Hi there, I'm currently trying to restore a core from a snapshot, and it does not work as excepted (in my case).
My context: I'm using solr 5.3.0 i used named snapshot and specific location to ensure collection integrity a a time in a single directory below, i will describe backup/restore for a specific core backup command: http://10.0.2.15:8080/solr/test_shard2_replica1/replication?wt=json&command=backup&location=%2Fhome%2Fsolr%2Ftest%2F20151128-073603009560&name=test_shard2_replica1 it has created the snapshot with all data: [vagrant@centos7 solr-5.3.0]$ ls -lh /home/solr/test/20151128-073603009560/snapshot.test_shard1_replica2/ total 32K -rw-r--r-- 1 solr solr 346 Nov 28 07:36 _5.fdt -rw-r--r-- 1 solr solr 84 Nov 28 07:36 _5.fdx -rw-r--r-- 1 solr solr 431 Nov 28 07:36 _5.fnm -rw-r--r-- 1 solr solr 110 Nov 28 07:36 _5_Lucene50_0.doc -rw-r--r-- 1 solr solr 697 Nov 28 07:36 _5_Lucene50_0.tim -rw-r--r-- 1 solr solr 171 Nov 28 07:36 _5_Lucene50_0.tip -rw-r--r-- 1 solr solr 432 Nov 28 07:36 _5.si -rw-r--r-- 1 solr solr 165 Nov 28 07:36 segments_7 i flush all data from the same core and restart the solr5 instance and then try to restore from the previous snapshot: [vagrant@centos7 solr-5.3.0]$ curl "http://10.20.1.16:8082/solr/test_shard1_replica2/replication?wt=json&command=restore&location=%2Fhome%2Fsolr%2Ftest%2F20151128-073603009560&name=test_shard1_replica2"; {"responseHeader":{"status":0,"QTime":53},"status":"OK"} all seems to be OK, let's verify [vagrant@centos7 solr-5.3.0]$ curl "http://10.20.1.16:8082/solr/test_shard1_replica2/replication?wt=json&command=restorestatus"{"responseHeader":{"status":0,"QTime":2},"restorestatus":{"snapshotName":"snapshot.test_shard1_replica2","status":"success"}} great!! what about logs: [...skipped data...] 2015-11-28 07:42:39.128 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5.fdt to restore directory 2015-11-28 07:42:39.129 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5_Lucene50_0.tip to restor e directory 2015-11-28 07:42:39.129 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5.si to restore directory 2015-11-28 07:42:39.130 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5_Lucene50_0.doc to restor e directory 2015-11-28 07:42:39.132 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5_Lucene50_0.tim to restor e directory 2015-11-28 07:42:39.134 INFO (restoreExecutor-8-thread-1-processing-x:test_shard1_replica2 r:core_node4 test_shard1_replica2 n:10.20.1.16:8082_solr snapshot.test_shard1_replic a2 s:shard1 c:test //home//solr//test//20151128-073603009560) [c:test s:shard1 r:core_node4 x:test_shard1_replica2] o.a.s.h.RestoreCore Copying file _5.fdx to restore directory [...skipped data...] Wow , i love solr ;) now, let's have a look at data directory: [vagrant@centos7 solr-5.3.0]$ ls -lh /usr/local/third/solr-5.3.0/server/solr/test_shard1_replica2/data/* -rw-r--r-- 1 solr solr 92 Nov 28 07:42 /usr/local/third/solr-5.3.0/server/solr/test_shard1_replica2/data/index.properties /usr/local/third/solr-5.3.0/server/solr/test_shard1_replica2/data/restore.snapshot.test_shard1_replica2: total 0 -rw-r--r-- 1 solr solr 0 Nov 28 07:42 write.lock /usr/local/third/solr-5.3.0/server/solr/test_shard1_replica2/data/tlog: total 0 Hum, no data, what did i miss? in order to workaround, i can restore from filesystem, but this behavior is making me mad :) thanks for your help ;)
