[xcat-user] possible GPFS via NFS issue

[joseph.hargitai at nyu.e. (J. Hargitai)]

Cluster mounts /home 

from a storage node 

252 compute nodes mount it via myrinet via GPFS

4 user nodes mount it via NFS. (no myrinet) 

When user runs job and output is writen to /home/joe/xxx

output can be viewed/found from all compute nodes or storage node - 

but from user nodes - despite having /home and all old files - the new
output files are missing. They either appear much later - an hour - 
or you need to remount /home on user node and then files are visible.
