Another LVM question. If I want to remove a drive and tell pvmove to
move the data off it, can the drive have files being written to it
while this is done? I'm wanting to use my old spare drive to move some
things around but right now LVM has it. I think it is OK but just want
to make sure. If it is not OK, do I have to unmount the LV first?
Once you start pvmove running, LVM will not allocate any more space on
the drive, so any files written to the LV will go on another drive.
If you mean you want to write to it separately from LVM, of course you
can, as long as you are using a different partition.
I think we have a problem:

So, I got space left on sdc but it won't move the data off sdb. Did
this run off into the ditch? :/
