Missing Space in Volume

[gpalmer1981]

Hi All,

I hope someone can help me with this.  I have a volume on my netapp which seems to be missing space.  The space is aportioned as below:

vi_lonmail01_log

Total =               260Gb

Avail =               64.1Gb

LUNs =               1 LUN @ 112Gb

Snapshots =       2 Snapshots totalling 28.23Gb

But I seem to missing 60 odd GB.  does anybody know why this could be?

Hi and welcome to the Communities!

At first look it seems like fractional reserve kicking in.

See Chris's post for a very thorough explanation:

Kind regards,
