Reindex issue with gerrit 3.9.1 after copying the repos from another server

[Sweta Asnodkar]

Hello Team,

I setup gerrit new server. I copied the repos from our production server. When I try to start gerrit, it gives me below error

[wnc-0]] WARN  com.google.gerrit.server.index.change.AllChangesIndexer : Failed to read change 799 for indexing
com.google.gerrit.server.notedb.InvalidServerIdException: invalid server id, expected 9d6291cb-c956-429a-be2a-f18a07a5f4ae: actual: da954faa-1105-40b5-9aee-3e1b1ec9f210

It is expecting the server id of production sever from where I have copied the repos.

Id there any work around for this?

If I copy the same server id as production server on the new gerrit, will it affect the production server? I don't want to harm the production server.

Thanks,

Sweta

I believe this more-or-less a safety feature so that you can control which gerrit servers you should import changes and change-metadata from.
The server-id is part of the author of the Note DB commits:
```
commit cfc49e826887b3b8a4a4a733315ad4fdc99f2d1d
Author: Gerrit User $USER_ID <$USER_ID@$SERVER_ID>
Date:   Wed Jun 12 11:21:20 2019 +0000
```

By adding the server id from production as an Imported server id (https://gerrit-review.googlesource.com/Documentation/config-gerrit.html#gerrit.importedServerId) in the configuration of your staging instance you acknowledge that the staging server should accept changes and change-metadata created by the production server(s).

The only way it might become an issue is if you add the staging-server's server-id as importedServerId in production as that opens up an opportunity for making mistakes.

Thank you Sven for your reply.

>> I added the property as you mentioned, and reindexing worked and gerrit came up too.

Just one issue:

          Changes which I open now, for Owner it is said "Name of user not set"

           Also the changes created by this user is not visible. 

Is it because the author details are associated with the server id?

Thanks,

Sweta

Account information is stored in the All-Users repository. This means when transferring changes from another server

you also need to import the respective account information used in those changes otherwise their data is unknown

to the server where you imported changes.

Sorry for spam, but can someone please help me here? I am stuck at one point to find out how do I import the account information to another server.

Have you done an offline reindex of accounts after you copied All-Projects?

`GERRIT_SITE$ java -jar bin/gerrit.war reindex --index accounts`

https://gerrit-review.googlesource.com/Documentation/pgm-reindex.html

[Sweta Asnodkar]

Hi Sven,

Yes I did run  java -jar bin/gerrit.war reindex --index accounts. Reindexed 601 accounts but still not showing the owners name (Shows Name of user not set as attached in the screenshot) in the change

Collecting accounts:    601
Reindexing accounts:    100% (601/601)
Reindexed 601 documents in accounts index in 0.6s (933.2/s)

Thanks

Sweta

If you know the email address of the account you can try to search it to find out if it's present in All-Users.
E.g. from a gerrit test site:

All-Users.git (BARE:refs/meta/config)]$ git grep user_1 refs/meta/external-ids
refs/meta/external-ids:73bc819d6010850ce903d05f6c8e4ddee8675ca0:        email = use...@example.com

All-Users.git (BARE:refs/meta/config)]$ git show refs/meta/external-ids:73bc819d6010850ce903d05f6c8e4ddee8675ca0
[externalId "gerrit:user1"]
        accountId = 1000002
        email = use...@example.com

All-Users.git (BARE:refs/meta/config)]$ git show refs/users/02/1000002:account.config
[account]
        preferredEmail = use...@example.com
        fullName = User One
        displayName = one

 

Thanks

Hi Mathias,

I am able to search for the users using above commands. But problem is  the display information related to the users and the changes associated with that user.

When I open a change and click on the user there are no associated changes which are displayed. 

I am kind of stuck as I have to also implement the OWNERs plugin for the same. Unless I get the user information, owners plugin won't work for assigning reviewers.
