Hi all,

We have a new filer running ontap 7.3.3.  We normally nfs export the /vol/vol0 to a select few hosts in order to do management on the filers (just the few things that filer view / system manager don't do well).  I can't seem to do it on this new filer.

filer3> exportfs
/vol/vol0/home  -sec=sys,rw,nosuid
/vol/vol0       -sec=sys,rw=ewsapps,root=ewsapps

I can do the following:
ewsapps:root:/ $mount filer3:/vol/vol0 /mnt
ewsapps:root:/ $cd /mnt
ewsapps:root:/mnt $ls -al
total 58
drwxrwxrwx   6 root     root        4096 Oct  6 11:21 .
drwxr-xr-x  39 root     root        1024 Oct  2 17:30 ..

ewsapps:root:/mnt $cd etc
ksh: etc: permission denied
ewsapps:root:/mnt $chmod 755 etc
chmod: WARNING: can't change etc


I've looked at options nfs, options cifs on the filer.  Can't see anything that stands out as would prevent me from changing etc.  I've done searches on NOW and google but nothing jumps out.

Anyone seen this?

thanks, Kevin
