I built a home NAS server running NetBSD 5.1 back in Sep. 2010 with Gigabyte D525(Atom) with 4GB RAM and 4*2TB HDs. I configured RAIDFrame with RAID5 on 3*2TB and one hot-standby. This provided me with 4TB total usable space.<\/p>\n

I had the root on RAID1(mirrored) raid partition and two(2) 2TB raid5 partions across 3 drives. This had worked very nicely for me hosting all of the data needed for home.<\/p>\n

This also been my NAT box running BIND9, sshd, httpd(apache), dhcpd, ntpd, smtpd, owncloud, samba and etc.<\/p>\n

Now it is end of 2013 and I am running out of the disk space and more importantly, I have not done any of the OS upgrade since NetBSD 5.1(now they have 6.2)<\/p>\n

I want to upgrade the disks with at least 3TBs or even 4TBs but more than anything, I would like to run zfs filesystems with snapshot capability….<\/p>\n

For this, I do not think that staying with NetBSD is not a good idea and the choices that I have are now narrowed down to either FreeNAS or NAS4Free….<\/p>\n

Let’s see what happens….<\/p>\n

Here are some configurations that I would like to save for future references:<\/p>\n
