I think the nfs volume is exported with 700 as the permissions and root:root as owner. I cannot change it at the system level, and that needs to be done by IT on the volume/filer itself. Can you please ask them to change permissions to 755 so you can cd to it.
this is issue - What should be change from filer end in the export-policy ?
Superuser Security Types: sys -> this option should be changed to ?
