Dear Ed. > Does documentation exist describing how to convert a simple, single disk > non-RAID CentOS 5 system to software RAID1 using the CentOS install CD/DVD > as a rescue disk? > > (Assuming not) Is there a need for such? > > (Assuming need) I volunteer to produce it. Maybe you could get in contact with Phil Schaffner who is currently writing a SoftwareRaidonCentOS HowTo: http://wiki.centos.org/HowTos/SoftwareRAIDonCentOS5 We should first clear this up a bit.
