Kernel with zfs module

[y8]

Hi.

Since Ubuntu 16.04 comes with native zfs support, it will be nice to see kernel with zfs module enabled.

Hi @y8

You can install zfs on x86_64 4.5.7 std #2 latest, can you switch your bootscript and follow the commands below.

EDITED

$ apt-get update
$ apt-get install -y libssl-dev
$ apt-get install -y zfsutils-linux # will fail on dkms
$ zcat /proc/config.gz > /boot/config-4.5.7
$ cd /tmp;  wget https://www.kernel.org/pub/linux/kernel/v4.x/linux-4.5.7.tar.xz && tar xf linux-4.5.7.tar.xz
$ cp -r /tmp/linux-4.5.7 /lib/modules/4.5.7-std-2/build && cd /lib/modules/4.5.7-std-2/build/
$ cp /boot/config-4.5.7 .config
$ make oldconfig
$ make prepare scripts
$ apt-get remove -y zfsutils-linux
$ apt-get install -y zfsutils-linux
$ cd /lib/modules/4.5.7-std-2/build && make -j4
$ dkms --verbose install spl/0.6.5.6
$ dkms --verbose install zfs/0.6.5.6
$ dkms status
spl, 0.6.5.6, 4.5.7-std-2, x86_64: installed
zfs, 0.6.5.6, 4.5.7-std-2, x86_64: installed
$ modprobe zfs
$ zpool list
no pools available

Hi @QuentinPerez,

Just tired.

root@zfs-test:~# zpool list
The ZFS modules are not loaded.
Try running '/sbin/modprobe zfs' as root to load them.

spl, 0.6.5.6: added

Just in case I've tried to reboot the server, but nothing changed.

@y8 . Maybe this works https://gist.github.com/moul/18e8ec495728e9db3c1e253719bd0d49 from this thread https://github.com/scaleway/kernel-tools/issues/257

Hi @QuentinPerez,

Yes, with updated instructions I managed to get working zfs+docker installation. Pools survived the reboot, and DSSD can be used as L2ARC cache, as zfs didn't complained about empty block device after archive/start sequence.

But installation takes about 1.5 hours on C2L, so anyway it will be much better to see this in stock bootscript.

Hi @QuentinPerez, any update on when zfs will be available out of the box ?

[QuentinPerez]

Hi @tlvenn, Unfortunately, I think that zfs module will be not available out of the box, because it depends of severals dependencies

Hello I got a VPS in scale way only to run ubuntu 16 with LXD and Oh surprise, it doesn't work ? What's going on ?

modprobe zfs

modprobe: FATAL: Module zfs not found in directory /lib/modules/4.5.7-std-3

It is native to ubuntu 16 with zfs.ko already compiled. why is it complicated to keep it as kernel module ?

Thanks

[niwinz]

seems like the linux kernel 4.5.7 headers are not included, but they are needed in order to compile the new modules

[meyskens]

@niwinz the readme of this repo explains how to get them

[FLYBYME]

Anyone have a docker image that has the right kernel? I'm looking to create a scale way image.

I have successfully installed ZFS C2M with 4.4.94-mainline-rev1 kernel First: apt-get install build-essential libssl-dev

Then, run the script from the article https://github.com/scaleway/kernel-tools#how-to-build-a-custom-kernel-module

Afrter that:

export KDIR=/lib/modules/$(uname -r)/build/
apt-get install zfsutils-linux -y
