ZFS Read-only Implementation
ZFS on OSX is implemented as a readonly filesystem by default. This
means that only the ZFS subcommands that do non write operations are
permitted. Permitted subcommands are list, get, mount, unmount, and
send.
A full ZFS implementation that allows all subcommands and is read/write
is available for download at URLﾘﾝｸ(developer.apple.com)
To determine which version of ZFS is loaded(readonly or writable):
# kextstat | grep zfs
com.apple.filesystems.zfs.readonly is the readonly kext version.
com.apple.filesystems.zfs is the writable kext version.
