Latest ZFS source code

How to install ZFS binaries

The tar ball will extract a “build” directory. After you’ve made a backup of:

/usr/sbin/zfs /usr/sbin/zpool /usr/lib/libzfs.dylib /System/Library/Extensions/zfs.kext /System/Library/Filesystems/zfs.fs

you can: 

sudo cp build/Leopard_Release/zfs /usr/sbin/zfs
sudo cp build/Leopard_Release/zpool /usr/sbin/zpool
sudo cp build/Leopard_Release/libzfs.dylib /usr/lib/libzfs.dylib

Not sure about cp(1) semantics, so we blow the existing directories away 

sudo /bin/rm -rf /System/Library/Filesystems/zfs.fs /System/Library/Extensions/zfs.kext

sudo cp -R build/Leopard_Release/zfs.fs /System/Library/Filesystems/zfs.fs
sudo cp -R build/Leopard_Release/zfs.kext /System/Library/Extensions/zfs.kext

Also, make sure that all the files are owned by root:wheel after you have copied them over. If not you can do: 

sudo chown -R root:wheel /System/Library/Extensions/zfs.kext
sudo chown -R root:wheel /System/Library/Filesystems/zfs.fs
sudo chown -R root:wheel /usr/sbin/zpool
sudo chown -R root:wheel /usr/sbin/zfs
sudo chown -R root:wheel /usr/lib/libzfs.dylib

Then reboot.

How to compile ZFS source

The tar ball will extract to a top level directory of the same name as the version you have downloaded: eg. ‘zfs-111’. There are two main things you will need in order to build the ZFS source.

  • You will need to have the latest version of Xcode installed (part of the Developer tools).
  • Open the zfs project in Xcode and select the "Leopard_Release" configuration in the build configuration menu at the top.
