*There has been a lot of activity around self-extending layouts in master-next and things are looking good so far. It should land today and this will mark us being feature complete for this release.

*We are continuing to upgrade quite a bit on the lustre.org main site.  We probably have a few more days of updates to be 100% complete.
+
*Upgrading to Media wiki 1.3.0
*If anyone runs into any subtle issues with the site, please let Ken know.
 
*We are looking to do the mediawiki update in the next few weeks as well.

*Dustin:  We recently upgraded to 2.12.2 and, as part of that, we upgraded to zfs 0.8.1.  We ran into a dnode cache bug and it looks like other sites are also reporting it.  We are considering reverting to 2.11 and zfs 0.7.13.
+
*James is concerned that there are still issues with changelogs
**Peter:  Have you tried 2.12.2 with zfs 0.7.13?  You don't need to revert the Lustre version to roll back the zfs version.
+
*Peter suggested thinking ahead for 2.15 features for the roadmap to discuss next call
**Dustin:  Agreed that it is not a lustre issue, but since the customer is upset we are just going back to old image.
 
**Andreas:  We didn’t do much with 0.8.X and 2.12 since it was not released yet at the time of our testing.
 
**The issue is captured in https://jira.whamcloud.com/browse/LU-12510.
 
*Roadmap Discussion
 
**Andreas:  We may be able to put on immediate write resync, but that’s post 2.15.
 
**Cory:  In the 2.15 timeframe for Cray we are thinking of working on the hsm coordinator infrastructure, update to file copy tools to get it working between FLR and HSM.
 
**Cory:  We should probably update project page as part of the roadmap update, it is quite stale.
 
**Cory:  We would like to collaborate around metadata write back cache if possible, there would be value there on our side as well.
 
**Olaf:  James is concerned that there is still issue with changelongs and he is not the only one (LU-11426, LU-11205, LU-11581).
