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? 2015-03-16 18:33 GMT+03:00 Konstantin Kulikov : > Hello, > > have you tried to run savecore manually, like > savecore -vvf /var/crash /dev/raid/r0p3 > > Also check that your dump device is working (dumpon -l) > > On Mon, Mar 16, 2015 at 4:40 PM, Michael BlackHeart > wrote: > > Hello there.
