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.
