do you realize that if any one of those 4 miscellaneous drives fails, 
you lose the whole volume?

got backup?   if you do, then just wipe and rebuild your LVM and restore 
the backup.

if you don't, well, you better start thinking about what you do when one 
of those drives fails and takes out all your data.
