Re: [Gluster-users] How to stop glusterfsd ?

[Merlin Morgenstern]

thank you. that helped. Just for references the command is different in
3.7.x

instead:
sudo gluster v stop vol1

[Gluster-users] News of the week missing

[André Bauer]

Hey guys,

seems the news blog for last week(s) is missing?
Last one i found on the planet.gluster.org blog is for week 32:
https://atinmu.wordpress.com/2015/08/17/gluster-news-of-week-322015-2/

I already put some stuff in the Etherpad, if its because of lack of
news: https://public.pad.fsfe.org/p/gluster-weekly-news

Maybe its also an idea to switch to monthly news, if this would be
easier to maintain.

Maybe its also a good idea to have the news more prominent on
gluster.org. Maybe you could filter for news blogs (only) in the "Planet
Gluster News" section or have another "Gluster news" section?

Emne: [Gluster-users] "gluster v heal info split-brain" show solved split-brain

Hello all.
Today I had got a split brain on 2 node replica set installation.
I have solved problem by removing files from bricks.
find /storage/gluster_brick_repo -samefile 
/storage/gluster_brick_repo/.glusterfs/f7/bd/f7bdbdab-8dda-498f-ab03-6dcdfa2ed435
 -delete -print
But in output of "gluster v heal repofiles info split-brain" I still see 
removed file.
Try restarting self-heal-deamon.
http://article.gmane.org/gmane.comp.file-systems.gluster.user/21968/match=splitbrain+log+entries

How can I remove it from output of this command?

Re: [Gluster-users] Gluster 3.7 and OpenShift Enterprise v3

[Vijay Bellur]

On Sunday 06 September 2015 07:34 AM, Ryan Nix wrote:

Hello,

We're evaluating OpenShift v3, which uses Docker. The manual recommends
using NFS v4 for storage. I would much prefer to use Gluster's native
client instead of NFS, mainly because the Gluster client is so easy to
use. One of our Redhat SEs says it is probably fine to use Gluster
instead of NFS v4 for now until OpenShift gets formal support for
Gluster in OpenShift 3.1. I asked him why Gluster wasn't initially
supported and he said it probably came down to not having enough time to
test thoroughly before OSE's release.



Hi Ryan - I checked internally with the corresponding Red Hat teams and 
got a similar response. Lack of time is the core reason for going ahead 
with NFS. You can follow up with your Red Hat representatives to ensure 
that support for fuse lands in a subsequent OSE release.



Does anyone have any experience with running Docker images with Gluster
using the Gluster client? Is it possible that Redhat's recommendation is
based on the performance of NFS v4 vs Gluster?


No performance numbers have been gathered with fuse client in OSE and 
hence the question of comparison does not arise. What 
applications/workloads do you intend running in OSE?




I can't seem to find
anything that says one is faster than the other. Has anyone used Gluster
with Docker (which powers OpenShift)?



There have been various write ups on the web about using Gluster and 
Docker. I would be very interested if someone on this list has direct 
experience with this combination.


Thanks,
Vijay

Re: [Gluster-users] Gluster 3.7 and OpenShift Enterprise v3

[Ryan Nix]

Hey Vijay,

Thanks for the response.

OSE 3.1, due to be released late fall, is supposed to formally support
Gluster for persistent storage. Right now Gluster support is offered as a
technology preview. We're not planning on running any CPU or network
intensive applications on OSE, at least not yet. I've seen a few of the
write ups on Gluster and Docker, however, many of them seem to be about
running* Gluster in a Docker container* which is just mind blowing to me.
:)

I suppose we should simply try Gluster as the backend for OSE v3.0 and see
how it goes. We're not planning on launching OSE v3 in production just yet.
Sadly, we've had slow internal adoption of OSE v2.2. Developers seem to
have 99 problems and deployment/hosting isn't one of them.

But are there any performance benchmarks pitting NFS v4 vs Gluster client
3.7.x?

Thanks,

Ryan

Re: [Gluster-users] oVirt replacement?

[Sachidananda URS]

Hi Ryan,

Currently we have gdeploy which is a CLI for deployment and management of
Gluster clusters.
This is an ansible based tool, which can be used to:

* Set up backend bricks.
* Create volume.
* Mount the clients and bunch of other things.

The project is hosted at:
https://github.com/gluster/gdeploy/tree/1.0

I suggest using 1.0 branch, master is unstable and work in progress.

The tool is very easy to use. It relies on configuration files. Writing a
configuration file is explained
in the example configuration file:

https://github.com/gluster/gdeploy/blob/1.0/examples/gluster.conf.sample

A more detailed explanation of the fields can be found at:
https://github.com/gluster/gdeploy/blob/1.0/examples/README

`gdeploy --help' will print out help message on the usage.

Please let us know if you have any questions. It would be much awesome if
you can send us
pull requests.

Considering the flexibility of ansible and the ease of bootstrapping makes
it a choice of deployment.
