Re: [Gluster-devel] Performance Translators' Stability and Usefulness

[Jacques Mattheij]

hello Anand, Geoff & others,

This pretty much parallels my interaction with the team about a
year ago, lots of really good intentions but no actual follow up.

We agreed that an automated test suite was a must and that a
whole bunch of other things would have to be done to get
glusterfs out of the experimental stage and into production
grade.

It's a real pity because I still feel that glusterfs is one of the
major contenders to become *the* cluster file system.

A lot of community goodwill has been lost, I've kept myself
subscribed to this mailing list because I hoped that at some
point we'd move past this endless cat and mouse game with
stability issues but for some reason that never happend.

Anand, you have a very capable team of developers, you have
a once-in-a-lifetime opportunity to make this happen please
take Geoff's comments to hart and get serious about Q&A and
community support because that is the key to any successful
foss project. Fan that fire and you can't go wrong, lose the
community support and your project might as well be dead.

I realize this may come across as harsh but it is intended to
make it painfully obvious that the most staunch supporters
of glusterfs are getting discouraged and that is a loss no
serious project can afford.

 Jacques
