I'm trying to get a crash dump of a ZFS-related kernel crash, but it happens before "dumpon" has run, so i think i need to hardcode the device in the kernel. However, i can't find the syntax for this. Anyone have any ideas? All i've found in the docs is this: "Alternatively, the dump device can be hard-coded via the dump clause in the config(5) line of a kernel configuration file. This approach is deprecated and should be used only if a kernel is crashing before dumpon(8) can be executed." http://www.freebsd.org/doc/en_US.ISO8859-1/books/developers-handbook/kerneldebug.html#KERNELDEBUG-OBTAIN I've also looked at config(5). Thanks, johan
