MarsSeed [1] filed a deletion request for pacemaker1.1 [2]: Boken, abandoned pkg from 2020. Fails checksum verification. But also cannot be built due to incompatibility with dependency libesmtp. I don't think it's useful to keep this EOL version from 2020. AUR has a working package for the current release (AUR/pacemaker).
