Am really sorry for this. Just a quick update, the ZFS to Linux demo is available right now. The code would be available on and after sep 15th.
The following are the details of the beta release scheduled for 15th sep:
Zpool Version: 18
Solaris Build: b121
Linux distros supported ( 64 bit Only) : Fedora 12 (rpms), RHEL 6 beta 2 (rpms), Ubuntu 10.04 (make from source)
Sorry for the delay by a couple of weeks, we are just into the mode of fine tuning the code before handing it over for testing at your end.
