lvm question
 

if one combines a partition from drive 'a' with a partition from drive 'b'
into an lvm partition, what happens if either drive goes bad? is it like
raid 0 where you lose all your data on both?

You cannot have "partitions" spanning multiple disks belong to a Volume Group.
The entire physical device must be devoted to the VG.
A VG is the uppermost abstraction of LVM.

thanks for the details. and what happens if one drive fails?

it depends on how you built the VG.
No md RAID?

it's really fun playing tag and all to get an answer that you obviously have but

tells me nothing other than that there is implicitly a way around the issue at hand
but you're not telling me or anyone else what it is. please elaborate. and

i have no idea what this means. please explain.

thanks,
BabaG
