Our index size is 110GB and growing, crossed RAM capacity of 96GB, and we are seeing a lot of disk and network IO resulting in huge latencies and instability(one of the server used to shutdown and stay in recovery mode when restarted). Our admin added swap space and that seemed to have mitigated the issue.
But what is the usual practice in such scenario? Index size eventually outgrows RAM and is pushed on to disk. Is it advisable to shard(solr forum says no)? Or is there a different mechanism? System config: We have 3 node cluster with RAID1 SSD. Two nodes are running solr and the other is to maintain Quorum. -E
