Hi all, I'm trying to setup a RAID-1 with Centos4.2 on HP Netserver E60. The raid consists of 2 9,1GB SCSI disks. The partitioning and installation process went smoothly, but after it finished and rebooting, there is an error: Missing operating system. The partition is: / /home swap Bootloader is on device md0. What could be possibly wrong?

Hello. It is a bug in grub: https://bugzilla.redhat.com/bugzilla/long_list.cgi?buglist=114690 To solve: 1) Boot from first CD of CentOS 'linux rescue'. 2) From shell start 'grub' 3) From grub execute the following: root (hd0,0) setup (hd0) root (hd1,0) setup (hd1) Reboot Miguel R.

I'd just add that you might also consider having small /boot on separate partition (and make it the very first partition on the disk). 100-200MB should work perfectly fine. Since your drives are relatively small, it won't make much difference (I guess your / is well within first 8 gigabytes). On larger drivers you could have issues (depending on BIOS) -- for example everything works, than you upgrade the kernel and can't boot anymore (new kernel and/or initrd image ended somewhere on the file system above first 8 gigs). It would also give you more options on how you want to create your / (for exmaple, RAID-5, RAID-10, on logical volume, etc). ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.
