Thank you for commenting on this Greg. I might look deeper into perceus
as an option if rhel (and particularly variants as in Scientific Linux)
work well. Our infrastructure will most likely include nfs-root,
possibly hybrid and full-install. So if Perceus can support it with a
few simple VNFS capsules then that should simplify administration greatly.
Would you declare Perceus as production quality? Or would our
production infrastructure be a large-scale test? (Which I'm not sure if
I'm comfortable being a test case with our production clusters ;o)
Thanks,
Eric

Not to diverge this conversation, but has anyone had any experience
using this pxe boot / nfs model with a rhel variant? I have been
wanting to do a nfs root or ramdisk model for some-time but our
software stack requires a rhel base so Scyld and Perceus most likely
will not work (although I am still looking into both of them to make
sure)
I haven't made any announcements on this list about Perceus yet, so just
to clarify:
Perceus (http://www.perceus.org) works very well with RHEL and we will
soon have some VNFS capsules for the commercial distributions including
high performance hardware and library stack and application stack
pre-integrated into the capsule (which we will offer, support and
certify for various solutions via Infiscale (http://www.infiscale.com).
note: Perceus capsules contain the kernel, drivers, provisioning scripts
and utilities to support provisioning the VNFS into a single file that
is importable into Perceus with a single command. The released capsules
support stateless provisioning, but there is already work in creating
capsules that can do statefull, NFS (almost)root, and hybrid systems.
We have a user already running Perceus with RHEL capsules in HPC and
another prototyping it for a web cluster solution.
Also, Warewulf has been known to scale well over 2000 nodes. Perceus
limits have yet to be reached, but it can natively handle load balancing
and fail over multiple Perceus masters. Theoretically the limits should
be well beyond Warewulf's capabilities.
Version 1.0 of Perceus has been released (GPL) and now we are in bug
fixing and tuning mode. We are in need of testers and documentation so
if anyone is interested please let me know.
