Has OpenSuSE 13.1 dropped support for zfs-fuse ?


Has OpenSuSE 13.1 dropped support for zfs-fuse?

If it has not, what must I add to /etc/zypp/repos.d
to install it?

If it has, I would never have installed 13.1 if I had
known. How do I obtain an unsupported implementation
of zfs-fuse?

Thank you in advance for any and all replies.

13.1 has not been released yet; it is close, but has not been released, so it is difficult to say.

In general, some of the stuff in 'personal' (rather than formal, oS supported, repos - these tend to be described as 'unstable' packages, although that probably isn't the best descriptive term) repos tends not to be available until a week or two after the release, so that makes it even more difficult to give the definitive list of what will be available, eventually.

Both 12.3 and 13.1 have something ZFS in the repos 'filesystems' and 'home:munix9:zfs'; additionally 12.3 has 'spin:invis', which, judging by the git repo on which it is based might be a bit older. 'spin:invis' may well turn up for 13.1 at some time, as might something else.

That said, I don't know what is in these repos; it could be ZFS-on-fuse, native-ZFS or some subset or superset of either or both, but it certainly seems to be something zfs related (and possibly other filesystems?).

Indeed, I did another search-engine inquiry a couple of days later,
and this time it showed up (but I did have to add the following to
/etc/zypp/repos.d, which had not been placed there by the installation
procedure):

[filesystems]
name=filesystems
enabled=1
autorefresh=1
baseurl=http://download.opensuse.org/repositories/filesystems/openSUSE_13.1/
type=rpm-md
keeppackages=0

However, it is not zfs-fuse, but kernel-based, which one normally would
think is preferable, but not in this case, because it doesn't work.
Behold:


landru:/etc/zypp/repos.d # zpool list
Failed to load ZFS module stack.
Load the module manually by running 'insmod <location>/zfs.ko' as root.

insmod: error inserting '/lib/modules/3.11.6-4-desktop/extra/zfs/zfs.ko': -1 Unknown symbol in module


Rebooting made no difference.

Any further assistance would be much appreciated. As always,
thank you in advance for any and all replies.

Here is more information, although I am no closer to a solution.

As indicated in the previous posting, when I downloaded zfs,
yast2 installed zfs.ko into /lib/modules/3.11.6-4-desktop/extra/zfs
but it turns out that on my system (which I downloaded and
installed less than a week ago) `uname -r` produces 3.11.6-3-desktop
(I consider this a bug in yast2).

Copying zfs.ko into the appropriate directory did not help:


landru:/lib/modules # mkdir -p 3.11.6-3-desktop/extra/zfs
landru:/lib/modules # cp -i 3.11.6-4-desktop/extra/zfs/zfs.ko 3.11.6-3-desktop/extra/zfs/
landru:/lib/modules # depmod
landru:/lib/modules # modprobe zfs
FATAL: Error inserting zfs (/lib/modules/3.11.6-3-desktop/extra/zfs/zfs.ko): Unknown symbol in module, or unknown parameter (see dmesg)

My fantasy at this point is that there is one simple command (e.g., upgrading
to a new kernel) that will make everything work perfectly. My fear is that
Novell has a fantasy that people are going to buy their product because of
the btrfs support, and that in consequence they want to discourage use of zfs,
because it is vastly superior to btrfs.


As always, thank you in advance for any and all replies.

Did you ever do exactly that? What happened?

Re: 3.11.6-3 vs 3.11.6-4-whatever; you've got the kernel(s) that you've got. If you have 'gone behind yast's back' to install something, then yast won't know and will get it wrong.

I'm not totally sure whether they care, or not. It is certainly true that, at this point, ZFS is better developed and more 'stable' (probably, more in the sense of 'immutable interfaces', rather than 'crashes on you all the time', but that's still a meaning of stable), but that's not enough to classify it as superior, without any further caveats. As far as speed is concerned, BTRFS seems to have it over ZFS, but that isn't the final word for all use cases. I believe that Novell are still committed to making BTRFS and package management work together, so that you easily roll back system updates, if one should prove problematic, and I'm not sure that are committed to doing that with any other FS, irrespective of the fact that it would seem, superficially, to be possible. And probably if ZFS had been available under a 'friendlier' license five years ago, no one would have really got all that bothered about BTRFS. And the ZFS utilities are certainly a well integrated whole, but whether that makes them all that 'Unix-y' is a slightly different matter.

Why are you using fuse? http://software.opensuse.org/package/zfs

I am not using fuse -- that was simply the original title of the thread.
I am using the ZFS kernel module, as I mentioned above. And
http://software.opensuse.org/package/zfs is precisely where I got
it from.

There was also an earlier question (which I am certain I answered,
but the answer, myteriously, does not appear on the thread -- perhaps
the website had already logged me out by the time I posted it):

>

Yes, I did do exactly that, and posted the results, but it
apparently, and understandably, was lost in all the verbiage.
Here it is again, taken verbatim from my posting of 11-11-13
11:17 AM:


landru:/etc/zypp/repos.d # insmod /lib/modules/3.11.6-4-desktop/extra/zfs/zfs.ko
insmod: error inserting '/lib/modules/3.11.6-4-desktop/extra/zfs/zfs.ko': -1 Unknown symbol in module


I am no closer to a solution than I was at the start of this thread; my
next attempt will be to download the source rpm and try to build a
functioning kernel module from source. Any helpful advice from those
who have successfully done this, or something similar to this, will be
much appreciated.

I have downloaded the zfs source module, but have
not yet attempted to compile & install from source.
Instead, I rebooted into 3.11.6-4-desktop (which,
mysteriously, existed in my /boot directory, although,
mysteriously, I was running 3.11.6-3-desktop, not
3.11.6-4.desktop), hoping that that would work, and
preferring a simple solution to a complex and difficult
one.

Rebooting into 3.11.6-4-desktop did not solve the
problem, although it did change the error messages.
Behold:

It seems that the "insmod" command produced 4 lines of dmesg
output (timestamped "249") and that the "modprobe" command
produced 240 lines of dmesg output (timestamped "262"). The
last two lines of dmesg output, timestamped "301", may also
have been produced by "modprobe".

The following may also be of interest:

landru:/ # find /lib/modules -name spl\*
landru:/ #

If I am not mistaken, zfs depends on spl (Sun Porting Layer,
or words to that effect). I may be mistaken. In any event,
installing the zfs rpm did not install spl.ko (if such a file
is even supposed to exist).

Why, then, do I not attempt to build the modules from source?
It is because I have no confidence whatsoever in the documentation.
This betokens a change in my attitude since my most recent
posting to this forum. But, since my most recent posting
to this forum, I looked at /usr/src/linux/README.SUSE and the
experience has utterly drained me of confidence in the
people who put together the SuSE distribution.

Here is one of the confidence-draining passages from that
document:

At runtime, the setting of the" unsupported" kernel command line
parameter and /proc/sys/kernel/unsupported determines whether
unsupported modules can be loaded or not, and whether or not loading an
unsupported module causes a warning in the system log:

0 = only allow supported modules,
1 = warn when loading unsupported modules,
2 = don't warn.

(the transposition of the open-double-quote and the space
are in the original)

It seems plausible, but observe:


landru:/usr/src/linux # cat /proc/sys/kernel/unsupported
cat: /proc/sys/kernel/unsupported: No such file or directory
landru:/usr/src/linux # echo 1 >/proc/sys/kernel/unsupported
bash: /proc/sys/kernel/unsupported: No such file or directory
landru:/usr/src/linux #


Now, am I to rely on the authors of this document when
undertaking something as perilous as rebuilding my kernel?
Would you?

I would never have installed OpenSuSE 13.1 if I had known
that the OpenSuSE people have dropped zfs-fuse, and that,
over a week later, I would still have found no way to install
native zfs either (putting to the lie the "1-Click Install"
promise of http://software.opensuse.org/package/zfs).

As always, thank you in advance for any and all replies.

I have been using both zfs on linux and zfs-fuse with opensuse. The latter is easy to install and use, the former is more tricky but worthwhile in terms of much better perofrmance.

Let me know if you still need help and I can show you what I did.
