I do the OFED distro ports for NFSRDMA. It will be supported on
CENTOS 7 in OFED 3.12.1 (coming soon). Not sure how this relates
to MPSS/OFED.<br>

I’m aware of that restriction. I was just mounting a host-exported share on a different host.

Subject: [ewg] Problem with NFS/RDMA on CentOS 7 with OFED-MIC-3.5-2-
rc1
Hi,
I'm trying to get the new 3.3 MPSS stack to work together with OFED-MIC-
3.5-2-rc1 on CentOS 7, but I've run into a problem with NFS/RDMA: While I
can mount file systems and traverse them, I cannot access any files larger
than about 800 bytes. Trying to cat such a file results in errors like
this:
cat: gcc.lua: Input/output error
or, when copying:
[root@node01 files]# cp test.txt /tmp
cp: error reading 'test.txt': Input/output error
cp: failed to extend '/tmp/test.txt': Input/output error
[root@node01 files]#
At the same time, trying to write a file that is larger than 800 bytes to a server
running CentOS 7 tends to freeze that server, while writing to a CentOS 6.5
server works just fine (I just can't access the data afterwards).
On the other hand, exporting an NFS share on a CentOS 7 server and
mounting it on a CentOS 6.5 client works without any problem.
We are using Mellanox ConnectX-3 VPI adapters (mlx_4 driver) and are
currently running kernel version 3.10.0-123.4.4.el7.x86_64. Does someone
have an idea of what might be going wrong here?
Thank you!
