[Gluster-users] Gluster Monthly Newsletter, April 2016

[Amye Scavarda]

Lots of people at Vault this week!

Last month's newsletter included a list of all of the Gluster related
talks, so if you're here, come by the Red Hat booth and say hi!


New things:
3.7.11 Released:
https://www.gluster.org/pipermail/gluster-devel/2016-April/049155.html

We've got a new Events (https://www.gluster.org/events/) page to replace
the publicpad.

updating the markdown page with your event!

Highlights from this past month's mailing lists:

++ gluster-users ++

Taira Hajime announced
https://www.gluster.org/pipermail/gluster-users/2016-April/026193.html the
general availability of Glubix 1.4 with support for Zabbix Server 3.0

Rajesh suggested using “--mode=script” option in order to enable non
interactive use of gluster snapshot delete. More at
https://www.gluster.org/pipermail/gluster-users/2016-April/026178.html

The 3.7.10 release continued to create conversations
https://www.gluster.org/pipermail/gluster-users/2016-April/026157.html on
the list
https://www.gluster.org/pipermail/gluster-users/2016-April/026164.html

Raghavendra Talur picked up a conversation thread on GlusterFS on HPC
cluster at
https://www.gluster.org/pipermail/gluster-users/2016-March/025595.html as
this has been requested earlier

++ gluster-devel ++

Atin discussed
https://www.gluster.org/pipermail/gluster-devel/2016-March/048926.html the
topic of brick port allocation by GlusterD and proposed a patch which
adopts an approach similar to snapd

With the 3.8 release process being more firm about the need to have well
written features pages, there appear to be a subset of features which are
now “at risk”
https://www.gluster.org/pipermail/gluster-devel/2016-April/049063.html
While 30Apr is the date by which this needs to be completed, both Niels and
Amye urge feature owners to work on squaring things away.

Jiffin reminded the feature owners about adding tests to the DiSTAF
https://www.gluster.org/pipermail/gluster-devel/2016-April/049104.html With
the framework having additional maintainers and more active development
https://www.gluster.org/pipermail/gluster-infra/2016-April/002075.html
inclusion of test cases by 30Apr is a requirement for consideration of 3.8
release feature completion

The location of the DiSTAF tests received a fair amount of conversation
https://www.gluster.org/pipermail/gluster-devel/2016-April/049057.html
intending to ensure that helper libraries and tests are appropriately
located to help packaging and wider adoption of the framework itself.

Karthik Subrahmanya provided an update
https://www.gluster.org/pipermail/gluster-devel/2016-April/049029.html on
his work on the WORM feature. Along with filing a bug I have filed a bug in
RHBZ #1326308 which now blocks the 3.8 release

Kaushal provided additional context around the 3.7.10 release
https://www.gluster.org/pipermail/gluster-devel/2016-April/049017.html
mentioning in detail the regression (which was also present in 3.7.9)

Vijay had asked for additional detail about coherence issues in context of
the SELinux client support in GlusterFS design
https://github.com/gluster/glusterfs-specs/blob/master/accepted/SELinux-client-support.md
which Manikandan had put up for review. Manikandan explained
https://www.gluster.org/pipermail/gluster-devel/2016-April/049099.html that
the work continues on invalidating the xattrs through the Upcall
Infrastructure which would handle the coherence issues.

https://github.com/gluster/glusterfs-specs/blob/master/under_review/quota-enhancements.md
is a design document posted by Manikandan
https://www.gluster.org/pipermail/gluster-devel/2016-April/049077.html
intended to improve the quota enable/disable processes. A patch is also
under review http://review.gluster.org/#/c/12952/
++ gluster-maintainers ++

Amye announced
https://www.gluster.org/pipermail/maintainers/2016-March/000520.html that
week of 28Mar would have the Jenkins infrastructure moved from iWeb hosting
to Red Hat’s data centers. Since this has potential impact on 3.7.10
release, the announcement was intended to seek agreement and make the
necessary changes. Michael Scherer reported back
https://www.gluster.org/pipermail/gluster-infra/2016-March/002045.html that
the migration was completed without hassles

Niels alerted the maintainers
https://www.gluster.org/pipermail/maintainers/2016-March/000526.html about
not merging patches with topic ‘rfc’ in Gerrit. He mentioned that without a
bug to track the changes it is difficult to build a query which lists all
the changes against the particular feature

Atin's note <
https://www.gluster.org/pipermail/maintainers/2016-April/000549.html> about
a regression around GlusterD failing to restart when volume has snapshots
spawned an entire thread to the feasibility of the 3.7.10 release.
Subsequently, a decision was arrived at to work towards a 3.7.11 addresses
this topic. More at <
https://www.gluster.org/pipermail/maintainers/2016-April/000589.html>

Small kerfuffle around a recent change which caused failures to build
artifacts was discussed at
https://www.gluster.org/pipermail/maintainers/2016-April/000562.html the
issue arose from the failures being not reported back to gerrit. Since the
report, it has been addressed and things are back to normal

The 3.7 release has not been without drama. Kaushal reported another set of
regressions, this time with management encryption enabled, daemons such as
NFS etc would not start. More at
https://www.gluster.org/pipermail/maintainers/2016-April/000604.html and
this is where the 3.7.11 release dates received some amount of serious
consideration and planning

Pranith’s intent to include the multi-threaded self-heal patch in a 3.7.12
release https://www.gluster.org/pipermail/maintainers/2016-April/000628.html
received a good amount of discussion with Niels highlighting the concern
around back-porting this to a 3.7 release because potential undiscovered
issues are something which is expected for new features and thus contain a
risk.
