i have a setup with two solr indices containing records for a vufind
instance.
the leader acts as harvester and collects records/documents from various
sources.
the follower just replicates the leader and serves as index for our
search engine.
this setup seemed to have worked very stable for several years, but
since we updated our vufind instances - hence our solr instances, we are
getting a strange behavour:
about weekly the follower seems to overtake the leader somehow. just
today i found the leader empty and claiming being one generation ahead
of the leader.
i do not understand how this happens.
the only workaround to fix this i found so far is deleting the follower
index from the harddrive and restart solr. the follower then has gen 1
again and feels ready to replicate.
i added a screenshot of the replication status page of the follower in
the state of refusing replication and having zero documents.
in the mail from 04/02/2025, 11:32 i sent you parts of my
solr/vufind/biblio/conf/solrconfig.xml of leader and follower.
