When reimaging the Gerrit replica on gerrit2002 (T334521) the daemon refused to start:
[2023-05-25T16:43:09.408Z] [main] ERROR com.google.gerrit.pgm.Daemon : Unable to start daemon com.google.inject.ProvisionException: Unable to provision, see the following errors: 1) No index versions for index 'groups' ready; run java -jar /var/lib/gerrit2/review_site/bin/gerrit.war reindex --index groups 1 error at com.google.gerrit.server.index.VersionManager.initIndex(VersionManager.java:172) at com.google.gerrit.server.index.VersionManager.start(VersionManager.java:95) at com.google.gerrit.lifecycle.LifecycleManager.start(LifecycleManager.java:95) at com.google.gerrit.pgm.Daemon.start(Daemon.java:386) at com.google.gerrit.pgm.Daemon.run(Daemon.java:285) at com.google.gerrit.pgm.util.AbstractProgram.main(AbstractProgram.java:61) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at java.base/jdk.internal.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.base/java.lang.reflect.Method.invoke(Method.java:566) at com.google.gerrit.launcher.GerritLauncher.invokeProgram(GerritLauncher.java:224) at com.google.gerrit.launcher.GerritLauncher.mainImpl(GerritLauncher.java:120) at com.google.gerrit.launcher.GerritLauncher.main(GerritLauncher.java:65) at Main.main(Main.java:28)
I had to:
sudo -u gerrit2 java -jar /var/lib/gerrit2/review_site/bin/gerrit.war reindex --index groups
And I think that created all the necessary indices:
gerrit2002:~$ ls -la /var/lib/gerrit2/review_site/index/ total 28 drwxr-xr-x 6 gerrit2 gerrit2 4096 May 25 16:43 ./ drwxr-xr-x 11 gerrit2 gerrit2 4096 May 25 16:43 ../ drwxr-xr-x 2 gerrit2 gerrit2 4096 May 25 16:43 accounts_0011/ drwxr-xr-x 4 gerrit2 gerrit2 4096 May 25 16:43 changes_0071/ -rw-r--r-- 1 gerrit2 gerrit2 36 May 25 16:43 gerrit_index.config drwxr-xr-x 2 gerrit2 gerrit2 4096 May 25 16:43 groups_0008/ drwxr-xr-x 2 gerrit2 gerrit2 4096 May 25 16:43 projects_0004/
