What is the correct syntax for this - is it like dumpdev="/dev/rda0s1a" (raw mode?) if say /dev/da0s1a is a swap partition? I have 2 swap partitions on da0 and da1 *exactly* the size of memory (262144*1024 bytes). Will this work in a crash, or does the swap partition need to be marginally larger than memory? Finally, is there a simple way to induce a crash in a normal working system, to see how the crash dumps work? > After that, when your machine crashes, the crash dump will be saved into > /var/crash when it comes back up, along with a copy of the kernel which > generated it. These can be inspected later with `gdb -k'. -- Graeme Tait - Echidna To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
