command) using the latest packages available on github (release december
2015) and the module won't load.
The probable code was an error during installation saying the module driver
did not build, it seems when one update fedora some files are missing
(since the system decide on it's own to switch to a newer kernel) so the
install failed?

Basically i'm looking for a fedora user who ran into the same issue.

Why not just get it prebuilt for Fedora? zfsonlinux.org has a package
specifically for Fedora.

That's exactly what i did and it ain't working

I suggest filling an issue ticket with upstream, or ask on their list or
forum.

Hey all,

I ran in the same problem. I removed the ZFS repo of ZFS itself. I
installed the Fedora version, after that the ZFS pool was unable to be
mounted (something with dependencies of features).

I then proceeded to remove everything of ZFS on my system and installed
again the ZFS repository. This turned out to be the winning move. Why? I
don't know, but the ZFS packages of the repository compiles something.
So, my bet it does something to the kernel and with the upgrade of
Fedora 23 it got broken.

Installed packages ATM:

@maikel : Not the same issue mate, this is the first time ever i install
zfsonlinux and my packages are for fedora 23.
I used the new packages available through github (specific for fedora 23),
the module could not build for whathever reason, seems that it is looking
for files i do not have since a genius decided that when you update the
system why not update the kernel itself #yolo.
So i'm screwed, i have absolutly zero knowledge in kernel so i have no idea
how to get those files back (something like kernel-header, sources etc) and
i have to boot on my previous kernel otherwise i cannot launch my qemu vm
which uses vfio.

@chris : already did, still waiting for an answer...

You aren't giving us any useful information. There is no such error as
"could not build for whatever reason". Give us the actual failure message
instead of being coy about it.

Best. Star in a new Terminal window, follow their two steps, copy paste the
entire result to fpaste.org, and then post the URL here.

Hopefully you filled a kernel bug on that?

In the meantime you need to use --exclude=kernel whenever you do system
updates or it will update the kernel and kernel-headers.

And there can be only one kernel-headers version installed at a time. This
can get tricky (OK annoying).

What do you get for

dnf downgrade kernel-headers

Does it correctly offer to install the version for the kernel needed for
vfio? If yes, let dnf downgrade kernel-headers. Then retry reinstalling ZFS
stuff.

Next look at man dnf.conf to see how you can add an exclude for the kernel,
until the kernel vfio bug gets fixed.

Sorry about the enigmatic error message, truth is i wasn't home so i
couldn't get it.

Kernel bug? I thought this was normal behaviour so no.
I didn't know that, this can be annoying indeed, is there a technical
reason behind? Or they just don't trust users?

Downgrade kernel-headers and reinstalling kernel-devel and zfs after
removing them was successfull, zfs module was run successfully.
The module coud not build because it detected the new kernel-headers
(4.3.3) and i was log with 4.2.5.
Thanks for the help
