Today i installed redhat on one server this server will be used on DR site as a backup.

System has 2 HDD with 500GB space and I created the RAID0 and after that i completed the installation. But after the installation I had to reboot the server but Just after the BIOS screen I got Black screen with just GRUB written.

Raid0 is used

Filesystem Structure

  • /boot 100M (Normally I assign 500M but this time I assign only 100M because the size of /boot rarely increases)
  • swap 8GB

VolGroup0 has two LVMs

  • / has 50G size (LogicalVol00)
  • /u001 has 400G+ size (LogVol01)

I found information on redhat pages. That /boot cannot be used on RAID0

How to install Grub

And boot partition has size of 100M. – OmiPenguin Feb 19 '13 at 7:36
That is not hardware RAID. It is fakeraid. – Michael Hampton Feb 19 '13 at 17:51
@UmairMustafa "Fake" RAID is a system where you can set up the disks in the BIOS but the actual work is done by a software driver. This software driver comes from the BIOS maker and is probably significantly worse than the software raid code that ships with Linux. In this case, your best bet is to reset the BIOS to plain drives and configure software RAID in the RHEL installer. – mattdm Feb 20 '13 at 9:34
