GlusterFS for Users
"GlusterFS for users" introduces you with GlusterFS, it's terminologies,
it's features and how to manage y GlusterFS cluster.

GlusterFS is a scalable network filesystem. Using commodity hardware, you
can create large, distributed storage solutions for media streaming, data
analysis, and other data and bandwidth-intensive tasks. GlusterFS is free
and open source software.

This session is more intended for users/admins.
Scope of this session :

* What is Glusterfs
* Glusterfs terminologies
* Easy steps to get started with glusterfs
* Volume topologies
* Access protocols
* Various features from user perspective :
Replication, Data distribution, Geo-replication, Bit rot detection,
data tiering,  Snapshot, Encryption, containerized glusterfs
* Various configuration files
* Various logs and it's location
* various custom profile for specific use-cases
* Collecting statedump and it's usage
* Few common problems like :
   1) replacing a faulty brick
   2) resolving split-brain
   3) peer disconnect issue

I was planning to give a talk on .meta directory and how that can be
used to debug a live file system. I could also talk about the statedump,
io-stats, etc.

They are available in the centos-gluster37-test repository. I have not
had feedback from anyone that these packages work fine, so they have not
been signed and pushed to the mirrors yet.

You can try them out like this:

  # yum install centos-release-gluster37
  # yum --enablerepo=centos-gluster37-test glusterfs-server

Please let me know if the packages work for you, and I'll mark them for
release. Updates are made available in the repositories on Mon-Thu. If
there is a reply from someone before Monday, 3.7.14 can get included in
the next batch.

Thanks,
Niels

It looks like many of the dependencies are not resolved. That is weird,
and I just tried it out in a local VM. For me this works just fine on a
new, clean, minimal CentOS-7 installation:

1. enable the Gluster (latest = 3.8) repo from the Storage SIG, the
   package is in the CentOS/extras repo, by default enabled:

# yum install centos-release-gluster

2. install the glusterfs-server package

# yum install glusterfs-server


All dependencies get resolved, including glusterfs-fuse, glusterfs-libs
and glusterfs-api that are missing for your try. The main mirror lists
all these packages too, I am not sure how they can be missing when you
use the standard repositories...
  http://mirror.centos.org/centos/7/storage/x86_64/gluster-3.8/

Could you try the above steps and check if that works for you? If not,
maybe clean the yum caches (with 'yum clean all') and retry.

HTH,
Niels

[Gluster-users] Talks and topics that need presenters (WAS: CFP for Gluster Developer Summit)

2016-08-13 Thread Niels de Vos 
In addition to Vijays request to submit talks, I would like to see some
very specific topics presented/demo'd. Anyone attending the Summit and
willing to take these on is very much encouraged to do so. To do so,
reply to this (or Vijays) email with your name and a description of the
topic.

If others would like to see other topics, please add them to the list.

Many thanks,
Niels


Practical Glusto example
 - show how to install Glusto and dependencies
 - write a simple new test-case from scratch (copy/paste example?)
 - run the new test-case (in the development environment?)

Debugging (large) production deployments
 - tools that can be used for debugging on non-development systems
 - filtering logs and other data to identify problems
 - coming up with the root cause of the problem
 - reporting a useful bug so that developers can fix it

Making troubleshooting easier
 - statedumps, how code tracks allocations, how to read the dumps
 - io-stats, meta and other xlators
 - useful, actionable log messages

Long-Term-Maintenance, Short-Term-Maintanance, releases and backports
 - explanation of the new release schedule
 - when/how are releases made, branching, stability phase etc...
 - the kind of backports that are acceptible and safe for minor updates

Documentation update
 - new Documentation Tooling based on ASCIIbinder
 - how to migrate different documentation sites for many of the projects
 - best location to report issues, submit fixes etc...
