any idea why? newly setup system with only aggr 0
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

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.

you mean shrink aggr0?
here is what i have now

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

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.
