Thanks for the feedback on this issue. I've setup 15 to 20 servers in the past 6 months and never had any problems. I can see how hardware errors may be the problem but would expect to see lower level messages like would happen with Java. Will tell the client that this might be a problem.
For this particular case there will be a fresh install of MarkLogic version 5.

This could be due to a filesystem bug, but that is very rare. More likely it is a failing disk or a bad cable. So I would make an effort to track that down and resolve it before proceeding. The next step is to update the license key. Until you have done that, the server won't allow any updates. The NetVisn_EFBIProd has probably lost data. Those XDMP-READ errors in TreeData mean that some fragments won't be recoverable. But if the filesystem corruption isn't too bad, a forced reindex might recover some of the data. Again, I would not try that until the underlying storage problem has been fixed, and the filesystem has been repaired. At that point if reindexing doesn't sound attractive and you would rather start over, you could clear that forest in the admin UI. That will delete all the suspect forest data, without touching the server configuration. Deleting F:\Program Files\MarkLogic\Data is more drastic, and will also delete the server configuration. If you do that, be sure that you have a backup copy of any configuration data you want, and the new license key. -- Mike On 7 May 2012, at 12:09 , Geert Josten wrote: > Hi Gary, > > If you have support, you can contact [email protected] to discuss best solution for the corrupt index files. Personally, doesn't sound like expiration of your license was the case of the problems. You are talking about restoring the database, do you actually mean from backups? In that case, it may differ with which version it was made, including win vs. unix, 32 vs. 64bit.

If you just delete the data, which is an option, then upgrade to the latest of v4.2 first, to make sure all things like app services and such get migrated correctly to v5. > > Kind regards, > Geert > > Van: [email protected] [mailto:[email protected]] Namens Gary Larsen > Verzonden: maandag 7 mei 2012 18:48 > Aan: 'MarkLogic Developer Discussion' > Onderwerp: [MarkLogic Dev General] Log errors > > The MarkLogic log files are huge and contain mostly errors. I'm wonder if there is any hope of restoring this database on v4.2 without having a backup available.
