I see to have fscked the /vol/vol0/etc dir:

admin:/mnt/filer-2/vol0# ls -la | grep etc d--------- 15 root root 28672 Apr 18 18:04 etc admin:/mnt/filer-2/vol0# chmod 755 etc chmod: changing permissions of `etc': Operation not permitted admin:/mnt/filer-2/vol0#

Moreover I am unable to change the permissions of any file/dir (through NFS).

What can be the problem?
