As like many time before, as soon as Isent the e-mail with a question, a
lightbulb went off in my mind.
1. Unmount filesystem (I only have one in the group) on Logical Volume.
2. Resize Logical Volume since I stretched it before (did not know how
all that goes). I resized it to well over the size of sdd7. I used LVM
GUI for filesystem+LV resize in one go.
Now:
3. pvmove to move away all allocated extents
4. vgreduce
I hope those last too go without a problem. Will report back.
