Ok, i have found the right button:
after creation of the new lv my problem as described:
[root at xen02 ~]# lvcreate -L 200G -n webint01_xvdb vg_data2
Error locking on node xen02.tilak.ibk: Volume group for uuid not
found: wP3rMbP704LoUcUawH8eMq77AyRPJ5in43a93ifh0KYJ1HfD77UPFXF52wwrLrEs
Error locking on node xen03.tilak.ibk: Volume group for uuid not
found: wP3rMbP704LoUcUawH8eMq77AyRPJ5in43a93ifh0KYJ1HfD77UPFXF52wwrLrEs
Error locking on node xen01.tilak.ibk: Volume group for uuid not
found: wP3rMbP704LoUcUawH8eMq77AyRPJ5in43a93ifh0KYJ1HfD77UPFXF52wwrLrEs
Failed to activate new LV.
and then
restart service clvmd
-> the lv is active ...
done on all nodes, xen doesnt matter, everything online
