And your config is?
And you logs say?

As is, I can only take an (educated) wild guess:

Do you have no (or improperly configured) fencing,
and funky auto-resolve policies configured,
after-split-brain ... discard-secondary maybe?

Configuring automatic after-split-brain recovery policies
is configuring automatic data loss.

So if you don't mean that, don't do it.
