Re: SolrCore Initialization Failures
Thanks for your response. None of the processes are deleting any index files. One data directory is only pointed by one core. We are writing data at a high ingestion rate (100,000 records per second). Commit happens once every 30 seconds. Also a periodic service runs to backup the data to our backup data store. This service starts by saving commit point & when its done, it released the commit point. Could this combination of these factors some how cause the deletion of files? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html

SolrCore Initialization Failures
Hi, I am using solr 7.2.1 Every now & then some of the cores fail to load due to "SolrCore Initialization Failure". >From error message it looks like the reason for failure is the core missing some of the files: org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Error opening new searcher Caused by: java.nio.file.NoSuchFileException: /opt/solr/volumes/data1/xxx-core-5/index/_xxx.cfe But I could not find any reason for the loss of these files. Also downloading the missing files from the backup we maintain resolves this issue. Any idea what might be causing this? Thanks -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
Determining replication status
I am trying to copy contents of one core to other core by using fetchIndex command (/solr/CORE_NAME/replication?command=fetchindex&masterUrl=MASTER_URL). How can I determine if the copy is actually complete? I am using replication details command (/solr/CORE_NAME/replication?command=details) to check. I use isReplicating field & if its false, I consider the operation to be complete. But this approach is not giving me accurate results some time. -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
CoreDescriptor not found in CoreCache
I am using solr 6.6.2. In case of an init failure in core, CoreDescriptor of such a core is not present in the core cache (TransientSolrCoreCacheDefault). Is this behavior expected? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
