[Linux-cluster] GFS and samba problem, again

[sandra-llistes]

Hello,

I've installed RHES4 evaluation version with kernel 2.6.10 and GFS 
from CVS. In this environment with same samba configuration as Fedora, 
We've opened one file simultaneouslly from 14 PCs and it works fine.
I've proved with 2.6.10 kernel because Red Hat came with 2.6.9 kernel, 
but I wasn't able to compile with it, so I've probed next version.

I will try to copy same kernel+GFS and compile it in Fedora 5 to see 
if it works too.
Thanks,

Sandra Hernàndez
