Hi All,

We have recently upgraded our Gerrit setup to 3.5.6 from 3.2.14. 
We have a HA setup with the help of High Availability plugin. We do not use external refDB.

We were particularly caught off guard with a requirement of a lib during the upgrade process and thought we will request the community to make a point to update the documentation.

We upgrade our Gerrit installation to 3.5.6 and try to start the service. It refuses to come up with the below stack trace.
We got a pointer [1] from an earlier repo discussion about the requirement of a lib. We downloaded the particular lib [2] into our site's /lib directory and the Gerrit started working fine.

I would here by request to add a point in the release notes about this requirement.

You’re missing the global-refdb.jar into the $GERRIT_SITE/lib.

Hi Luca,

Yes we found that and used it. My request is to add that info that we need to have that lib in the Gerrit release notes so that everyone knows about it beforehand.

Regards,
Raviraj

The global-refdb isn’t part of Gerrit core therefore isn’t included in the release notes.
The release notes are already a colossal effort, including all the details of all plugins won’t be feasible.

I think this should be added to the documentation of the high-availability plugin.

The active/active configuraiton is already mentioned at [3].
I am sure it can be improved with Matthias’ contribution :-)

I misread your e-mail: I don’t believe the global-refdb should have been required as *you do not use it*.
I believe this is a bug and should be fixed in the high-availability plugin.
