I've been following instructions from the latest Intel(R) Xeon Phi(TM) mpss_gold_update_3 README for NFS mounting to the Xeon Phi coprocessor (Section 7.6). After following all the steps, nothing seems mounted. When I try the "mount -a" command as root on the coprocessor, I get the error:
mount: RPC: Unable to receive; errno = No route to host mount: mounting host:/srv/michome on /home failed: Bad file descriptor
When I look in the /etc/fstab on the coprocessor, the appended line from the document:
172.31.1.254:/mic0fs /mic0fs nfs rsize=8192,wsize=8192,nolock,intr 0 0
has changed to:
host:/srv/michome /home nfs nolock 1 1
All the options have been removed, the IP addres sof the host has been changed and the two zeros on the end are now each a 1.
Anyone have an idea about what I've done wrong? (I assume that the /mic0fs and /srv/michome directories are correct from the instructions.) Or, if everything has been done correctly, is there an easy way to test? (I put a file in the host /srv/michome/micuser directory, but don't see it on the coprocessor.)
P.S. Is the NFS mount required to use the Xeon Phi?
