Hello,
We are using Solr 9.7.0 in User-Managed Mode with one node acting as Leader (write only) where we perform indexing and two nodes as followers (read only) which replicates from Leader. We run delta through out the day to keep the core on Leader updated but we run a full indexing job overnight which will index in a "cold" core on the Leader and once the indexing is finished on the cold core, we use SWAP<https://solr.apache.org/guide/solr/latest/configuration-guide/coreadmin-api.html#swap-parameters> to switch the hot and cold cores. We don't see any issue in the Leader node but follower nodes keeps the copy of the previous indexes and thus filling the disk space. If we reload the core on the secondary or restart solr service, the space frees up and old index files get deleted. We tried playing around with the "deletionPolicy" in solrconfig.xml but it did not help. We had SOLR 7 running before and did not see this issue there. Has anyone else ran into this issue before or can give us any recommendations? Thanks, Varun
