Cluster server options?
by Scott Ehrlich 09 Nov '09

09 Nov '09

I have a 10 blade cluster of just hardware - I can install what I want, how I want. What options are there if I wanted to build the 10 blades as one large beast, but _NOT_ necessarily for someone doing grid-type work? Some users don't now how to program that way, but they'd like to have their program run on something that acts like a single processor, but a massive single processor with lots of memory. Some code is designed for a single, powerful workstation. I'd like this cluster to act as one powerful workstation. Thanks for insights. Scott

EL4 EPEL mirrors missing headers
by Ron Yorston 09 Nov '09

09 Nov '09

The EPEL mirrors for EL4 no longer have a headers directory, just repodata. This means that up2date has stopped working. Is this a problem with EPEL or with my system? Ron

GUID Partition Tables and Ext3 Partition Size
by Manish Kathuria 09 Nov '09

09 Nov '09

Hello, Does CentOS 5.4 support large ( > 2 TB) external storage devices using GPT (GUID Partition Tables), while the main OS resides on smaller hard disks using MBR. In this scenario, what can be the largest possible size of an ext3 partition (and filesystem) which can be created on the storage array under CentOS 5.4 ? Thanks, Manish

connection refused resolving - after 5.4 upgrade
by Rob Kampen 08 Nov '09

08 Nov '09

Hi all, prior to 5.4 upgrade, my two DNS servers would only get 'connection refused resolving .....' on rare infrequent occasions (once or twice a month) after upgrade to 5.4 I get 500+ per day. Google has suggestions for |logging category lame-servers null; ; ; |however this strikes me as severe overkill as it will mask genuine problems. Anyone else noticed this? Suggestions as to why or what is causing? Thanks Rob

Net-SNMP interfaces out of order
by Bob Puff＠NLE 08 Nov '09

08 Nov '09

Hello Centos People, I have a CentOS 5.3 box that had a total of 5 ethernet cards in it. It functions to share an internet connection with 4 different subnets. All works fine, except I'm noticing that my MRTG traffic graphs are wrong. Further digging with snmpwalk reveal that the order of the ethernet interfaces changes every time the machine is rebooted to a different order. For example, I currently see: IF-MIB::ifDescr.1 = STRING: lo IF-MIB::ifDescr.2 = STRING: eth3 IF-MIB::ifDescr.3 = STRING: eth4 IF-MIB::ifDescr.4 = STRING: eth0 IF-MIB::ifDescr.5 = STRING: eth1 IF-MIB::ifDescr.6 = STRING: eth2 IF-MIB::ifDescr.7 = STRING: sit0 Why is this not in proper order? Other servers seem to be ok. my snmpd.conf file has little, if anything as far as config. Is there something I need to put in there for persistence? Bob

Problem: NVIDIA C73 & 1440x900
by MIKE - EMAIL IGNORED 08 Nov '09

08 Nov '09

As mentioned in my previous thread, I can't get my Video card: NVIDIA C73 [GeForce: 7100/ nForce 630i] to display 1440x900 on my CentOS 5.4 on my HP Pavilion with monitor Dell E198WFPV. Googing around, I see that others have had this problem with the NVIDIA card. In one case, it was solved by gaining access to card parameters and setting them directly. I can't find a way to do this on my box. One solution might be to just insert another video card in the bus, and ignore the NVIDIA. Would this work? I have a card that I know works. Thanks in advance for your advice. Thanks, Mike.

administering an MS Windows partition under Linux
by Boris Epstein 08 Nov '09

08 Nov '09

Hi all, If I have a dual-boot machine (Linux and Windows) would I have any good tools under Linux that would allow me to look at the content of the Windows boot partition, administer it, clean up the registry, remove viruses if any, etc? The Windows installation seems to be so defective as to be quite useless so I am trying to think of a good strategy for dealing with the situation. Thanks in advance for any and all advice. Boris.
