Hi all,
I've just run in to an issue mounting on a newly upgraded client running 2.12.5
with 2.10.3 servers. Just to give some background, we're about to replace our
existing Lustre storage, but will run it concurrently with the replacement for
a couple of months. We'll be running 2.12.5 server on the new MDS and OSSs and
I plan to update all clients to the same version. I would like to avoid
updating the existing servers though.
The problem is this. The servers have two tcp LNET networks, tcp and tcp1, on
separate subnets and VLANs. The clients only see tcp1 (a small number are also
on tcp3, routed via 2 lnet routers), which has been fine until now. With the
2.12.5 client, however, it is trying to mount from tcp. 2.10.3 to 2.12.5 is
obviously a bit of a jump, but does anyone have any ideas on what has changed
and what I could do here please?
