Migrate file server from OpenIndiana to NAS4Free

OpenIndiana is my good friend for the past several years. It works nicely, but I’ve decided to move on it to NAS4Free.


To catch it up current hardware especially 4k block device such as recent 4TB HDD, SSD, and so on. Yes, I know that OI supports 4k devices to set ashift=12, but I cannot make good result. In addition, I seem that the development of opened solaris eco-system goes more shrink and slow than before. I believe that OpenIndiana and Illumos is fabulous and well sophisticated operating system even now, but I also have to take it suit for current hardware in order for me to choose most cost effective hardware. I need actively working development community in addition to well stabilized operating system. So, I decided to choose another way.


Fortunately, ZFS of OpenIndiana can be moved to FreeBSD with zpool export and import. So, I’m going to seek some nice FreeBSD distribution for some file server work and found that NAS4Free is good choise for me.

NAS4Free on HP Microserver

I’ve booted NAS4Free from cdrom and installed into 2gb usb stick. It works super easily and perfect. After installation, I’ve imported exported zpool from OpenIndiana and NAS4Free detects and synchronizes it into its repository. I’ve add CIFS and NFS services on the gui and it can be configured super easy and just works !


NAS4Free works so far, so good. I’ll watch it and do additional works(some resource monitoring) for the future. Enjoy !

Rear speaker and enclosure for MCC Smart 450

MCC Smart 450 has poor audio playback environment by default. Major way to upgrade is to install speaker bins under the dash ( see ) and replace speaker to more large one. I’m using Helix’s E5X. But I’m not satisfied with just two front speaker. I’ve used my polkaudio’s pc speaker on the back of sheet and it still lacks performance especially total sound pressure and dynamic range. So I’ve made my owns by DIY.


  • Sealed enclosure with no bracing
  • Enclosure inner volume: approx 14.1inch(W) x 11.8inch(H) x 5.9inch(D) = 0.535 Ft3(15litre)

Parts list:

  • 2x FOSTEX FF225WK - amazon - $200
  • 2x FOSTEX P24B Screw Type Speaker Terminal - amazon - $10
  • 3x 450x900x12 MDF(Medium-density fibreboard) - $30

Time needed: * approx 40 hours(I’ve spent 2 weekends)

Here is my result.Yeah ! 07
