_Missing space in Volume


I've a strange problem. Altough, to me it's strange.

One of our customers has a FAS2220. On it a employee created a Vol with a Total Cap. of 2.65TB.

It was used as a NFS store for VMWare to place VM's on it. At this moment there's (almost) nothing stored on it.

Snapshotting is off. There is no fractional reserve.

Still the filers reports this:


        VOLUME                                        AVAILABLE

     Total Data Space:     2.65 TB      Data Space:            1011.24 GB

     Snapshot reserve:     0 Byte        Snapshot Reserve:    0 Byte


     Data Space:                       5.42 GB

     Snapshot Copies Space:     0 Byte 

                    Total:                   5.42 GB

So somehow i'm losing 1.6 TB!

Does somebody where can it be or how I can trace it?



Re: _Missing space in Volume

what reservation have you got for snapshots?

what raid type are you using?

how large is your raid group?

Re: _Missing space in Volume

You missing space where? In aggregate? Please, please show output of "df -Ah".

Hi Virtualgeek2 and aborzenkov!


     I have no reservation for snapshots on that volume.

     Raid type:  RAID_DP

     I'm not sure what you mean with your third question but we have 2 aggregates. The aggr on which that vol resides has a Total space of 3.85TB from which 2.84TB is used.


     I'm missing space in that particular volume. It has a total space of  265 TB and about 1 TB is available. That means that 1.6 TB is in use, but I have no idea where or what.

     df -AH ouput:

Re: _Missing space in Volume

OK, then please paste output of “df -h volume”, “df -hr volume” and “df -hS volulme for the volume where space is missing. Please, paste text in message, not link images.

OK. I will paste text. Sorry for linking.
