Hour hint to the tmvthin-manpage was right:

lvextend -L+96M dmivg/winthinpool_tmeta

worked!

Now Metadata is safe:

  --- Logical volume ---
  LV Name                winthinpool
  VG Name                dmivg
  LV UUID                gDGkhM-jGQq-hSuZ-g4CZ-JtcQ-JcdX-DqD7bi
  LV Write Access        read/write
  LV Creation host, time dmicn20, 2014-10-07 23:54:45 +0200
  LV Pool metadata       winthinpool_tmeta
  LV Pool data           winthinpool_tdata
  LV Status              available
  # open                 73
  LV Size                930,00 GiB
  Allocated pool data    50,85%
  Allocated metadata     45,91%
  Current LE             238080
  Segments               1
  Allocation             inherit
  Read ahead sectors     auto
  - currently set to     256
  Block device           252:18


Tfh!
