I currently have a Debian Lenny file server for my small network (4 machines). I have 4x1TB drives in a RAID5 config. Since I botched the Lenny-Squeeze upgrade, it seems like a perfect time to give ZFS a try.
I'm debating between NexentaStor and FreeNAS. I'm leaning towards NexentaStor since it uses the original ZFS implementation, as opposed to a port, but I wonder if I miss out on some awesome feature if I go that way.
I don't want to stay with Debian because it's more more shell I have to worry about maintaining. I'm very happy with a coLinux install that fullfills all my hacking needs.
Your input is greatly appreciated.
