Subject SOLR cloud creating multiple copies of the same index
Date Fri, 25 Jul 2014 20:50:50 GMT
Hi , we have a solr cloud instance with 8 nodes and 4 shards. We are starting
to see that index size is growing so huge and when looked at the file system
solr has created several copies of the index.
However using solr admin, I could see its using only on the them.

This is what I see in solr admin.

Index:
    /opt/solr/collections/aq-collection/data/index.20140725024044234

Master (Searching) 	
1406320016969
	
Gen - 81553
	
size -58.72 GB.

But when I go in to the file system , This is how it looks.

16G   index.20140527220456134
  45G   index.20140630001131038
 4.6G   index.20140630090031282
  20G   index.20140703192128959
 1.3G   index.20140703200948410
  31G   index.20140708162308859
  52G   index.20140716165801658
  59G   index.20140725024044234
   4K   index.properties
   4K   replication.properties

it is actually pointing only to the index.20140725024044234, and using that
for searching and indexing. The timstamps on other indexes are old(about a
month or so)

Can some one explain me why it created so many copies of the index(we did
not create them manually). and how it can be prevented.

Our solr instances are running on solaris VMs
