The newest Nexus version 3.74 offers via API the read-only mode, but as the description suggests just for the old OrientDB.

Ist it possible to set a Nexus repo instance completely to **read only**?  
Background is, that our H2 database corrupts now all the time and we want to at least set it to read-only mode if that is achievable.

There isn’t a read-only mode for H2 at the moment. Are you looking to prevent further corruption while you debug, is that why you want a read-only mode?

Yes, if possible we want to the user to be able to pull.

The database corruption started around 3 weeks ago and until now we cannot prevent the database being corrupted after some hours of Nexus running.

A new instance is set up in parallel.
