I’m having a hard time to get 2 machine cluster synchronised. Log is full of rows similar to:
W20211012 12:47:32.217510 27509 node.cpp:2308] node default_group:10.6.5.21:8107:8108 reject term_unmatched AppendEntries from 10.6.5.20:8107:8108 in term 20 prev_log_index 20 prev_log_term 5 local_prev_log_term 3 last_log_index 16195 entries_size 0 from_append_entries_cache: 0

Any idea what causes this?

👋 Clustering requires minimum 3 nodes for quorum.
