Thanks a lot for this info ilovezfs, really interesting.
I guess I stuck with 74.3.1 because as far as I could tell it worked reasonably
well (no data loss, 2+ years running), and no one else was talking about KPs
related to it, so I didm't have much to go on.
Adopting zfs-osx seemed a little convoluted and risky, but ran through the
excellent guide here tonight in a test environment and it all went surprisingly
A few things to note for other people following this, it seems that the guide
is a tiny bit out of date, and in places could do with being a little more
The first line, to get Homebrew uses a broken link. The correct command to use
ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"
The part about ~/.bash_profile is a little vague; if you don't have a
.bash_profile under ~, you can create one with 'touch .bash_profile'. Paste in
the export path mentioned, then run '. .bash_profile' to apply the update.
You can then run the zpool command.
The question I have at this point is, if I remove MacZFS 74.3.1 using this
guide, is it simply a matter of exporting my zpool, removing MacZFS, installing
zfs-osx, importing my zpool then updating it, or is there more to it than that?
Thanks again for all your help.
