Hi all,
I came across this blog entry. It seems that there's an undocumented
command line option that allows someone to execute a gluster cli command on
a remote host.

Hi Yong,
Gluster uses the openssl library, which supports SSL 3.0 and TLS versions
1.0,1.1,1.2. I actually don't know if its dynamically linked against the
openssl library nor what version of the openssl lib gluster has been tested
with. That is important info to know that is currently undocumente
Hi all,
I have gluster 3.9. I have MTLS set up for both management traffic and
volumes. The gluster fuser client successfully mounts the gluster volume.
However, I see the following error in the gluster server logs when mount or
unmount happens on the gluster client. Is this a bug? Is this anythin
any URL related to setup & configuring MTLS is appreciated.

Hi Deepak,
Here's the TLDR
If you don't want the I/O path to be encrypted but you want to control
access to a gluster volume, you can set the auth.allow and auth.reject
options to whitelist and blacklist clients based on their source IPs.
There's also always iptables rules if you don't want to do
Hi all,
I found this doc on georeplication. I am on gluster 3.9. I am looking for
documentation that explains how to failover between the master and slave
volumes.

How would someone handle the following scenario.

Hi all,
I am happy to report that I finally got a container in an openshift pod to
mount a gluster volume successfully. This has nothing to do with gluster,
which works fine, and everything to do with openshift interfaces being less
than ideal. Note to self: turn off the settings in openshift that

Hi all,
Has anyone had success getting openshift to use gluster volumes as
persistent volumes in docker containers? I am quite confident that gluster
has been configured properly.
However, when the pod attempts to mount the gluster volume this error
occurs.

I can see through the API there's a distinction between pool and a peer. My
question is what distinguishes a pool member from a peer? If a node is one
it always seems to be the other. Can I ever have a node be "online" in a

Hi all,
I want to use lvm for two reasons:
- gluster snaphosts
- ability to dynamically add space to a brick.
Here's what i'd like to do:

2. create a single volume group from those physical volumes
3. create a single logical volume
4. make the single logical

I read this in the gluster docs. Note I am not using arbiter -- I am
setting up volumes with full 3 replicas. In this case, is this split brain

chances that this could happen? In other words, aside from doing regular
snap
the right way to do this or should be handled differently?

I am quite new to gluster so this is likely my lack of knowledge. Here's my

My understanding is that in gluster 3.3, a check was added to see if a
directory (or any of it's ancestors) is already part of a volume. So far so
good. However, I believe this check may be inappropriately getting applied
in my case.

All:
According to the docs, when you initially set up a gluster storage pool,
the first two servers need to probe each other. However, after that, you
add additional servers in by probing from a node that's already in the
pool.
However, when I follow the directions with gluster 3.8, the behavior

Hi Atin,
I assume you are referring to the /var/log/glustershd.log. If so, that file

Hi all,
I have recently started exploring the DFS solution space and was doing some
basic setup and testing with gluster. I set up a pool of three nodes
following the quick start guide. That seemed to work fine.
However, shortly after that, I noticed that one of the servers in the pool
was becomi
