  1. Great! Thanks @SvenHz for sharing your experience! Yes, it's very likely the issue I mentioned above with binutils, for the Debian Buster image I am actually sure as the stable repositories still have version 2.31 which is too old. The simple solution here is to use the packages from the Debian testing repository. This can be simply done by adding two files: /etc/apt/sources.list.d/testing.list: deb http://httpredir.debian.org/debian testing main #deb-src http://httpredir.debian.org/debian testing main /etc/apt/preferences.d/10_
  2. I just recently upgraded my Helios4 to Armbian 20.11.6 with kernel 5.9.14-mvebu. I encountered some minor hiccups, which turn out to be either a kernel or binutils bug, but the binutils developers fixed this in the 2.35 release which you can install from testing (see https://github.com/openzfs/zfs/issues/11444 for the details). I haven't tested this on a 5.10-kernel, nor have I made the switch to ZFS 2.0 yet. But according to @Igor this seems to work also just fine. @SvenHz, if you get this working on your Helios4, I would appreciate if you could report this here, just to keep trac
  3. Thanks @Steven Keuchel for clarifying this. I am currently running zfs 0.7.12 with the default memory settings on my helios4 and haven't encountered any issues yet. Regarding zfs 0.8, it would be good if you could post your experience with the patched version from zfsonlinux/zfs#9967 in that PR to get more feedback on the changes. We also still need zfs test results from other ARM 32-bit systems to establish a baseline before this can get merged.
  4. @SvenHz I made some progress on tracking down this issue with zfs 0.8 on the Helios4, more precisely James Robertson (@jsrlabs) identified and fixed the missing Thumb-2 instructions used by the Armbian kernel, see the discussion on the ZFS mailinglist. I went ahead and opened a bug report (zfsonlinux/zfs#9957), and one of the zfs developers proposed a fix in this pull request: zfsonlinux/zfs#9967. However, the fix needs testing, so I thought to bring this up here in the hope that someone else will give this a shot as well.
  5. I finally got ZFS installed on my Helios4 using Armbian 19.11.3 Buster with Linux 4.19.84, but I had to stick with ZFS version 0.7.12, as advise by @SvenHz in this post. Loading the ZFS 0.8 module would fail with the same error. @Steven Keuchel Thanks again for your input on the kernel/ZFS memory settings. I had a more detailed look at your settings and noticed that you set `zfs_arc_max=805306368` (i.e. to 768 MB), which corresponds to the maximum `vmalloc` you seem to use. Or were those ZFS settings with `CONFIG_VMSPLIT_2G` and you use in fact an even higher value for `vmalloc`?
  6. @gprovost Sure. I wasn't aware that you accept community contributions to the wiki. I might take a stab at that once I have my own setup working ... If someone else, probably more experienced with ZFS, is up for that, please go ahead - I for one would certainly appreciate it.
  7. @Steven Keuchel sorry for my late reply and thanks a lot for your advice regarding the kernel memory configuration. Much appreciated! I will probably start with a readily available kernel and set the correct parameters as suggested, and will later on look into compiling my own kernel. Do you have any advice regarding the compilation, any pointer to documentation or even a config file would be greatly appreciated here. @SvenHz Thanks for sharing your experience with zfs 0.8.2! I will stick to the 0.7 series if at all possible then for now as well. I think it would be good to

  9. @qstaq this sounds interesting. Would you be willing to share these scripts/settings either in public or private? I reckon this could be very useful, especially for beginners like me.
