Description Moritz Schlarb 2013-01-06 19:18:43 UTC
While emerging the zfs utils in a virtual machine on x86, I ran into the same issues as described here: https://github.com/zfsonlinux/zfs/issues/814

Adding --enable-atomic-spinlocks to configure in sys-kernel/spl did the trick, so it could maybe be worth considering to add that on x86 by default.

Reproducible: Always

Comment 2 Richard Yao (RETIRED) gentoo-dev 2013-01-07 20:27:33 UTC
This issue only occurs on a fraction of x86 systems. I currently do not understand the cause and I would like to change that. Would you attach your kernel .config and the build.log from sys-fs/zfs-kmod?

By the way, I should warn you that x86 is currently not keyworded because x86 support has regressions in comparison to amd64. The main regression is that ZFS likely requires manual tuning of vmalloc and possibly also zfs_arc_max. My plan is to keyword x86 only after upstream does page cache unification, which should eliminate the tuning issue and open the door for more rigorous regression testing by upstream. Until then, it will remain unkeyworded. It should be safe (data integrity-wise) for you to use ZFS on x86, but you will likely encounter glitches such as this until the 32-bit issues have been fully resolved.

build.log

I don't plan to use it productively on x86, I just did a presentation and wanted to show zfs in a virtual machine which only had x86 architecture.

Comment 6 Jordi Marqués 2013-01-11 10:43:05 UTC
#5 attachment is a kernel config where zfs compiles correctly.
Comment 7 Richard Yao (RETIRED) gentoo-dev 2013-01-11 17:23:03 UTC
Moritz, would you attach the config.log from your system?

You can get it by running:

ebuild /usr/portage/sys-fs/zfs-kmod/zfs-kmod-0.6.0_rc13.ebuild clean configure

Then the file would be /var/tmp/portage/sys-fs/zfs-kmod-0.6.0_rc13/work/zfs-zfs-0.6.0-rc13/config.log.

Comment 9 Richard Yao (RETIRED) gentoo-dev 2013-02-05 20:20:31 UTC
The following upstream patch will fix this:

https://github.com/zfsonlinux/spl/commit/dd3678fc29d75286b57e705454bbd7e60e1b44e0

The reason why some people were affected and others were not is that the affectd people were on Linux 3.4 and later. I will backport this patch to sys-kernel/spl later this week.
Comment 10 Richard Yao (RETIRED) gentoo-dev 2013-02-06 01:51:26 UTC
This should be fixed in sys-fs/zfs-kmod-0.6.0_rc14-r1.
