__NOTOC__

Notes

• Drives from the same manufacturing batches are prone to
  fail together. This is bad. So purchase drives from separate
  websites/vendors to mix things up.
• Be careful with SATA port
  multipliers.
• Love your data? Storage is cheap, and RAIDZ2 is the way to go.
• Picking components is essentially a balancing act of these factors:
  • Low power and/or small form-factor
  • High capacity
  • High redundancy
  • High performance
  • Low $$$
  • Expandability
• Used FreeNAS 8.3
• SMB was significantly slower than AFP.
• Wrote a small
  script to snapshot
  my Macs from the FreeNAS box. Did this by creating a new account,
  setting the home folder in a ZFS filesystem, generating SSH keys,
  putting them on Macs.
  • Runs as a cron job at midnight
  • Script needs full paths to zfs, sudo, rsync, etc.

Hardware

I didn’t care about size. Also wanted a mobo that has as many onboard
SATA ports as possible. Lots of memory since ZFS loves
memory.

• Used nylon 8-32 × ½ Phillips flat-head screws for the fan-filters.

Software

• Mounting:

 # Mount read-write
 mount -wu /
 
 # Mount read-only
 mount -ru /

• Sudoers file is at /conf/base/etc/local/sudoers. You will lose
  changes to this file upon upgrading FreeNAS.
