cDOT NFS - .snaphot directly automounting

Hello Guys,


I have seen a strange behaviour with Netapp Cluster Mode, when we do a NFS export to a unix server they can moun it correclty no issues.

After sometime when a new snapshots is created the Unix is showing up all the snapshots, as they are directly mounted on the system:


ubuntu@vx910:~$ df -h
Filesystem Size Used Avail Use% Mounted on
udev 12G 4.0K 12G 1% /dev
tmpfs 2.4G 1.2M 2.4G 1% /run
/dev/mapper/ubuntu--vg-root 28G 4.9G 21G 19% /
none 4.0K 0 4.0K 0% /sys/fs/cgroup
none 5.0M 0 5.0M 0% /run/lock
none 12G 144K 12G 1% /run/shm
none 100M 40K 100M 1% /run/user
/dev/sda1 236M 41M 184M 18% /boot 95G 21G 75G 22% /var/lib/graphite/whisper 5.0G 4.5G 535M 90% /var/lib/graphite/whisper/.snapshot/hourly.2016-02-04_1405 5.0G 4.5G 535M 90% /var/lib/graphite/whisper/.snapshot/hourly.2016-02-04_2005 5.0G 4.5G 535M 90% /var/lib/graphite/whisper/.snapshot/hourly.2016-02-05_0205 5.0G 4.5G 535M 90% /var/lib/graphite/whisper/.snapshot/hourly.2016-02-05_0805


In this case we dont want them to see this, as it is mounted directly. Instead they should be able to browse to the snapshot manually by getting into the .snapshot directory. (same behaviour as of 7-Mode)

when i tried to remount the shares and then i see only one nfs path mounted, but later i see this snapshots directory mounted again.
