Cross reference and questions

Post by grahamperrin » Sat Jan 26, 2013 1:35 am

Thanks for providing such detailed information.

The copies=2 aspect is probably incidental.

The Mountain Lion kernel_task kernel panic in your opening post seems comparable to the panics in a very recently updated topic:

kernel_task kernel panic with Mountain Lion under pressure

For me, the most common example of pressure may be when a VirtualBoxVM runs, but not in front.

(VirtualBox.app alone seems to present no problem.)

In your case I see the org.virtualbox.kext.… KEXTs. Please:

  • was a VirtualBoxVM running at the time of the panic?

Take a Console view of all messages from before the panic. In your case, is the following message present?

Code: Select all
kernel[0]: aio_queue_async_request(): too many in flight for proc: 16.


If you like, paste to this topic the last few messages from before the bootlog line. Hint: use the full editor, paste as code.

Re: kernel panic when copying files

Post by jthackray » Sat Jan 26, 2013 9:13 am

Hi,

Thanks for your reply. I'd just installed VirtualBox, as this is a brand-new Mac (to me), but
no VM was running at the time (I was only running Chrome, iTunes and iTerm2, with 16GB
of RAM, so it wasn't stressed, there was 11GB of RAM free). Alas, no sign of "too many in flight for proc: 16.".
Here's the console log file just before and after the reboot, but nothing interesting, that I
can see.

Hope you can track down the problem. I was thinking about putting my home directory on
ZFS, as I've had corruption with HFS+ before, but I'm not so sure now. Would love it to be
completely reliable (I purchased the "silver" Zevo historically, but didn't use it very much at
the time).

Thanks,
Jon.

Making things reproducible

Post by grahamperrin » Tue Jan 29, 2013 1:21 am

jthackray wrote:… track down the problem. …


Generally speaking, I guess that it'll be easier for developers of ZEVO to debug (and develop a fix for) a problem if that problem is reproducible.

As end users, there's the wish to avoid (not reproduce) kernel panics. But if another kernel panic does occur: whilst OS X restarts itself, take as many notes as possible about things that were going on in the minutes, seconds or moments before the panic.

With system.log et cetera written to HFS Plus, we can't be certain that the last messages saved to disk were truly the last messages before the panic – so handwritten notes may include a hidden gem. (My own note-taking is not as rigorous as it could be.)

Like you, I purchased Silver but my use of that edition was relatively restrained.

Personally, I took an early and deep plunge into ZEVO – for my home directory – with Mountain Lion, before the OS was released, at a time when a Mountain Lion-related panic was both (a) very easily reproducible and (b) equally easy to avoid. The fix was released in extraordinarily good time – 1.1.1 built around nine days after 1.1.

Please, which version?

With Chromium issue 160274 some users may be unaware that Chrome is outdated … and certainly at least one past version of Chrome causes kernel panics.

> Chrome, Please, which version?

26.0.1397.2. Doesn't look like the cause of the kernel panic. And the backtrace said:

Kernel Extensions in backtrace:
com.getgreenbytes.filesystem.zfs

> Personally, I took an early and deep plunge into ZEVO – for my home directory

I _really_ would like to use it for my home directory, but I just don't think it's reliable enough yet, which is a shame. And also, I require Mail.app to be searchable, so I can easily find mail which comes from Exchange, and I believe that requires HFS+. Again, a pity.

Maybe I might put $HOME on HFS+ and then symlink into a ZFS filesystem, but that requires knowing in advance roughly how much space to allocate for each partition. Would be great if ZEVO and MacZFS merged, so I could have some guarantees that in (1,2,3) years' time I won't end up with an unsupportable system (e.g. when OS X 10.9 is released, knowing that the kext will still install and run reliably)

Mail.app

Post by grahamperrin » Tue Feb 05, 2013 9:29 am

No problems with Mail here. Works fine with ZEVO ZFS. The list of things that may be imperfect with ZEVO is fairly short …

Jon, please, can you reproduce a panic of this type with OS X 10.8.3, Build 12D78?
