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!
