Failover to USB for hard drive crash
« on: December 26, 2017, 10:07:46 am »
Think I know the answer (no) but thought I would throw it out there.  Any way to have an automatic failover to a USB thumb drive in the event of a hard drive crash?  I have a customer who is using pfsense in a business where he has POS devices and really needs a good failover solution.  Had a recent hard drive crash on a NUC Atom 280 build and he was offline for a few hours.  He is running a captive portal for WiFi guests with authentication, but that could be optional for the USB boot.  The owner has decent knowledge of PC's and could easily be walked through a boot from usb sequence.
What else would anyone recommend for failover in this situation?  A complete system standing by?  Is this where CARP comes in?

ZFS with 2 or better 4 drives in a pool.

Everything fails eventually.

A good configuration backup taken regularly and a cold-spare system is a decent alternative.

GMIRROR should ride out most failures of a single hard disk.

ZFS should also help with a disk failure.

Two live units in HA/CARP will generally have zero downtime if a node crashes.
