Dear Sir First i read about your experience in the Unix Administration, and it is ereal great, hoping one day to reach your point. Second, i have a question concerning the Mirroring technique as i use it here, knowing that i am working with RedHat linux 7.2. My question is: How can i make the slave or the backup disk bootable in case of master disk crash? More exploration: I have 2 hard disks, one is the master and the other is the slave or the backup, or the mirror (whatever), i finished installing them and they are working fine (till now !!), but when i make a test to remove anyone to see if the other will work properly (as this will be the case in case of anyone of them crash), i found that the master one is working fine (which contain the boot commands) while the other failed to boot. I tried to put a bootable disk but it gives me something related to kernel panics. Your help will be much appreciatted: -- Mohamed Farouk System Engineer IT Dept.
