I'm the developer of parallelknoppix, which is a live CD that sets up
HPC clusters quickly, using a terminal server to PXE boot slaves using
the cd itself as the slave's filesystem. I had ganglia 2.5.7 working a
while ago, and it's partially working in the current version. If anyone
could give me some help getting 3.0.2 working, I'd appreciate it.
Packages can be installed while running the live CD, and configurations
changed, since it uses unionfs. I think the problems with ganglia in
the current release _may_ be due to unionfs, since /var is a symlink to
/UNIONFS/var, for example. Maybe that's causing the RRDs not to be
properly written.
So if anyone could find a means of installing ganglia 3.02, and get the
web frontend working, and then send me the gmond.conf, gmetad.conf, I'd
really appreciate it. I've tried using the 3.0.2 *.debs that I've found
at ftp://ftp.sara.nl/pub/outgoing/ Everything seems to go ok, but
telnet localhost 8649 doesn't show any output. On the other hand, it
does show output when run chrooted into the filesystem that is used to
create the live CD. Thus, I'm guessing that the UNIONFS layer is causing
problems.
To try this, you need to download the cd image, burn it, and boot it.
The messing around would require no remastering, since as I say, you can
install packages and change configurations while running the CD. So if
anyone would like to try it, the cd image and more information about
P-KPX is available at pareto.uab.es/mcreel/ParallelKnoppix
Thanks in advance, Michael
