[lustre-discuss] problems mounting 2.9.0 server and older

I upgraded some of my clients to RHEL75 and Lustre 2.10.3

Now I can mount all my lustre FS which are 2.9.0 and older  (down to 2.4
) but I cannot see the directories.

ls: reading directory /lfs01:  Not a direcory
total 0

on another client with Lustre 2.10.1  I can mount and use the filesytem
from server 2.9.0 and older.

Am I reaching a compatibility issue trying to mount 2.9.0 and older from
a 2.10.3 client ?

thank you
