While trying to debug an issue with CDCR, I noticed that the /var/solr/data directories on my source cluster have wildly different sizes.
% for i in solr2-{a..e}; do echo -n "$i: "; ssh -A $i du -sh /var/solr/data; done solr2-a: 9.5G /var/solr/data solr2-b: 29G /var/solr/data solr2-c: 6.6G /var/solr/data solr2-d: 9.7G /var/solr/data solr2-e: 19G /var/solr/data The leader is currently "solr2-a" Here's the actual index size: Master (Searching) 1520273178244 # version 73034 # gen 3.66 GB # size When I look inside /var/solr/data/ on solr2-b, I see a bunch of index.* directories: % ls | grep index index.20180223021742634 index.20180223024901983 index.20180223033852960 index.20180223034811193 index.20180223035648403 index.20180223041040318 index.properties On solr2-a, I only see one index directory (index.20180222192820572). Does anyone know why this will happen and how I can clean it up without potentially causing any issues? We're currently on version Solr 7.1.
