Message-ID: <5.0.2.1.0.20030103170426.00b12dc0@pop3.gbnetworks.com> Hi All, forgive me if this cross-over question is partly due elsewhere - I really do need some assistance here, or advice at least. Flame me at your leisure! I have the following setup in mind: I just ordered the basic Scyld-Beowulf CD from Linux Central to start testing next week, and I have inquired a number of quotes for a 2-server mountrack situation, with RAID-1/5+ Hotspare configuration, on SCSI (probably Adaptec) RAID-controllers and drives. I am planning to run Red Hat Linux 8.x as an OS, on which I presumably can install all the necessary Scyld RPM's, or at least update the software that comes with the (2001?) Scyld CD from linux Central. The plan is to run a 2-server fail-over config running as a primary daemon either FreeRadius or IC-Radius, which processes I plan to manage with the cluster software from scyld. If it can be done I do not know - but the docs suggest it may. The Radius will obviously do accounting and Authorisation / Authentication for Radius clients coming from our link, and I will have a MySQL database on both servers that will replicate the data involved. Now I'm not the expert here, and would love any comments or pointers you may want to give me - I am sideposting on all kinds of lists right now with various questions, but the more the better I guess. I will feedback my experience to anyone who may be interested, or write a readme afterwards. If that means I am trying to re-invent the wheel, please let me know. thanks so much folks!

Scyld CD from linux Central. Two points: That's a very old version of the software.

The professional version of the software includes the user-level tools and documentation that makes it much easier. -- Donald Becker becker@scyld.com Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 From becker at scyld.com Wed Jan 15 10:41:01 2003 From: becker at scyld.com (Donald Becker) Date: Tue Nov 9 01:14:27 2010 Subject: [scyld-users] Re: both fast and gigabit ethernet on a Scyld cluster In-Reply-To: <200301151423.h0FENpee001511@ida.astro.unibas.ch> Message-ID: On Wed, 15 Jan 2003, Hans Schwengeler wrote: > Subject: both fast and gigabit ethernet on a Scyld cluster .. > In fact I needed to type 'beoserv -f /etc/beowulf/config.giga' (instead of > 'beoserv -c ', but it got me going a bit further. Ahhh, that's right: the old versions of the programs had sometimes inconsistent options. The "-f" option made more sense for the 'beoserv' program, but we changed to a consistent set of common options with the '28' series. > Now it booted into stage 3 but exited bproc because of 'connection refused'. > After some time I realized I had also to start a bpmaster process tailored > for the gigabit-ethernet (bpmaster -c /etc/beowulf/config.giga). > I had to kill the old process because bpmaster refused to start when > onother one was running. After this, the single-processor nodes came up > just fine. I should have been more clear with my suggestion. You created a new cluster operation configuration file, leaving the standard configuration file only for cluster boot. Instead the new configuration file should be for the stage 1 boot only. /etc/beowulf/config.stage1 Since all of the other programs default to using /etc/beowulf/config that configuration file should reflect the current cluster state. > This "hand"-booting seems to be a bit ackward. maybe you have a better > solution. But a least all the nodes are now up for the moment which is great. This has become a surprisingly common configuration. It's now pretty much typical to have a PXE boot and management on a Fast Ethernet port, but want to operate the cluster over Gb Ethernet. The 100Mbps Ethernet is typically integrated on the motherboard and supports IPMI or Wake-On-LAN. The Gb Ethernet rarely has PXE boot, and I don't know of any Gb chips which support management. We have ad hoc solutions for this with both the 27 and 28 series releases. In the past few months we have changed the underlying programs to avoid replicating servers for split networks. Our 29 series will have a GUI configuration checkbox to automate the (now trivial) configuration file setup. Using two networks turned out to have significant implications for our new scalable flow-controlled PXE boot server. The server has to explicitly track which interface initial PXE request arrived on and handle them differently than later information requests. It's easier to add the support now, when there are only a few users, than after the release. -- Donald Becker becker@scyld.com Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 From jameseggleston at hotmail.com Fri Jan 17 14:10:01 2003 From: jameseggleston at hotmail.com (James Eggleston) Date: Tue Nov 9 01:14:27 2010 Subject: [scyld-users] Install problems Message-ID: An HTML attachment was scrubbed...

That usually indicates a media problem, or an IDE controller problem You can switch to the text consoles with Ctrl-Alt-F1 and Ctrl-Alt-F2/F3/F4 to see an error report. -- Donald Becker becker@scyld.com Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 From becker at scyld.com Sat Jan 18 13:39:00 2003 From: becker at scyld.com (Donald Becker) Date: Tue Nov 9 01:14:27 2010 Subject: [scyld-users] Install problems In-Reply-To: Message-ID: On Sat, 18 Jan 2003, James Eggleston wrote: > ?im using the newest version (2.0), Which version? Our old version series is 27, with a typical verison for x86 being 27Cz-9. That old series predated the Xeon, and may not work with "Pentium 4" systems. The current series is 28, with most customers using 28Bz-4 or 28Cz-4. This series has been tested with about a dozen Pentium 4 and Xeon systems. -- Donald Becker becker@scyld.com Scyld Computing Corporation http://www.scyld.com 410 Severn Ave. Suite 210 Scyld Beowulf cluster system Annapolis MD 21403 410-990-9993 From wade.hampton at nsc1.net Mon Jan 20 13:58:00 2003 From: wade.hampton at nsc1.net (Wade Hampton) Date: Tue Nov 9 01:14:27 2010 Subject: [scyld-users] Maui for Scyld Message-ID: <3E2C416D.9080206@nsc1.net> G'day, Has anyone made a bproc interface for Maui that is compatible with Scyld? -- Wade Hampton
