Description

There is an error in the alignment of dataminer service in the proto cluster.
Above all, the dataminer0-proto and dataminer4-proto are not aligned correctly. It could also be a problem of concurrent access to svn.

I've found the problem. Working on the fix, then I'll explain what was happening.

Two events occurred:

  1. Sometimes the svn update fails because of a write lock on the svn repository. This means that someone is running a commit on the repository and there's nothing that we can do on our side (we do not want doing anything, really). When the svn update fails, the script exits without releasing its own lock file. Not a big deal, but:
  2. The check that verifies that no other instance of the script is running failed in some situations. It was the case on dataminer0-proto and dataminer4-proto.

I just made that check more robust and installed it on all the production dataminer

Now, it seems that it works correctly. I close the ticket.
