I have a 1TB NFS Volume on a NetApp that is showing 284GB of free space, with 739GB's free... the problem is, the Datastore is empty. No snaps, no dedupe, nothing.
We currently "ran out of space" on it, but come to find out, it wasnt really out of space. After evacuating VM's from the volume, we assumed it would be free space 900GB'sish. But its not. We have no snapshots, VSC isnt doing anything.
I've mounted the volume to a Linux machine (since its NFS) and here's the output:
Filesystem Size Used Avail Use% Mounted on
NFSCONTROLLER:/vol/DSNAME 1.0T 739G 286G 73% /mnt
Here's a LS command on the mount point:
linux# ls -al
drwxrwxrwx 4 root root 4096 May 16 09:48 .
drwxr-xr-x 23 root root 4096 Feb 13 11:00 ..
drwxrwxrwx 2 root root 4096 Aug 23 2012 .snapshot
drwx------ 3 root root 4096 May 2 2012 .vSphere-HA
The NetApp sees the same space free/used on that side as well. Not sure what else to do besides call support.

I meant "its" empty....
Deleting it is the easy solution, Im trying to find out why it happened.
Had to run it from the filer, but here's the output. Nothing thats 700+GB's

I think you must turn off options fractional_reserve=100 on your NFS volume
Show current settings:
vol options /vol/your_volume/
vol options /vol/your_volume/ fractional_reserve 0

Fractional reserve is already set to 0.
Here's the details for the volume:
nosnap=on, nosnapdir=off, minra=off, no_atime_update=off, nvfail=off,
ignore_inconsistent=off, snapmirrored=off, create_ucode=on,
convert_ucode=on, maxdirsize=327680, schedsnapname=ordinal,
fs_size_fixed=off, guarantee=volume, svo_enable=off, svo_checksum=off,
svo_allow_rman=off, svo_reject_errors=off, no_i2p=off,
fractional_reserve=0, extent=off, try_first=volume_grow,
read_realloc=off, snapshot_clone_dependency=off, dlog_hole_reserve=off,
