When I create an lvmthinpool with size S and poolmetadatasize P, it reduces the available freespace by S+2P. I expected that to be S+P. Where did the extra poolmetadatasize get used? See below for example. before lvcreate we had 255868 free, after we had 254588. The difference is 1280. (1024 + 2*128).
lvm2 preallocated hidden _pmspare volume which has the size of biggest metadata LV in a VG. Such LV is used for automated 'lvconvert --repair'. If you don't want this LV to be created you can add --poolmetadataspare y|n but in this case you are fully in your own to figure out, where to take the space for repaired metadata. You can also at any time lvremove _pmspare LV if necessary.
