Software RAID-1 for Red Hat Linux: msg#00127

Subject: Software RAID-1 for Red Hat Linux
Hi :

Has anyone managed to successfully configure software RAID-1 on two
identical
IDE disks ? Here is what I need :

1) A method for creating RAID-1 during installation that is filesystem
independant. In
    otherwords , these steps will 'mirror' an entire disk onto the other
disk while your
    system is being installed as well as while it is being used foreveryday
work , irrespective
    of how you have set up your Linux filesystems on that disk.

2) How do I create a disk 'failover' mechanism so that if during system
operation the 'primary' disk
    fails , the system will automatically switch to the second disk , and
once the 'primary' disk has been
    replaced or repaired , the system is intelligent enough to know that the
newer data is on the backup
   disk , and will use this backup disk to synch the data across all of the
raid devices ?

Regards , Jason
