HI,

  It shows that you have allocated 675GB to vol0.

Volume                          Allocated            Used       Guarantee

vol0                                675GB          2002MB          volume

Total space available ithe aggr now is  69GB

Aggregate                       Allocated            Used           Avail

Total space                         675GB          2002MB            69GB

According to what ops mgr said:

>> Using 675 GB (90.67%) out of 745 GB

745-675 = 70 ~ 69 which is the Available space as shown in the filer.

For Analogy - See in my filer:

Volume                          Allocated            Used       Guarantee

vol0                                 64GB          5688MB          volume

root volume has been allocated 64GB

Aggregate                       Allocated            Used           Avail

Total space                        2823GB           758GB           920GB

Available space is like 920GB after allocating space to several volumes in aggr0

Hope this is useful.

Thanks,

  Arun

is this the default space that would be allocated to aggr0?

Not sure about that, but AFAIK you can always add disks to extend aggr0.

If you want to reduce the amount used in aggr0 - you can reduce the size of vol0.

Or reduce the size of the aggregate snap reserve.

vol0 has some default sizes it comes with.

No problem to use this command:

filer> vol size vol0 100g

to make it smaller and use the rest of aggr0 for something else.

Hi,

You can shrink vol0.

Also remember, A flexible root volume cannot be shrunk below a minimum size determined by the appliance model. This to ensure that there is sufficient space in the root volume to store system files, log files, and core files for use by NetApp technical support if a problem with the system occurs.

Check out this thread too: http://communities.netapp.com/message/63974#63974

Thanks,

i went ahead and resie vol0 on the aggr0.

now thast I freeed up some space on aggr0. is it possible to shrink the aggr0?

Sadly no you cannot shrink Aggr0. its capacity is made up of available space on all data disks in underlying raid groups. Once a disk is added into an aggregate it cannot be removed.
