but I still worry a bit about my data. The reason for the wrong "Free 
PE"
reported seems not to be the 64k limit, but the fact that some of my LVs
are reported/counted twice!

-> vgdisplay -v vg0  | fgrep "LV Name"
LV Name                /dev/vg0/root
LV Name                /dev/vg0/win2k
LV Name                /dev/vg0/ortho
LV Name                /dev/vg0/praktikum
LV Name                /dev/vg0/swap
LV Name                /dev/vg0/mirror
LV Name                /dev/vg0/disk_huetti
LV Name                /dev/vg0/SuSE-7.3
LV Name                /dev/vg0/mirror          <<<<<
LV Name                /dev/vg0/disk_huetti     <<<<<

Thus I still fear of some evil inconsistencies for my data.
Is there any tool available like "e2fsck" for LVM to resolve such a
problem?

Dieter.
