I can do a resize of filesystem, but I can do a pvmove. I can do a
lvreduce and a vgreduce and the data seems to be OK but it isn't normal
procedure.
How can I quit a pv of a lvm volume ??
See the LVM-HOWTO, section 11.6 "Removing physical volumes from a volume
group", and the section 13.5 "Removing an old disk".
You'll need to reduce the filesystem to the correct size (less than the
LV will be when you remove the PV), then pvmove the drive away,
vgreduce.
Since I don't have the exact specs (size of fs, lv, vg, pv, etc), I
can't give you the exact steps, but it seems like you have the idea.
What is it you mean by "it isn't a normal procedure"? Sure, one would
normally add a disk then remove a disk but if you don't need the space,
why bother?
CAVEAT: have a complete backup of the data off the box on which the LVM
system is managed.
Good luck.
Doug.
