I used a GUI for this not the CLI, first I tried to move the extents to other PVs (which I think is that pvmove does) and then to actually remove it from the group (which is probably what vgreduce does). If I am not mistaken, the first operation gave an error even though it appeared to have worked somehow at the time.

it seems to be some leftover from the pvmove operation, unfortunately i
have no idea if some data was not actually moved correctly.
did you record the error message the pvmove operation reported?
