Hi all,
A couple of weeks back I had sought inputs from you all on 3.2.0 and I had
committed to revert back
with an action plan to address all concerns/suggestions.
As you would have noticed, 3.2.1 was released a few days ago - already
addressing some of your
concerns. Please keep the feedback coming, inputs from the community are very
important to us.
Please find below responses to each of your concerns / suggestions :
*
**1) Stability : *(Paul simpson, James Burnash, Mohit Anchlia)
This is of utmost importance to us. We are investing more in QA engineers, QA
lead and also in
engineers who will dedicatedly work only on bug fixes. We are refining our
development processes
focusing more on quality and stability. We are increasing the test coverage and
automating the tests
along with more investments in lab infrastructure.
*2) Better way to handle errors and failures, better troubleshooting tools :
*(James Burnash, Whit
Blauvelt)
The scale of the number of components and systems involved increases the need
for better
troubleshooting tools and better handling of errors and failures. The recently
introduced
top/profile is a step in this direction to build diagnosability in to the
product. There was also an
effort on improving log messages in all modules – to make them more meaningful,
prioritizing them
appropriately, introducing new logs where necessary and things like that. The
recently completed
enhancements around logging in 3.2.0 is only the first of a multi-phase effort
to improve logging
and make the user experience much better.
*3) **Better documentation :* (Udo Waechter, Christian Kauhaus)
We are revamping the documentation and we should soon have more content in
existing sections and we
will also have new content – things like troubleshooting section, performance
tuning section, best
practices section are all in the pipeline. The format of documentation is also
due for a change shortly.
*4) **P**osix compatibility :* (Paul simpson, Udo Waechter)
We are fully committed to POSIX compatibility. Scenarios where it is not
compatible if any would be
high priority bugs for us.
*5) **Better self-heal / reporting on which files are not replicated :* (Paul
simpson, Whit Blauvelt)
This is already in our roadmap for 3.3. It is actively being worked on and we
can soon expect
improvements in this area.
*6) **NFS nlm locking :* (Paul simpson)
We do realize the need for NLM, I will get back to you all shortly on what our
plan on NLM is going
to be.
*7) **Ability to list config settings **(including **default**)**/ Performance
settings and
benchmarks : *(Mike Hanby, Udo Waechter)
The list of defaults is given in this blog post :
http://sacurs.blogspot.com/2011/05/glusterfs-defaults.html
And we also have a bug for this :
http://bugs.gluster.com/cgi-bin/bugzilla3/show_bug.cgi?id=2041
*
8) Bugs : *(Mohit Anchlia, Udo Waechter)
1) gfid mismatch issue : Is this bug 2522? Please let me know if you are
referring to something else
2) 0 byte file size : Bug 2922, we are working on it
3) Multiple files of same name showing up on the clent side : This problem too
will get addressed as
part of fixing 2522.
4) client hangs and crash : There are some related bugs which we fixed in
3.2.1, if this issue still
persists, we are committed to fix the remaining issues.
5) xattr mismatch on gluster mount points causing split brain errors : This
issue too is fixed in 3.2.1.
6) non-root owned files not shown : Bug 3030 has been filed to track this.
Thanks,
VS

Hi Vidya,
Thanks for asking. I think it will be worthwhile to look at the
archives and mailing list to see what other people have reported for
3.2. Few people already downgraded so not sure if they filed a bug.
But things that I have heard here:
1) gfid mismatch issue. Bug was filed
2) 0 byte file size. Bug was filed
3) Multiple files of same name showing up on the clent side
4) client hangs and crash
5) xattr mismatch on gluster mount points causing split brain errors.
Bug was filed
I certainly want to use 3.2 for geo-rep feature but problems that I am
seeing that others have faced has put me back and waiting for 3.2 to
become more stable. It will be really good to make 3.2 really solid
and stable.
Thanks

Hi,
for us, gluster 3.2.0 really messed up everything in a distribute/replicate
setup. Everything should be mentioned in this
thread.http://gluster.org/pipermail/gluster-users/2011-May/007705.html
The most important features for us would be:
1. 100% posix compatibility (this is already mentioned as a feature in the
FAQ!!!)
2. Better documentation. All the options and their settings do not really
explain what they do.
I could guess that performance.cache-size somehow influences performance,
but for us changing it to very high (4Gbs and more) and very low (128Mb) did
not change a thing. Same for stat-prefetch (which is supposed to makels
quickier) on/off: nothing. Would be nice to see some scenarios/settingsand
their benchmarks.
Thanks for the effort,
udo.
