Hello World !,

I hope someone can help.

I have a Fedora Core 3 box with two hard drives in it. I have enabled software RAID 1 and verifyed that it is working via the mdadm -D command.

Here is the format of the Hardware with software RAID 1:


RAID Devies

/dev/md1 swap 2000.28
/dev/md2 ext3 67499.7
/dev/md0 ext3 502



/dev/sda
sda1 1 64 502 sofware raid
sda2 65 319 2000 software raid
sda3 320 8924 67500 sofware raid

/dev/sdb

sdb1 1 64 502 sofware raid
sdb2 65 319 2000 software raid
sdb3 320 8924 67500 sofware raid


500mb Boot
2000 Swap
the rest for /

Now here is the problem. When I remove one of the SCSI hard drives, the machine does not boot. It gets stuck and a message says " L1".

I was advised to run GRUB and I did and then I recieved the following error: " Error 21"

I am not sure what to do. I've tried doing research and have found no conclusive answer. If anyone out there has any idea how to resolve this, please do not hesitate. Thank you very much all in advance.
