Hi Rick, what do you think about this configuration:
Part all disks like this 7GiB 493GiB Make a RAIDz1 out of the 493GiB partitions and a RAID5 out of the 7GiB partitions. Create a swap, and the root in the RAID5, the dirs with the user data in the ZFS storage. Backup the / daily to the ZFS :) Greetings Cyron > I'm putting together a NexentaOS (b65)-based server that has 4 500 GB > drives on it. Currently it has two, set up as a ZFS mirror.
