</blockquote></div><br><div>Does this mean it is in the works? If not, where could I put in such feature request?</div><div><br></div><div>Certainly, I have no pressing need of this, but it seems like a fairly simple thing to implement since I have done it so easily in the past with a just a couple of commands outside of an oVirt environment. I believe the primary purpose of the LVM functionality was to enable removal of dying PVs before they take out an entire VG. No reason it would not work just as well to remove a healthy PV. It can take a long time to move all the extents off the PV requested, but there is command to show the progress, so it would also be easy to wrap that in to the GUI.</div>
