[cdwg] Reminder - OpenSFS CDWG call tomorrow, 7/12, at 8:30am Pacific

[Hamilton, Pam]

Hi all,

This is a reminder that we will have a call tomorrow, July 12th, at 8:30am Pacific (Call-in: 866-914-3976 (925-424-8105) Passcode: 534986#).

Agenda:
.	Discuss a process for coming to consensus regarding the next maintenance release

Background:
There has been a lot of discussion lately on the mail lists about Lustre maintenance releases and how it is determined which "feature" release gets additional maintenance releases. There is also confusion with regard to maintenance releases and the Community Tree maintenance contract. The contract specifically states:

"Ongoing Lustre development requires periodic Lustre feature releases which are fully tested and qualified Lustre releases featuring the latest code (both features and bugfixes) from the master codeline (git://git.opensfs.org / fs/lustre-release.git). It is expected that feature releases should occur roughly every six months. These are distinct from Lustre maintenance releases, which are funded by support contracts."

Basically, "maintenance" releases for each feature release are not covered by this contract and would not be feasible at the approximately four FTEs this contract funds. That being said, the CDWG is in a position to draft a recommendation regarding a long term support strategy for releases. Personally, I agree with Andreas Dilger who recommends that an Ubuntu-style "Long Term Stability" regular release strategy should be our goal. It is simply impossible in terms of resources to consider that each six-month feature release will have its own series of maintenance releases. 

Furthermore, to aid sites in planning for Lustre upgrade paths, we should decide on what will be the next LTS release well in advance of its actual release date. 

Therefore the discussion for the call today is to discuss a process for coming to consensus regarding the next maintenance release.

Regards,
Pam
