FWIW, we''ve been running 1.6 clients with 1.4 servers without problems
for a
while. Note though that we don''t run patchless client. Here are the
exact
versions we currently use:
 client : lustre-1.6.4.3-2.6.9_67.0.4.EL_lustre.1.6.4.3smp
 servers: lustre-1.4.11.1-2.6.9_55.0.9.EL_lustre.1.4.11.1smp

Thanks for the confirmation.

I have a similar issue, but with different version *between servers*:
Is it acceptable to run MDS/MGS with lustre-1.6.5.1 but the OSSs with  
lustre-1.6.4.3?

An MDS update to 1.6.5.1 and RHEL-5.2 went fine, but the same on the  
OSS fails.
So, I am considering rollback of the OSS the 1.6.4.3 and RHEL-5.1  
which is working.
The clients are also a mix of the two versions mentioned.


Best regards, Michael
