suggestions for installing CentOS 5 via USB?
by Rogelio 19 Jun '09

19 Jun '09

I'm having problems installing CentOS via a USB drive. First, I tried using Unetbootin, but with no avail. The 8MB netinstall doesn't work, and the big DVD image doesn't work either. http://lubi.sourceforge.net/unetbootin.html Then I tried this http://www.pendrivelinux.com/usb-centos-5-live-install-via-windows/ with a CentOS DVD file, and that did not work (just hangs). I tried to use the live cd, but then found out that I cannot install the OS with the live cd (like you can with Ubuntu). I don't have easy access to Linux or spare computers, so I used my Windows laptop to dd to the USB. ********************************************** C:\installs\dd>dd if=c:\installs\CentOS-5.3-i386-bin-dvd.iso of=\\.\Volume{5a5e4 fb1-b53a-11dd-b7f4-001492190322} --size --progress bs=1M rawwrite dd for windows version 0.5.

Any suggestions?

NAS Storage server question
by Coert Waagmeester 19 Jun '09

19 Jun '09

Hello all, At our office a have a server running 3 Xen domains. Mail server, etc. I want to make this setup more redundant. There are a few howtos on the combination of Xen, DRBD, and heartbeat. That is probably the best way. Another option I am looking at is a piece of shared storage, a machine running CentOS with a large software RAID 5 array. What is the best means of sharing the storage? I would really like to use a combination of an iSCSI target server, and GFS or OCFS. But the iSCSI target server in the CentOS repos is a 'technology preview' Have any of you used the iSCSI target server in a production environment yet? Is NFS and option? Kind regards, Coert Waagmeester

PERC6 driver on CENTOS 5.3
by mcclnx mcc 18 Jun '09

18 Jun '09

We have DELL R900 server with PERC6/i and PERC 6/E in it. O.S. is CENTOS 5.3. I download latest PERC 6 driver from DELL site and tried to installed it. I have error messages said : Module version 00.00.03.21 for megaraid_sas.ko is not newer than what is already found in kernel 2.6.18-128.1.10.el5 (00.00.04.01-RH1). Does CENTOS 5.3 come with PERC6 driver? I knew in CENTOS 4.X PERC 5 or PERC6 driver is not include. Thanks. ______________________________________________________________________________________________________ 付費才容量無上限？Yahoo!奇摩電子信箱2.0免費給你，信件永遠不必刪！ http://tw.mg0.mail.yahoo.com/dc/landing

intel nic vanished with 5.3
by Tom Brown 18 Jun '09

18 Jun '09

Hi I have boxes with a quad card that shows up with e1000 e1000_probe: Intel(R) PRO/1000 Network Connection However since rebuilding a box from 4.7 to 5.3 this card has vanished - I would have thought this card is pretty generic so i dont believe there are not drivers for it - Any other thoughts? It does not show up at all in messages etc, and ethtool knows nothing of it either. thanks

- Make an automatic install bootable CD
by Kévin COUSIN 18 Jun '09

18 Jun '09

Hello, I tried to make an automatic install bootable CD, with a kickstart file. I use this command to create my CD : sudo mkisofs -v -r -T -b isolinux/isolinux.bin -c isolinux/boot.cat -J -o InstallCD.iso -no-emul-boot -boot-load-size 4 -boot-info-table -hide-rr-moved . I copied all the contents of the CD #1, on a InstallCD dir, on copied my ks.cfg file into the isolinux directory. When I try to boot it, it says " This is not a CentOS CD, please intsert an CentOS CD" Anyone can help me? -- Regards ---- COUSIN Kevin Linux Administrator Global Service Provider 75017 PARIS FRANCE
