Solved SWAPINFO and DUMPON -l

Hello fellow FreeBSD community members can you please help?

I was thinking is there a way to break up swap and dump for when you have swap set up on a usb drive? For example within the fstab file maybe use a different swap for dump?
 
my system does not use rc.conf

# THIS FILE DOES NOTHING, DO NOT MAKE CONFIG CHANGES HERE
 
No that didn't fix it. What about a cron @reboot root dumpon /dev/ada0s3b or something like that? I mean that should fix it right? Swap on a different /dev/da0 and dump set to save locally. Should work right? I mean it shows on reboot now.
 
I don't really want to admit that :( but yes it is PFSense most of everything I get help on is from here for really complicated stuff. Sorry
 
I even
ran

ln -fs /dev/ada0s3b /dev/dumpdev

It still shows no report when I manually crash it
sysctl debug.kdb.panic=1

again my swap is on a usb drive
Goal is dump goes to a different swap

Try to do this setting above in a new file /etc/rc.conf.local
dumpdev="/dev/ada0s3b"

But perhaps it would be more interesting to ask for support on the PFSense forum.

I do ask for help but times I get no response for stuff or the people that do respond are very busy so it can take hours for a seasoned response from someone.
 
I got it working.

Here is how you do it just in case you ever wonder.
1. create a cron job that is specfic to the location you want the dump to go
@reboot root dumpon /dev/ada0s3b
2. cp /etc/rc.dumpon /etc/rc.dumpon.old
3. edit the rc.dumpon file to just be this

ln -fs /dev/ada0s3b /dev/dumpdev
echo "OK ADAPTED ADA0S3B ONLINE"
return 0

they do not use rc.conf at all it needed to return that zero to the program that calls rc.dumpon so that it can parse the dumpon location to it.
