[GLLUG] problem installing Fedora on RAID device

[bridget at vfemail.net]

Hello GLUGers,

Does anyone know why I might be having problems installing fedora on a  
computer with a raid device? I inherited the computer which already  
had fedora 13 installed and working fine except when it came to trying  
to update it. I was told by the system that it could not update  
because the boot was on RAID dm-1 (don't know exactly what that means  
but suspect it has something to do with the configuration of the  
disks) So I decided to try a fresh install of Fedora (20) from a live  
CD, however I could only install it in basic graphic mode and it does  
not work properly, it is slow and jerky and I can not install any  
applications or update anything (eg flash plug ins). If I install it  
in normal mode it does not load properly after re-booting, just  
freezes. If anyone has any ideas as to why this is so I would greatly  
appreciate hearing from you. The RAID device is a mirrored 298GB disk  
with a SATA controller.

Thanks in advance
Bridget
