Setting up LVM with full disks...
I'm new to LVM, and am wondering if it's possible to initialize partitions with data on them as physical volumes, assign them to a volume group, then make a logical volume that covers all the physical volumes, and be able to mount it and still see all the data? (I know, run-on sentence) You can probably see my dilemma. Is there any other way to implement LVM without having to do mass data transfers?
Also, being new to LVM, I'm trying to understand if there would ever be a case that would require you to create multiple volume groups? I mean doesn't it make more sense to just create multiple logical volumes instead? BTW, I'm just running a home file/ftp server with multiple disks.
Thanks for any help or advice,
