I've tried to run manually savecore. I tried before RAID get OPTIMAL and
after that.
dumpmon says:
dumpon -l
raid/r0p3
savecore -vvf /var/crash /dev/raid/r0p3 worked now but... It extracted
another dump from october 2014.
On my box swap used just a little so I blieve that there might be that dump
but where's dump from march,15 2015?
I'd like to figure out what happend with savecore and kernel dumps. Is
there a safe way to test this functional? Some test kernel panics?
