Snapdrive snap restore fails to mount NFS volume

Hi

we have been testing SnapDrive 5.3 for Linux and CDOT 8.3.1P1.

The server OS is RHEL 6.4.

We have discovered that snapdrive snap restore fails when using NFS mounted volumes.

It looks like snapdrive initially unmounts the filesystem and then tries to mount it on a mountpoint created in the /tmp directory.

The command that is invoked looks like

mount -t <filer:/volume> /tmp/SDU_<datetimestamp>_<pid>

This fails because the fs type is not specified.

I ran the command using strace and I cannot see any attempt to determine the fstype.

Is this a bug or a configuration issue?

Thanks.
