kernel panic on creating symlinks

[Ritesh]

Hi all,

I've been using maczfs as my main data store on two different machines for quite some time now. However, ever since updating to Mavericks, I've started seeing kernel panics when trying to create symlinks on a ZFS dataset (symlinks get created fine on other HFS volumes). I'm using MacZFS-74.3.2b.pkg on both machines. Unfortunately, I don't have any debug info to report. When the KP happens, the only thing I see on the screen is something like 'BSD process: ln'. There are no .panic files under /Library/Logs/DiagnosticReports/ either. 

If someone can tell me how, I can build from source with debugging information turned on. As you can imagine, not being able to create symlinks is a serious impediment.

Thanks,

Ritesh

Hi Ritesh,

this sounds similar to
http://code.google.com/p/maczfs/issues/detail?id=120

Can you add your details there?

Please include the output of:
- "grep -e zfs /var/log/kernel.log",
- "sudo pkgutil --pkgs | grep -e zfs"
- and of "strings /usr/sbin/zfs | grep -e VERSION"

Regarding panic files, these should automatically be generated. You
can try to set some debug flags to help getting debug output:

run "nvram boot-args"

to get the current settings, then

"sudo nvram boot-args="original_contents debug=0x160"

(The debug parameter is a bit mask, you can add additional flags if you
have your own custom set of flags which you want to also be active.)




We have currently two reports of this, one with a panic report showing
a crash outside our code. So currently it is unclear why this happens.


Best regards

Björn
