NW 7.6.3 NDMP Service Error: Filesystem traverse error

I'm getting this on a newly created Oracle 7420 cluster. This filesystem was copied from another NAS (Polyserve for Linux) that does backup with no issues using NW client for Linux. I tried to use savegrp -v -G NDMP but not much more info in the failure. I also just increased the group timeout to 300.

nas:/export/f0-fs2 savegrp: suppressed 13 lines of output.
