How easy is the lvm system to deal with in less-than-ideal situations?
I'm especially interested in catastrophic failures.  If I lose a
physical drive (head crash, for example), how would I go about
recovering?  How would I even know which files I've lost?

Also, if I'm lucky enough to get some advanced warning of a drive going
bad, how easy is it to move files from one PE to another?  If I've
already lost a couple (physical) blocks, how do I separate out the good
files from those that are corrupted.  In other words, assuming I know
which blocks on the drive are suspect/bad, how do I then find out which
files in the corresponding physical extent are actually using those
blocks?

I've read the man pages and played around a little with loop-ed files so
I know the basics of the lvm system.  I wasn't able to figure out what
to do in these sorts of circumstances however.

TIA for answers (or ptrs to answers)..
