How to fix Sonatype Nexus OrientDB "component" database?

[Carlo Reggiani]

Hi

Maybe after a "low disk" situation (we added some disk space to sonatype-work filesystem) we are getting errors related to maven operation.

In the log we are getting a loto of:

"2017-12-13 00:06:12,866+0100 ERROR [quartz-1-thread-5] *SYSTEM com.orientechnologies.orient.core.storage.impl.local.paginated.OLocalPaginatedStorage - $ANSI{green {db=component}} Exception `754BDA32` in storage `component`

    at com.orientechnologies.orient.core.serialization.serializer.binary.impl.index.OCompositeKeySerializer.deserializeFromByteBufferObject(OCompositeKeySerializer.java:46)
    at (...)"

Reading on https://issues.sonatype.org/browse/NEXUS-14174 I tryed to connect to the local db from console, but I'm getting error! Any idea how to fix?

This doesn't look like something you can fix, it's saying the component database is entirely missing:

Cannot open the storage 'component' because it does not exist in path: /opt/sonatype/sonatype-work/nexus3/db/component

What exactly happened here? I don't see how a full disk can cause the component database to disappear. 

Have you been taking backups?  If so, you can use those to restore:

Hi Rich

I'm looking for the first time a OrientDB database: /opt/sonatype/sonatype-work/nexus3/db/component is a folder with a lot of files.

In this folder, related to "component" there are this files:

Which is the "missing" file?

Thanks for any support :(
