Hello, My question is if there is any way to backup a Solr cluster even when all replicas are "not synced"...
I'm using the api to create the dumps: http://localhost:8983/solr/admin/collections?action=BACKUP&name=myBackupName&collection=myCollectionName&location=/path/to/my/shared/drive But is a lottery where the most of time a collection fails and is impossible to backup until you restart the node that looks out of sync. Error: { "responseHeader":{ "status":500, "QTime":4057}, "failure":{ "192.168.3.14:8983_solr":"org.apache.solr.client.solrj.impl.HttpSolrClient$RemoteSolrException:Error from server at http://192.168.3.14:8983/solr: Failed to backup core=myproducts_shard1_replica_n91 because java.nio.file.NoSuchFileException: /server/solr/solr-data/data/myproducts_shard1_replica_n91/data/index.20180212231626422/segments_5kjp"}, "Operation backup caused exception:":"org.apache.solr.common.SolrException:org.apache.solr.common.SolrException: Could not backup all replicas", "exception":{ "msg":"Could not backup all replicas", "rspCode":500}, "error":{ "metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"Could not backup all replicas", "trace":"org.apache.solr.common.SolrException: Could not backup all replicas\n\tat org.apache.solr.handler.admin.CollectionsHandler.handleResponse(CollectionsHandler.java:306)\n\tat org.apache.solr.handler.admin.CollectionsHandler.invokeAction(CollectionsHandler.java:243)\n\tat org.apache.solr.handler.admin.CollectionsHandler.handleRequestBody(CollectionsHandler.java:221)\n\tat org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandlerBase.java:177)\n\tat org.apache.solr.servlet.HttpSolrCall.handleAdmin(HttpSolrCall.java:745)\n\tat org.apache.solr.servlet.HttpSolrCall.handleAdminRequest(HttpSolrCall.java:726)\n\tat org.apache.solr.servlet.HttpSolrCall.call(HttpSolrCall.java:507)\n\tat org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:382)\n\tat org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilter.java:326)\n\tat org.eclipse.jetty.servlet.ServletHandler$CachedChain.doFilter(ServletHandler.java:1751)\n\tat org.eclipse.jetty.servlet.ServletHandler.doHandle(ServletHandler.java:582)\n\tat org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:143)\n\tat org.eclipse.jetty.security.SecurityHandler.handle(SecurityHandler.java:548)\n\tat org.eclipse.jetty.server.session.SessionHandler.doHandle(SessionHandler.java:226)\n\tat org.eclipse.jetty.server.handler.ContextHandler.doHandle(ContextHandler.java:1180)\n\tat org.eclipse.jetty.servlet.ServletHandler.doScope(ServletHandler.java:512)\n\tat org.eclipse.jetty.server.session.SessionHandler.doScope(SessionHandler.java:185)\n\tat org.eclipse.jetty.server.handler.ContextHandler.doScope(ContextHandler.java:1112)\n\tat org.eclipse.jetty.server.handler.ScopedHandler.handle(ScopedHandler.java:141)\n\tat org.eclipse.jetty.server.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:213)\n\tat org.eclipse.jetty.server.handler.HandlerCollection.handle(HandlerCollection.java:119)\n\tat org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134)\n\tat org.eclipse.jetty.rewrite.handler.RewriteHandler.handle(RewriteHandler.java:335)\n\tat org.eclipse.jetty.server.handler.HandlerWrapper.handle(HandlerWrapper.java:134)\n\tat org.eclipse.jetty.server.Server.handle(Server.java:534)\n\tat org.eclipse.jetty.server.HttpChannel.handle(HttpChannel.java:320)\n\tat org.eclipse.jetty.server.HttpConnection.onFillable(HttpConnection.java:251)\n\tat org.eclipse.jetty.io.AbstractConnection$ReadCallback.succeeded(AbstractConnection.java:283)\n\tat org.eclipse.jetty.io.FillInterest.fillable(FillInterest.java:108)\n\tat org.eclipse.jetty.io.SelectChannelEndPoint$2.run(SelectChannelEndPoint.java:93)\n\tat org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.executeProduceConsume(ExecuteProduceConsume.java:303)\n\tat org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.produceConsume(ExecuteProduceConsume.java:148)\n\tat org.eclipse.jetty.util.thread.strategy.ExecuteProduceConsume.run(ExecuteProduceConsume.java:136)\n\tat org.eclipse.jetty.util.thread.QueuedThreadPool.runJob(QueuedThreadPool.java:671)\n\tat org.eclipse.jetty.util.thread.QueuedThreadPool$2.run(QueuedThreadPool.java:589)\n\tat java.lang.Thread.run(Thread.java:748)\n", "code":500}} After restart the node that give the error then is able to dump the backup without my problem, but i can't restart all nodes that fail and every day to dump the data. is there any way to do it?
