Well, my first Lustre test was crashing on every 'write' operation.
Them I enabled LVM and it worked. I'm using only the vanilla 2.6.12.6
kernel with the lastest 1.4 release.
I'd say something's manged in your kernel/patches. Perhaps due to 1.4; I went
to 1.6 as soon as I was able to, and have no experience with the latest and
greatest 1.4.
Question: would you use Lustre 1.6 now or you would wait until the
official version is out?
If I had to ship today, I'd probably ship the 1.6b5 code. I find lustre 1.4
much more of a headache to configure and manage. Thankfully, I don't have to
ship today; I expect by the time I do, cfs will have released the real 1.6
code.
Question: do you expect in upgrade incopability between the current
1.6 beta and next betas or the official version?
What variety of incompatibility? On-disk format? On-the-wire format?
Something else? The short answer is no, in general the cfs guys seem to do a
pretty good job at making that stuff backward compatible. Having said that,
there was some kind of an incompatibility between 1.6b4 and 1.6b5. So I guess
they don't get it right all the time :-}
The slightly longer answer is "ask cfs". I believe the answer you'll get is
that they claim compatibility for one prior release, and that they make no
claims about compatibility of beta code with anything else.
