Re: [BProc] boot.img never comes on clustermatic

[<lo...@tr...>]

I copy down there two messages which made it work..though I am not 
totally sure it's
your problem

I just saw something like this on a cluster here and I fixed it.  If
you're having the same problem, the following patch should fix it for
you.  This only modifies the "beoserv" binary (which runs on the
master and does things like server boot images and RARP responses) so
you won't have to change the slave boot images or anything.

you'll have to rebuilt beoboot.  Grab the source RPM (included in
Clustermatic 3) and apply this patch to it.

You'll have to do something like:

rpm -i beoboot-....src.rpm

rpmbuild -bp /usr/src/redhat/SPECS/beoboot.spec

cd  /usr/src/redhat/BUILD/beoboot-....

patch -p1 < patchfile

make beoserv


Then replace the beoserv in /usr/sbin with the one built there.  See
local Linux guru for more help on building stuff. :)
