[lustre-discuss] lustre 2.5.3 servers and lustre 2.10.4 clients?

[Chris Roome]

Hi lustre gurus,

We have the MGS/MDT and OSSes on lustre 2.5.3 and we would like lustre 
clients on CentOS 7.5.1804.

I did some testing with 7.5.1804 and 2.10.4.RC2 on a test client and had 
no problems (other than the "Lustre: Server MGS version (2.5.3.0) is 
much older than client..." warning).

Looking through the mailing list I found reports of people using 2.10.1 
clients with 2.5.3 server without any problems.

Would it be fair to say that there shouldn't be any problems with 2.10.4 
clients with 2.5.3 servers since it seems 2.10.1 works OK?

The plan is to upgrade the servers later in the year.

Thanks for any guidance!

Chris.
