3 kernal panics and large memory use

Post by mjptango » Mon Dec 24, 2012 12:31 pm

hi there,

I have been running the beta verioin 2012.5.9
with an external drive configu with the Setup Assistant - before that I has MacZFS installed.
Never a problem
Now I installed ZEVO CE 1.1.1 and since then I have had 3 kernal panics and memory us of the kernal up to 1.65GB.
1. FIrst I thought ZEVO CE limited the memory use
2. Do I need to unintall anything to stop top the kernal panics.
3. Can I revert back to 2012.5.9

thanks
Michael

Please attach the three .panic files that have com.getgreenbytes.filesystem.zfs in the backtrace.

Were all three before, or after, the update from Community Edition 1.1 to 1.1.1?

What model is the Mac? Make and model of the external drive?

USB, FireWire 400, FireWire 800 or Thunderbolt for that drive?

It should be unnecessary to reuse an earlier edition of ZEVO. Probably far more advisable to use Community Edition.

In the absence of detailed information surrounding the panics, my first instinct would be to consider the possibility of problems with hardware. (For my Mountain Lion case, I recently replaced two cables.)

If you really want to experiment with the earlier edition:

  1. uninstall Community Edition, restart the Mac
  2. use your full installer for Silver Edition, restart the Mac
  3. use the freely available update to the last release of Silver Edition

– but I'd strongly advise considering other things before taking that route.

Hope this helps – Graham

graham,

many thanks for your tips.

1. For some reason the .panic logs cannot be found ( strange, the OS must have deleted them ), so I will need to create news once I have a moment to spare
to deal with kernel panics. Hopefully I can get to this in the next days.

2. When you mention Silver Edition does this mean the beta version of ZEVO as released 2012.05.19

3. FInally is a kernel size of 1.6Gb normal after/during a large copy.
I understood the CE restricted the size of its memory use.

thanks

persistence and existence of .panic files

As a rule of thumb, expect a .panic file to persist for no longer than one month.

SubmitDiagInfo(8) OS X Manual Page

It's also possible for a .panic file to be never written to disk. This can happen if your first start, after a kernel panic, is of Recovery OS.

i'm running on 3.25Gb constantly (according to activity monitor).

personally, with community I didn't experienced panics. with the usage I have (sizes, operations, zfs send / recv etc), I had panics now and then with ZEVO.

with CE it stopped.

Finally here is the kernal panic log file.

After this crash I then uninstalled and then re-installed the 2012_05_19 beta.

It crashed even faster and this time my system would not load the GUI or FS after it booted.

After booting up form an external disk I could look at my HFS disk files.
Eventually I found all the zfs disk drivers and most interestingly an alias to the CE preference pane and Beta verion preference pane
even though I previously had uninstalled the CE version.

There also where two Directories in /System/Libary
one named Extensions the named Extentions with only one su folder in there with a reference
to zfs embeded deep.

So my guess is that either the original MacZFS drivers where active or that there were two ZEVO based zfs drivers
one from the beta and one form the CE version.

I had to reinstall my complete system 10.6.8 to restore my computer back to life.
Since then I have yet to have the time or be brave enough to test again.

One question: if I have formatted my disk with an early beta of ZEVO can I use MacZFS.
I have a server that has several ZFS disks ( mirror raid ) to which I wish to connect my Firewire drive.

Thanks.

Kernel_2013-01-03-093027-Macbook-Pro-2_Panic.txt
includes the following:

Code: Select all
zio_notify_parent: zero io_children [0, 0], err 0


That string appears on page one of a topic where a fix is discussed.

This time a kernel panic with the old 2012_5_9 beta.
I was starting a Time Machine backup - 1st time when I have the KP.

Probably not so relevant as there has been many fixes since then - but I seem to remember back then it was working more stable for me.

Many thanks for the heads up that the CE issue is known and a fix is being worked on.

Still no answer if I can use the MacZFS drivers on a ZEVO formatted zfs disk!

ie uninstall the ZEVO drivers and then install MacZFS 74.
