issues with dumpdev in /etc/defaults/rc.conf

You could just add it as a shellcmd.

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? It shows when I reboot now YEAH~!~!

Shell Output - swapinfo
Device          512-blocks     Used    Avail Capacity
/dev/da0p1.eli   250066944        0 250066944     0%

Shell Output - dumpon -l
ada0s3b

@stephenw10

even with me running dumpon and setting it and it showing dumpon -l it does not show rc.dumpon will it still work?

stephenw10

Right presumably because you have moved SWAP to that other format where fails the test. But if the raw command shows it it should work fine.

JonathanLee

@stephenw10
Ok I will be right back I am going to trigger it to test it

sysctl debug.kdb.panic=1

JonathanLee

I am just worried it wont see it because of this program

dumpon_try()

	if /sbin/dumpon "${1}" ; then
		# Make a symlink in devfs for savecore

while read dev mp type more ; do

	dumpon_try "${dev}" && works=true
done </etc/fstab

		dumpon_try "${dev}" && works=true
	done

		echo "No suitable dump device was found." 1>&2
		exit
	fi
fi

will savecore see it...

@stephenw10

It does not populate I wonder what else is needed

JonathanLee

ln -fs /dev/ada0s3b /dev/dumpdev

I think this linker file is still needed for it to work I need to generate it manually because the program does it only based on fstab

JonathanLee

still no report /var/crash weird I even manual created the link for devdump

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

This might fix it

@JonathanLee said in issues with dumpdev in /etc/defaults/rc.conf:

sysctl debug.kdb.panic=1

Custom solution

add the cron
copy the rc.dumpon to rc.dumpon.old
add the new info

and it works
