I am a newb to Linux. Been following FC6 guide at
http://wilsonet.com/mythtv/fcmyth.php but cannot
get my volume group "seen".
Searching and using http://mythtv.org/docs/mythtv-HOWTO.html#toc24.1
and http://tldp.org/HOWTO/LVM-HOWTO/ for answers to where I missed a
step but I am at a loss. Google seemed to point to recovering from a
failed LVM drive
I setup LVM at install when loading FC6 (Fedora) on two 300gb hdd,
using both for Volume Group called "Video_Vol". First HDD is sda
has the system partitions on sda1 thru sda5, second HDD is sdb
with partition sdb1, and third HDD is sdc with partition sdc1. The
second and third HDD are the Volume Group called "Video_Vol".
I am not certain of what nor how to get the VG "seen". Any pointers
would be appreciated. If I am posting to the wrong list, please,
let me know and I will move on.
