Hi all,
I searched for an answer on my question but the things I have read don't clear this up for me.
I have the following situation:
aggr show_space -h aggr0
...
Aggregate | Allocated | Used | Avail |
Total space | 9570GB | 7300GB | 1583GB |
Snap reserve | 590GB | 183GB | 407GB |
WAFL reserve | 1312GB | 136GB | 1175GB |
Now I already figured out that Snap reserve and WAFL reserve is already substracted from the Total Sapce (Avail).
However I wonder if apart from these reservations I should still keep a certain percentage of free space.
We are creating 1.3TB volumes with in it a 1.1TB lun. The luns are thin provisioned but they can have enough space to be fully filled.
The snapshots are hold on the same volume. I would really like not to size the existing volumes down as that might give issues with the snapshots(snapshots are deleted when not enough free space is available).
My question is, can 1300GB be allocated here? Or would that be a problem for performance, ...
When I look with df -Vh I see that the volumes on that aggregate are far from full.
Is netapp taking into account the actually used space or the full space that is "handed" over to a specific volume, even that space in the volume is not fully used?
So is the 1583 really usable, or do I still need alot of this space free to make sure I don't run into issues?
Note that dedup is active as well.
Thanks alot in advance!
