Autodetecing RAID members upon boot... need to update initrd?
Hello fellow CentOS'ers-
I've got a system running CentOS 5.0. The motherboard has two onboard SATA ports with two drives attached. I installed the system on a RAID1 setup. However, I'd like to add a hotspare disk to the array. Since there are no additional SATA ports, I've installed an additional controller. After partitioning, the additional drive was easily and successfully

I'm going to guess that there are no IDE drives that have 4096 byte
physical sectors, but it's worth confirming you don't have such a
drive because the current partition scheme you've posted would be
sub-optimal if it does have 4096

Booting USBdeviceB [as root} from USBdeviceA:booter ?
My previous question: "can syslinux on a USBstik also boot installations
on other USB devices ?" got no proper reply, so I'm now including more
background detail.
The new problem is that my 32bit partition of ETHOberon, only gives
a proper font-size under Debian7:DVDinstaller:rescueMode, since I'm
forced to use a laptop, after my previous systems were stolen.

CentOS 5 grub boot problem
I am trying to upgrade my system from 500GB drives to 1TB. I was able
to partition and sync the raid devices, but I cannot get the new drive
to boot.
This is an old system with only IDE ports. There is an added Highpoint
raid card which is used only for the two extra IDE ports. I have
upgraded it with a 1TB SATA drive and an IDE-SATA adapter. I did not
have any problems with the system

is it possible to resive a PV in LVM and add more LV's ?
Hi all
I have a remote server (i.e SSH access only) which was incorrectly
partitioned and I urgently need to get it up and running. It's got a 500GB
HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This
is on LVM, btw.

Trying to boot a SSD of 500GB
Hi,
I have a custom linux system that runs off a FAT32 usb flash disk. I
use syslinux to make it bootable and load the kernel.
I'm trying to boot now from a SSD SATA disk (500GB) but it's not
working and I can't figure out why. BIOS show that no bootable disk
were found.
What I already tried (linux fdisk):

CentOS 5.3 and NTFS
Aaaaaa, I'm pulling out my hair over here!
I have an external USB drive which I had at work, connected just fine
to my CentOS 5.3 box. I recall there was some jiggery-pokery
involved, but do not recall just what.
So now I'm on my wife's freshly installed CentOS 5.3 laptop trying to
get it going, and I keep getting errors about

CDRW-DVD Mount Problem, Centos 5.1, Intel board...
