ZFS Ceases to Work After Update from 74.3.0 to 74.3.3 about maczfs

[GoogleCodeExporter]

Actually now it seems broken altogether! I tried to downgrade and now 
everything is *completely* messed up! Help!

zpool status
internal error: Unknown error: -1
Abort trap: 6

Quite simple.  This is most likely caused by an incomplete upgrade / downgrade.

To know for sure, I would have to look at the actual diagnostic output form the 
diagnostic tool, i.e. the file "collect-maczfs-state-info.txt", mentioned at 
the end of the progress output.

Simple fix:
Make sure the loaded kernel module "zfs.kext" matches the installed zfs tools 
and libraries.
You can check this with "kextstat". The zfs module should show version 74.3.3 
after you installed 74.3.3.

To get you system working, I'd suggest to check the module version with 
kextstat, and then run the installer that corresponds to the active module.
Then export all pools and unload the module.
Then install whatever version you want to use.
Then reboot.
(And in case your pools don't show up automatically, import them once manually.)

Thanks! Uninstalling and then reinstalling the 74.3.0 version did the trick. I 
guess at some point soon I'll reattempt the upgrade after uninstalling 
everything again, including the zfs.kext. The only reason I'm trying the 
upgrade at all is that I've been getting kernel panics with CrashPlan's backup 
service. I'm hoping maybe things will be different with 74.3.3....

Glad to hear it works now.
The differences between 74.3.0. and 74.3.3 are not so big, so chances are the 
newer version doesn't help you.  You could open a new issue for the original 
problem (CrashPlan's crashes) and attach one or two panic reports.  Maybe one 
can say something more definite then.
In any case, if you are on a recent Mac OSX (Mavericks or newer) and don't need 
backward compatibility with older systems, you could also give O3X a try.  O3X 
is an alternative, newer implementation of ZFS running on recent Mac OSX 
versions.  You find the O3X community here:
