Hi John, Another reason to use SW raid which I have switched too. Although the conversation did generate some really good info. Yea, that Intel RAID is a real POS. - aurf ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Well, I wished I would have made it up as we all ride on the coat tails of some one else's research and findings, but I found it here; http://bugs.contribs.org/show_bug.cgi?id=6181 > me, too ;-) At least, "nodmraid" is not the solution.

That's just ignoring the fake RAID if it is able to detect it. dmraid is meant to deal with this fake RAID stuff, but can't always.

"Intel RAID" covers a lot of sins. Some RAID cards rely on OS software to do much of the RAID: they're jokes, really. If it's a real RAID chipset, no Linux or Windows kernel should even be *AWARE* of the multiple disks, except perhaps for some limited reporting tools. Exactly which chipset are you dealing with?

[CentOS] centos 5.5 install + intel raid
Hi all, Installing 5.5 on a fresh system having an Intel RAID. My 2 drives are configured as a mirror within the Intel BIOS. When starting my install, Anaconda throws an exception. After a brief goog, I see one possible fix is - at the install prompt, type; linux text nodmraid This is fine and all but Centos sees 2 disks at this point rather then 1 which is what I thought the Intel RAID controller would present to the OS. I am pretty much tarded when it comes to installs as I usually boot of a DVD, enter some choices based on requirements and off I go. I once compiled a network driver into the initrd and remade my boot disk but that seems beyond me now. Any help is greatly appreciated. - aurf ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Here are a few cases I can think of where it isn't: * If you've got IPMI piggy-backing on a physical interface, you may not want it to be on an Internet-facing LAN. * If you have a particularly fast ethernet device you need for a storage network. * If you've got a subnet that needs to use jumbo frames but only one NIC supports frames large enough for your application... -- Digimer E-Mail: li...@alteeve.com AN!Whitepapers: http://alteeve.com Node Assassin: http://nodeassassin.org ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
