I definitely have dumps enabled on a certain 3.0-CURRENT box (as of Nov
5), yet no dump took place. As far as I know, I let a ktrace run for a
while on a process that did a *lot* of I/O, and then did a 'ktrace -C',
got myself one last '$ ' prompt, and nothing more.
This happened this afternoon, so no go for you simultaneous
unrelated but linked events weirdos :-)
Sorry, nothing more, AFAIK it wasn't even writing to a softupdates
filesystem...
Setting dumpdev in /etc/rc.conf should be enough, no? And that should
(could) translate to the following being visible during runtime:
% sysctl -a | grep dump
kern.dumpdev: { major = 4, minor = 131073 }
kern.sugid_coredump: 0
machdep.do_dump: 1
that corresponds with my swap device (/dev/da0s1b, which is large enough
to contain a complete dump), /var/crash has enough free, savecore did run
according to my syslog (and produced an identical result when run later by
hand).
Anyway, sorry that I can't be of more help... did that NFS patch get
committed? I'd like to try an installworld from an NFS-mounted /usr/obj.
(It should be possible to do the actual build on another machine and then
only install the result on other machines, right?)
