607748 - make mirror saturation take less time

Status: RESOLVED FIXED

(Release Engineering :: General, defect, P4)

Description

[[e-mail] (:bhearsum)]

There's lots of different ways we could make mirror saturation faster, and we should do it. Some ideas:
- Do candidates directory -> releases rsync directly on dm-ftp01, instead of over an NFS mount
- Stage releases directory somewhere hidden/inaccessible ahead of time, and move it to the final location when we "go to mirrors"
- Pre-populate the mirrors with hidden/inaccessible files, and flip them on when we "go to mirrors" (this would depend on stricter mirror configuration requirements)

IT recently made a change that allows us to push out to Mozilla mirrors well in advance of a release. We haven't used it yet, but depending on how it goes we may not care to do anything more here.

I think we've done enough to call this FIXED. We always pre-seed the internal mirrors these days, and with 9.0.1, we managed to get good uptake on the full network in about 2 hours.
