Excerpts from corvus's message of 2017-09-20 15:23:21 -0700: > Hi, > > We originally created the docs-draft site (and filesystem partition) > because doc builds were *big* and we had to expire them much more > quickly than build logs. The expiration times were 21 days for > docs-draft and 6 months for build logs. > > The tables have turned. > > Docs-draft expiration is still 21 days, but build logs have gotten so > large we've reduced expiration there to 30 days. > > Since they are more closely matched now, we can fold docs-draft back > into the logs volume and gain several benefits. We're currently using > 299G of space for docs-draft. Accounting for the extra 9 days of > retention would bring us to about 427G of space. Our current headroom > on logs is 3.0T, so we can handle that change immediately with no ill > effect. > > Once the existing retention period has expired, we can reclaim the space > from the doc-draft volume and gain an additional 1.5T of capacity in > logs. Once that is done, accounting for the increased use from > docs-draft jobs, we'll have an overall net gain of 1T of free space. > > On top of all that, we will improve the UX of the docs-draft system by > making it easier to switch to the build logs on a successful build. > Currently we have to edit the hostname in the URL to do so; but in the > future, we can simply remove trailing path components. > > Assuming there aren't any objections, we can effect this change during > the v3 transition, then perform the volume reclamation 3 weeks later. > > -Jim >
