Also, is 1.5.90 synchronized with the 1.4.7 Beta 1 release? Does it 
include the same bugfixes and improvements? Those improvements appear to 
include kernel 2.6 NFS exports; is that correct?

Many Thanks,

Brent

I noticed the Bugzilla 10193 fix in the changelog. So, does the 1.4.7
Beta 1 release include a patchless Lustre client?

Thanks!

Unfortunatelly we have at least one problem report for Ubuntu Dapper.
They build their kernel with gcc4 and that one does not work well with
Lustre (yet?), making it to eat way too much stack space and quickly
overflow kernel stack leading to all kind of bad crashes as the result.
Recompiling everything with gcc 3.4 seems to have fixed things, though.

As Andreas said, even though many changes went in, the 1.4.7beta1 itself
does not contain full patchless client.
I have uploaded 1.4.7beta1 with patchless client support to
ftp://ftp.clusterfs.com/pub/people/green/patchless
There is no patchless server support this time due to lack of time.
Patchless client will go into one of next official 1.6.0 betas.

Bye,
    Oleg

The 1.4.7 release does not contain the full patchless client.  A lot of
the required changes for patchless client are in 1.4.7 but not all of them.

Yes, the 1.5.90 and 1.4.7 b1 releases are fairly close in terms of fixes,
but I don''t think they are identical.

correct?
Yes, I believe this is one of the 1.4.7b1 features that is included in 1.6b3.

Yay!

Hopefully this will mean that we''ll be able to run lustre clients on
unpatched
Ubuntu Dapper (2.6.15 kernel, including the needed patch for recursive 
symlinks).

Now we''ll just need to get the debian/ubuntu packaging fixed and then
there
won''t be many excuses left for not making Ubuntu an officially
supported distro
for Lustre ;)

Ah, I actually have no idea who built the kernel in question.
And I have no Ubuntu to take a look.

Just a heads up: I''m not sure about Dapper, but most debian and
ubuntu/breezy use 3.4 to build the kernels. The only situation where I
saw kernels compiled with gcc4 was when people trying to compile a
kernel themselves and using the default compiler.

That was me.  I''m not 100% certain that I tried with a stock Ubuntu
Dapper
kernel as well (I was tinkering with patchless server, and so I added the 
recursive symlink patch), however a quick Google turned up this thread:

https://launchpad.net/distros/ubuntu/+source/gcc-3.4/+bug/44139

This seems to indicate that they exclusively use gcc4 for the kernel now 
and want to see any legacy drivers catch up.

gcc4 definitely caused mdt problems (patchless and patched).  I am not 
certain, though, that it caused patchless client problems.  It might 
work...

Thanks,

Brent
