At least two users [1] are reporting that the operating version [2]
should be 30600 in 3.6.1 and not 30601 as convention might have it.
I don't care either way actually, but I just wanted to confirm this
isn't a bug in 3.6.1 so that I can patch puppet-gluster correctly.
Cheers,
James

How about you post a patch that adds this request as a comment in the
glusterfs sources (libglusterfs/src/globals.h)?
Good idea actually... Please review/ack/merge

James, why not just compute the operating version? After 3.5.0 it's always
XYYZZ based on the version.
Something along the lines of
$version_array = split(${gluster_version}, '[.]')
if $version_array[0] 3 {
fail
of GlusterFS, 3.7.
Cool, thanks.
As reference, the four line patch looks like:
https://github.com/purpleidea/puppet-gluster/commit/c2291084cf818d0058a66dcbc0984bcea7b51252
and is now in git master. Future patches are welcome :)

and I'd love to see either of these algorithms be part of Gluster
core...
As an aside, apart from Google's paper about chubby, are there any
good resources about how to understand Raft/Paxos on a Global scale,
in particular if latencies/links can be high/unreliable?

I will be talking in EuroBSDcon 2014 about porting glusterFS to NetBSD.
This is a conference with proceedings, hence I am writing a paper on the
topic. I am looking for a glusterFS expert that could point errors about
Does someone have an operating version table for GlusterFS?
These are the operating-version= values in glusterd.info
I'm looking to know which gluster versions, correspond to which
operating versions, eg:
'3.3' = '1', # eg: blank...
'3.4.0' = '2',
'3.4.1' = ???
and so on...

of how to parse the xml can be found in:

(although there are surely other better ways too!)

In addition, I would recommend considering using --xml and that
picking out the field you want to look at with a quick xml parser, and
then going with that directly. More stable than watching for a
specific return code.
Also, IANAL, but their code is GPL compatible, even if they are being
dicks and requiring copyright assignment for their proprietary dual
licensing. But at least their code is GPL compatible, which OpenSSL's
is not. So I say +1, use this.

/glusterd/glusterd.info has the seluser set as
'system_u', but something keeps changing it to 'unconfined_u' so
perhaps that is now what is correct. (It didn't used to be.)
What other files need attrs and what should they be?

was to delete the volume data from it, and re-create the volume. Not
sure if this is useful or not, but reproducing this is pretty easy in
case this uncovers a code path that isn't working properly.

Attached are all the logs. Hopefully someone can decipher this, and
maybe kill a gluster bug.

PS:
Cluster was a two host, Replica=2, single volume, with two disks each
host, all running in VM's.
