re: How to Run ChkDsk and Defrag on Cluster Shared Volumes in Windows Server 2012 R2

Hi,

I consulted the defrag team and here's what is going on... You might need to contact NetApp to help you fix this.

Reference this: msdn.microsoft.com/.../hh449432(v=vs.85).aspx and tell them the violation is that OptimalUnmapGranularity or UnmapGranularityAlignment aren’t multiples of cluster size.

Your cluster size isn’t a multiple of slab size (OptimalUnmapGranularity) and slab alignment (UnmapGranularityAlignment). If you know the slab size, you can choose a cluster size that meets these requirements.

So the options for you might be to

1) Contact NetApp, find out the values of the slab size and slab alignment change your cluster size to be a multiple of this.

2) Contact NetApp to change the value of your slab size and slab alignment to be conformant.

Hope this helps!
