Just a matter of time Recently I started to receive notifications from FreeNAS indicating smart errors on one my hard drives. A quick check of the system log confirms a number of smart errors on /dev/da4.

Wiring Button Pin RPi GPIO 1 GPIO 3 (SCL) 2 GND Power On On my Raspberry Pi 2 Model B Rev 1.1, the system will power on from a halted state when shorting the SCL (GPIO 3) to Ground.
Shutdown When the system is on, the below script will monitor SCL (GPIO 3) for a button press. When a button press is detected, the script will shutdown the Raspberry Pi safely.
Read through the preamble to see what I tried first and why it didn’t work. Or jump ahead to the working install method.
Preamble I’ve been using FreeNAS for a couple of months now, starting with version 9 and later upgrading to version 11. While the experience so far has been great there are a few glaring omissions. First and foremost “monitoring”. There is just no convenient way to monitor the system externally.
I run Plex media server in a FreeBSD based jail. Until now, to connect to the Plex system I would first ssh to the host system. Then I would run jls to find the jid of the jail.
# jls JID IP Address Hostname Path 1 - plex /mnt/vol1/jails/plex I could then connect to the jail system by passing the jid as an argument to jexec with the shell to execute.
My file server is sporting a SuperMicro X10SDV-4C-TLN2F-O motherboard and the case has two Noctua NF-R8 Redux-1800 PWM exhaust fans to keep things cool and quiet. However I noticed that whenever I set the fan mode in IPMI to Optimal, the fans began to pulse.
They slow down, IPMI decides they’ve slowed down to critical levels and spins them back up again. Having no reason to be spinning this fast, they slow back down and the cycle continues again.
