Since I cannot resync manually using your code and there are not MISSING
flags in /etc/lvm/archive and the different event count for the three
rmetas it seems it would not be helpful, would it?

I diffed the status quo of /etc/lvm/archive with the state before the
troubles and there is no significant difference and there is no difference
in IDs and no MISSING flags.
