NFS mount issue in cDOT 8.3.2RC2 - appears to only see the ROOT


Hi, I created a new volume on an existing SVM which is presenting NFS.


However, I am seeing the root (/) from the filer - : I think I have set my export-policy up correctly.

Cannot think what I have missed.


any ideas/tips appreciated.




[nfstest@llcnfs01v ~]$ showmount -e
Export list for
/ (everyone)


cat /etc/hosts       localhost       localhost.localdomain localhost4 localhost4.localdomain4    llcnfs01v.production.local      llcnfs01v    filer






From the filer side all appears ok:

some additional information.


our unix resource mounted /


filer:/ on /mnt type nfs (rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=,mountvers=3,mountport=635,mountproto=udp,local_lock=none,addr=


However, I cannot issue commands against this mount


ls /mnt, df /mnt, fuser all hang



[nfstest@llcnfs01v ~]$  sudo /usr/bin/umount -f /mnt
umount.nfs: /mnt: device is busy
