[lustre-discuss] Lustre 2.10.3 on RHEL7.5 can't correctly mount from Lustre 2.8 server

[Kevin M. Hildebrand]

I'm not sure if this is a supported behavior or not, but I'm currently
unable to mount a filesystem from my 2.8 server on my 2.10.3 client.  Or
more specifically, the mount succeeds, but I'm unable to access any data
from the mount point.

The client is running RedHat 7.5 (3.10.0-862.2.3.el7.x86_64) with Mellanox
OFED 4.3.
I've also tried this from an Ethernet client running RH7.5 and get the same
behavior.

t2:~# cd /lustre

t2:lustre# ls
ls: reading directory .: Not a directory

t2:lustre# df -h .
Filesystem                                        Size  Used Avail Use%

/lustre

Should I expect this to work?

Thanks,
Kevin
