HI,

Can you paste the output of "aggr show_space aggr0" ?

Thanks,

Arun

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?

arunchak — Sat, 10 Sep 2011 03:58:04 GMT

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.

sorry i mean vol0? its ok to shrink that? do I need to run space reclaming?

Re: aggregate full

arunchak — Mon, 26 Sep 2011 01:13:13 GMT

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.

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?

Re: aggregate full

rorzmcgauze — Mon, 14 Nov 2011 17:12:46 GMT

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.
