Description

Per the description. We will expect it to be an identical format we just want to be able to over-ride http://gitbuilder.ceph.com/ with an alternative URL that is expected to mirror that (or atleast be in the same format).

Should be a fairly minor code change.

Buried in teuthology.task.install I found:
https://github.com/ceph/teuthology/blob/master/teuthology/task/install.py#L257

If we could generalize that (and make it use teuthology.config instead), that would get us pretty far. Clearly there are several other modules that would need modification though.

Unfortunately, I am currently seeing a ton of this:

So... we might want to fix the mirror.

That probably happened due to files still being copied. I think the problem is that the symbolic link in ref/ is being updated even when files are still being copied. I will try to think of a good way around this.

That seems like a problem that has to have been solved. What do other people running package repo mirrors do?

The complication is there are two parts to this.. There is the actual repos being copied and then there is the symlink that is in /ref that points to the actual folder in the sha1 folder. The problem is there isn't a very nice way to copy the links after based on destination of link.

It should be fixable I think I am just going to have to run a readlink loop on all the links in /ref on the destination gitbuilder and only copy over ones that match the same destination as the sha1 that was just copied (after the sha1 is done syncing). It would be nice if there was an rsync option that would get me this kind of behavior but I seriously doubt that will be the case. A lot of the complication is coming from the fact that we only have one way access to the gitbuilder-archive. Things would be much simpler if the gitbuilders could simply rsync to another mirror but unfortunately for security reasons we can't do that :(

I will work out a solution today.

I believe this should be fixed now. After syncing the sha1 it checks the remote gitbuilder archive server its mirroring from to see if any of the /ref symlinks point to its sha1 and syncs those refs instead of blindly syincing all of the /ref's like it used to. The problem is that often times we have multiple syncs even going from the same gitbuilder due to the network slowness which was causing the /ref to get updated earlier. For example earlier today I saw all these parallell sync's going on:
