Hi list, we have a Solr Cloud setup with a collection with 4 shards. We backup this collection once a day.
Each night, we try to restore the latest backup on a test server. So we restore all shards to the same machine. Upon restore, the solr logs prints the following: solr.log.3:25163:java.nio.file.NoSuchFileException: /tmp/solr_restore_2019-06-30T21_47_53_380/solr.procurement_full.snapshot_tmp/snapshot.shard3/_hx_Lucene50_0.tim solr.log.3:25190:java.nio.file.NoSuchFileException: /tmp/solr_restore_2019-06-30T21_47_53_380/solr.procurement_full.snapshot_tmp/snapshot.shard4/_wc_Lucene50_0.tim When Solr has loaded, these two shards are empty. Looking at the cores, shard3 and shard4 has index directory set to the generic data/index. e.g /var/solr/data/procurement_shard3_replica_n3/data/index whereas shard1 and shard2 correctly points to data/restore.xxxxxxx, e.g. /var/solr/data/procurement_shard1_replica_n7/data/restore.20190701015508919 We monitor the restore process by polling http://localhost:8983/solr/admin/collections?action=REQUESTSTATUS&requestid=procurement_restore The restore action never enters a failed, and the last state is "completed": { "responseHeader":{ "status":0, "QTime":540}, "status":{ "state":"completed", "msg":"found [procurement_restore] in completed tasks"}} It might well be that there is some error in the backup that we are trying to restore (although backup finishes without error), which is causing this problem, but I would expect the restore processs to end up in a failed state, instead of a state with two functional shards and two empty. Can anybody help me out here? Thanks, /Bjarke
