lvmetad is part of lvm2 source base spread in couple places:
Usually it's best to attach to running lvmetad and explore it in gdb
Also be sure you run with latest version - fixing bug in a year old code is
not usually helpful.
It's also good if you could prepare a reproducer case (so it could be placed
in test suite)
