Lustre discuss - Jan 2007 - 1.6?

Hi, everyone,

It seems like there''s been quite a lot of progress with Lustre fixes
and
improvements in the last few months; some of these have made it into 
Lustre 1.4 releases, while others are specific to the Lustre 1_5 branch. 
However, it''s been a while since the last 1.6beta, and it seems that 
1.5.95 is getting a bit stale...

Are there any plans to get a new beta out soon? There''s a lot of nifty 
patches in the Bugzilla database that would see much broader testing if 
they were integrated into a new release, and a new release might 
eliminate some of the problems that people report with 1.5.95, not 
realizing that patches are already available.  Performance improvements, 
NFS export fixes, MGS failover, 2.6.18 Kernel support, patchless 
improvements, numerous miscellaneous fixes and improvements... it''s a
very
impressive list (you guys have been busy!).

Alternatively, could anyone give a list of their "favorite" patches
that
seem to be significant improvements over the released 1.5.95? In 
particular, how are the various NFS reexport fixes and the 2.6.18 patches 
working for you? Have you tried the MGS failover patch? Anything else 
you''d recommend?

Thanks,

I would love to get another one out as soon as possible.  What''s gating
us at the moment is
our testing system (ltest), which has been pushed beyond its limits by 
the changes for 1.6
among other things.  We are in the middle of developing a new test 
system from the ground
up, but in the meantime that means we have even less time for 
babysitting betas.
We are reluctant to release anything (even for a beta) that has not 
undergone our full internal
test suite on multiple platforms; hence our lack of another release.
We have recently decided to again put a little effort to reinvigorating 
ltest for the 1.6 betas
for the reasons you mention, and hopefully this will bear fruit soon.
