Why is the used percentage different in Linux from the one in NetApp?
Applies to
ONTAP 9
Answer
In Netapp, the volume size is: Available size + Netapp used size + over provisioned size.
In Linux, the volume size is: Available size + Linux used size.
Linux used size = Netapp used size + over provisioned size.
Example:
The volume shows:
Vserver Volume Aggregate State Type Size Available Used%--------- ------------ ------------ ---------- ---- ---------- ---------- -----Vserver1 vol1 - online RW 480TB 65TB 69% By going to Active IQ > Autosupport > Volume.xml, we can see that here we have :
- volume size: 527765581332480B (=480TB)
- available size: 71635437178880B (=65TB)
- used size: 363887210782720B (=331TB).
- Over Provisioned Size: 92242933370880B (=84TB).
The Netapp used size percentage is therefore 331/480= 69%.
But with Linux, we will get:
Linux used size = Netapp used size + over provisioned size = 331TB + 84TB = 415TB.
The Linux used size percentage is therefore 415/480 =86%:
Filesystem Size Used Avail Use% Mounted on10.10.10.4:/vol1 480T 415T 65T 86% /vol1 .
