Re: [CentOS] network interface question
eth1 exists because the /dev device was found on boot (you have 2 or more network interfaces). eth12 does due to you not have 13+ nic's or did not map a network device to be eth12.

Re: [CentOS] Raid 10 questions...2 drive
RAID10 requires at least 4 drives does it not? Since it's a strip set of mirrored disks, the smallest configuration I can see is 4 disks, 2 mirrored pairs stripped.

Raid 10 requires 4 drives. First you would make two RAID 0 arrays, then create a third array that is RAID 1 using the two RAID 0 arrays for it's devices. This would be a RAID 0+1, stripped set's mirror together. RAID 1+0 is mirrored disk sets stripped together. http://en.wikipedia.org/wiki/RAID#Nested_.28hybrid.29_RAID With only two drives, your option is RAID 1 (mirroring - proper redundancy) or RAID 0 (striping only - lose one drive and you lose *all* data). -- 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 -- Jacob Bresciani Linux Systems Administrator Advanced Ecommerce Research Systems / Terapeak Cell: 250 418-5412 ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

Re: [CentOS] Dell R605 w/ Perc 6/i problem
this sounds like the right solution, you can do this either form the firmware or the megaraid command line tool MegaCli64 (MegaCli for non-64 bit systems) On 2010-06-30, at 7:18 AM, Eero Volotinen wrote: 2010/6/30 mark m.r...@5-cent.us: Jacob Bresciani wrote: R605 is a power edge server model I think.The Perc6/i is a Dell rebranded raid controller, it's actually an LSI in disguise.

Hmmm, I think I see the Linux/CentOS megaraid load as it comes up to the install screen (before I get to look at partitioning). Also, when you boot the R605, you should be able to get into the Perc's firmware for drive creation/maintenance. You might want to check there to see how it thinks things are configured and it hasn't decided the 750G drive is a hotspare or something (a hotspare wouldn't show up to the OS). As far as I can tell, it doesn't think it's a hot spare. Using the firmware configuration utility, it sees the physical drive, and that's it. you need to export drive as jbod or raid0 if you want to use it on os. this is typical on hardware raid controllers. -- Eero ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

However, no matter what I do, the BIOS doesn't see it, and when I boot to linux text, fdisk only sees the raided 1t. Clues for the poor? I want to put the system on the SATA drive, leaving the raid for data. I have no idea what R605 is, but you need to state the version of Centos (imagine that) and the type of disk controller, i.e., post lspci It's possible the problem is a BIOS setting, e.g., you may need to turn on AHCI. -- Enjoy global warming while it lasts. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

[CentOS] ls -l output
OK, this should be an easy fix but I can't find it, and it's strictly a cosmetic's issue. on our older Gentoo systems if you do an ls -a it orders the results with all the . files ordered alphabetically then all the non-hidden files alphabetically. it also sorts with capitals first. on the new Centos 5.3 systems ls -a returns all the files sorted alphabetically with capital's and smalls being equal and the . at the start of a hidden file appears to be ignored. There are no alias's in place on either system. eg.) Gentoo: $ ls -a . .. .Xauthority .bashrc .omega Documents alpha scripts Centos: $ ls -a . .. alpha .bashrc Documents .omega scripts .Xauthority I'd prefer to see things the Gentoo way.
