Please try these:

  strace -o df.strace.out -v -e trace=statfs /nfs/eq-fas3240-001a/vol/a0content1/rcuvb/
  strace -o df.strace.out -v -e trace=statfs /nfs/eq-fas3240-001a/vol/a0content1/rcuniverse/

Then report back what they say.  (I assume that your system is using
statfs.  If that reports an invalid system call name then just report
all file system calls.)

  strace -o df.strace.out -v -e trace=file /nfs/eq-fas3240-001a/vol/a0content1/rcuvb/
  strace -o df.strace.out -v -e trace=file /nfs/eq-fas3240-001a/vol/a0content1/rcuniverse/

And if that fails then everything.

  strace -o df.strace.out -v /nfs/eq-fas3240-001a/vol/a0content1/rcuvb/
  strace -o df.strace.out -v /nfs/eq-fas3240-001a/vol/a0content1/rcuniverse/

If the file is large then please think of the list bandwidth and
compress it before sending it back.

Bob
