Hi. We run a solr 9.10.0 cluster on Azure kubernetes. The 15 node cluster has been created by using the solr operator 0.9.1. The cluster contains 42 collections, ranging from small (only a few thousand documents , to biggest, containing 130 million records) Each collection has 1 or more shards , with one or more replica's
We run a full import of all data every day. After a new full import has been completed, we update the alias , and reload the old collection to free up the cache. We see sometimes errors like these: index-20260204-0345_shard12_replica_t77: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Index dir '/var/solr/data/index-20260204-0345_shard12_replica_t77/data/index.20260205061901006' of core 'index-20260204-0345_shard12_replica_t77' is already locked. The most likely cause is another Solr server (or another solr core in this server) also configured to use this directory; other possible causes may be specific to lockType: native The weird thing is this is the collection for the "old" reloaded collection. Does anyone have any ideas?
