Anybody using maczfs / ZEVO? Have good or bad things to say, in terms of
reliability, performance, features?
My main reason for asking is this: I have a mac, I use Time Machine, and I
have VM's inside. Time Machine, while great in general, has the limitation of
being unable to intelligently identify changed bits inside a VM file. So you
have to exclude the VM from Time Machine, and you have to run backup software
inside the VM.
I would greatly prefer, if it's reliable, to let the VM reside on ZFS and use
zfs send to backup my guest VM's.
I am not looking to replace HFS+ as the primary filesystem of the mac; although
that would be cool, there's often a reliability benefit to staying on the
supported, beaten path, standard configuration. But if ZFS can be used to hold
the guest VM storage reliably, I would benefit from that.
ZEVO's great as long as you don't mind managing everything from the command
line. I had to figure out how to identify the disks, as it manages them a
little differently in MacOS. I had some minor issues hosting iTunes/iPhoto
libraries on ZFS volumes, with it being a little more sluggish & freezing up
slightly. Other than that it worked fine. I'm back on HFS+ for iTunes/iPhoto
now, but I'm hopeful it'll be resolved in a future release so I can switch back
MacZFS will give zpool version 8 & zfs version 2, whereas ZEVO is zpool version
28 &zfs version 5, so make your decision accordingly. I have not tried MacZFS
in a long time, so I couldn't say if it is better or worse than ZEVO.
