Hi Stefan,

Some responses inline (Adding to already expressed opinions from few users,
and some developers).

Status is surely 'Active'. Considering the project is of 13+ yrs, treat
current mode is 'low tide' in activity wave. But I want to assure, being a
maintainer, I would like to keep the project  active and will continue to
solve use-cases where it fits well.

Also, if you notice, we just recently had Release-8 planning meeting, and
the scope and future of the project leading to GlusterX (GlusterFS 10
release) is being discussed.

> So many people here reporting bugs and no solutions are in sight.

Sorry about that. I have to accept the statement with a pinch of salt.
There is no 'good' answer when a user is unhappy. But I want to write a
long answer for this particular point.

Like any 'open source' project, there are few commercially supporting
Enterprises backing Gluster, who still have many developers engaged in
making sure the project is active. But the fact is, a developer can pick an
issue to fix based on their 'employer' priorities. Sometimes, it so happens
that the usecases where there are problems in glusterfs may not be a
priority for most of the developers due to their employer priority.

As an individual contributor/maintainer for the project, the biggest
challenge in picking and fixing the issues which are complicated can be
listed like below:

* The problem may not happen when there is lesser load, or scale. Which
means, the fix would still be based on 'speculation' or 'knowing the code'.
Validate our fixes at scale is a challenge without a company support.
* We may not be able to reproduce the issue, which again would delay the
* The project itself deals with 'data', so many users may not be able to
provide more information, which again makes the delay.

All these issues aside, I want to take time and appreciate those users who
actively answer queries of fellow users, and keep the lights on in the
community. It is one of the major contributions anyone can give back to an
opensource community.

I should acknowledge the 'documentation', which would have 'recommended'
setup, is possibly out of date! We are on to fixing the documentation right

> Is it time to abandon this for production systems?

This is a very critical question. As person responsible for running an
infra for my company, I surely should be asking this question, especially
if things are not working out. Nothing wrong in you asking this. I would
say if you have production systems, consider talking to companies who
support the project etc, and have the alternative options properly thought

If interested, I am happy to make time and we can talk about particular
issues, and what do you expect to see, and give feedback. After that, you
can take decision on this.

> What are the alternatives?

Not a good person to answer. But would be great to know alternatives, so we
also learn what more we can do here.
