FreeNAS Notes Revision as of Sunday, 20 December 2015 at 19:56 UTC
__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.
