I recently built a new NAS server using FreeNAS after searching to see if anyone had done the things I wanted to do with the server and because I liked the things ZFS does. Now I find that the latest version of FreeNAS does not allow some of the things older versions did or if it does nobody on the FreeNAS forums can tell me, or at least is willing to tell me, how to make it work.
In any case I would like to move back to Ubuntu but keep the ZFS Pools I created in FreeNAS. Unfortunately it seems that the version of ZoL which is available in Ubuntu does not offer the same features (device removal, obsolete counts, and zpool checkpoint) so I would only be able to import the Pools read only at best.
ZoL 0.8.0 seems to have those feature but its only on RC3 and I am worried what the implication might be to install it as far as stabily and bugs go. I also wonder how I go about installing it. Can I install from the the tar.gz or do I need to compile it?
As a side note, the main thing I could not get working on FreeNAS was passing traffic from various Jails through an OpenVPN Jail so that I didn't need to install OpenVPN on all of the Jails that required it.
