Add a document Do you call commit after that? > Restore functionality not working > --------------------------------- > > Key: SOLR-8449 > URL: https://issues.apache.org/jira/browse/SOLR-8449 > Project: Solr > Issue Type: Bug > Components: replication (java), replication (scripts) > Affects Versions: 5.2.1, 5.4 > Environment: SUSE Linux Enterprise Server 11 (64 bit) and Windows 7 > Prof SP1 > Reporter: Johannes Brucher > Priority: Critical > Attachments: log_windows7_sp1.txt > > > Hi all, I facing the following issue with Solr 5.2.1 and the ongoing version > 5.4. > The restore functionality is not working under Linux and causing an exception > on Windows machines each time you want to restore an existing backup twice or > even more. > Steps to reproduce: > 1. Start a Solr instance pointing the solr_home to e.g. the example-DIH > folder. > 2. Select a core, e.g. the “solr” core. > 3. Switch to the “Documents” tab > 4. Add a document {“id”:”1”,”title”:”change.me”} > 5. Do a backup with the following API call > “/solr/replication?command=backup&name=test” > The backup defaults to the location solr_home/solr/data/snapshot.test > 6. Add a document to the index {“id”:”2”,”title”:”change.me”}. Now there a > two document in the index. > 7. Restore the back with the following call > “/solr/replication?command=restore&name=test” > New index location “solr_home/solr/data/restore.snapshot.test” is created > without any physical file in it, except the file write.lock. Num Docs is now > 1 as expected! > 8. Add a document to the index {“id”:”3”,”title”:”change.me”}. Now there a > two document in the index. > 9. Restore the same previous created back again with the following call > “/solr/replication?command=restore&name=test”. Notice, there are still 2 docs > in the index!!! > 10. Try to restore again, but still the same, 2 docs in the index… > 11. Shut down Solr, you will see the index folder > “solr_home/solr/data/restore.snapshot.test” disappears. > 12. Restart Solr. You will notice the following log entry “Solr index > directory ‘solr_home/solr/data/restore.snapshot.test’ doesn’t exist. Creating > new index”, and indeed the Index is empty, showing 0 documents. > 13. After the restart, I tried to restore the existing backup again without > any results… > I thing this behavior in not intended!!! > Even more Problems arise when you run Solr on a Windows machine. > After step 10 a folder “index” is created under “solr_home/solr/data/” with a > write.lock file in it. After that, the following exception is thrown: > …Error closing IndexWriter > java.lang.IllegalStateException: file: > MMapDirectory@D:\solr\Solr_versions\solr-5.2.1\...restore.snapshot.test > lockFactory=org.apache.lucene.store.Nat > iveFSLockFactory@3d3d7a0e appears both in delegate and in cache > The log file from the Windows test is attached. > Let me know if you have problems reproducing the same behavior, > Regards Johannes -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
