Hi,
I have Linux Redhat 7.3 configured with software raid1.
I removed second disk from all mirror raids.
Now, lilo quits without showing any error messaes.
If I add second disk to raid for /boot, then lilo will start working fine
again.
My questions are:
1. How can I change my raid1 configuration to have only 1 disk and working
without any problem?
2. How can I change raid1 to non-raid?
Thank you for your help
Mehrdad.
