Build output lost after upgrade to 8.3
After upgrading to 8.3 the build output for all our CI builds has disappeared.
This happened before when upgrading to 8.0, see issue #2647 (closed)
However, we are unable to restore the build logs using the same methods. The builds folder is owned by git:git
The actual log files are present in the builds folder. One odd thing is the filename is 1 less than the build id it corresponds to. So for example build 2059 is logged at /var/opt/gitlab/gitlab-ci/builds/2015_12/15/2058.log
