As it happens, I can cite a perfect example of this from my own
experiences in the last week :)

I have a hard drive in the Fedora server I run in my basement that has
started throwing intermittent I/O errors. Fortunately for me, I set it
up on LVM. I went out, bought a new hard drive, inserted it, added it
to the volume group and then ran 'pvmove' to migrate all of the
sectors off of the original drive to the new one. Once that was done,
I could safely remove the defective drive from the volume group.

Zero downtime, perfect recovery.
