Is pfSense sensitive to dirty shutdowns/reboots?
As the title says…
Both my pfSense and WHS2011 boxes are protected by a single UPS (APC Back-UPS RS500) with one USB port for automated shutdown. However, it also means that it can only control one of the boxes. I chose this to be the WHS2011 server for obvious reasons (terabytes of data).
That said, will it be too much of a big deal for pfSense when the UPS goes to sleep abruptly?
The pfSense is not doing anything fancy other than Squid3 + SquidGuard3, DHCP, DNS, etc.

I had several times problems with squid
Until I found that it happens because of improper shutdown of the computer
Especially with squid
I plugged the computer of pfsense to ups
There is a power outage
I turn off the computer
And turns it back later
You can use the NUT package in pfSense and a NUT windows client to safely shutdown both machines. You could probably do that with the ups connected to either box physically.
Thanks for the responses.
I'm currently looking at NUT at work but I can't make heads or tails of it. Maybe a few more hours would help me digest everything.

Have you had a look at apcupsd?
I have it running on a Windows virtual machine. When the on-battery level drops below 50% it tells ESXi, via ssh/putty, to first shut down all the VMs gracefully (including this apcupsd VM) and then to shut down itself (ESXi).
I reckon you could have WHS ssh to the pfSense box and shut that down then shut itself down.
The Windows version of apcupsd makes life a bit easier than NUT if, like me, you find Unix/Linux command line stuff can be a bit of struggle.
^ That is indeed promising. I've forgotten completely about apcupsd. I used this on a ClarkConnect box several years ago.
Thanks for reminding me.
If you are on NanoBSD (e.g. CF) then it's not particularly sensitive.
A full install without any extra packages probably wouldn't have any problems either.
If you have packages with a lot of volatile data on the HDD such as squid, then you might have problems.
