[mythtv-users] installing boot drive need suggestions to get recordings from lvm group to new drive

[Vinton Coffman]

I have one 120 GB drive with /boot, /,  swap and a lvm volume group  
for /home that spans a second 120 GB drive with all partitions using  
ext3.  I just bought a 400 GB drive that I want to move everything on  
to.  I want to use the same partition scheme: /boot and  / using  
ext3, swap and a lvm for /home using jfs.

Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/hda3              5036316   4125580    654904  87% /
/dev/hda1               295564     22456    257848   9% /boot
/dev/mapper/Volume00-LogVol00
                      224079412 214764708    208644 100% /home

The system started as RH9 and was upgraded to FC3. I'm going to do a  
fresh install of FC4 to get the new partition and filesystem scheme.  
I'll need to extract the database using the instructions in the  
mythtv docs.  But what is the best way to get the recordings from the  
old lvm volume group for /home?

Do I need a intermediate drive to connect to the current fc3 system  
and copy /home to a standard ext3 partition that I can then mount to  
the new fc4 system and copy from?

or

Do I follow the LVM Howto recipe for "Moving a volume group to  
another system?  Then copy the recordings.  I don't want to keep  
these two 120 GB drives in the system.  I plan to put them in  
firewire cases and use the as backup drives for my powerbook and ibook.

Suggestions to make this process less painful would be greatly  
appreciated.
Thanks,
