Hello,

I need an information,

I have an s2d cluster with a csv configured with mirroring.
I'm having storage capacity overloading situation, and i'm analyzing the situation.
I listed all the vm's storage, and counted their storage, but i'm seing there is a delta between all the vms storage (disks) and the used capacity in the csv, i want to know where this delta come from, and specifically i want to know, when configuring a csv with mirroring, it consume the storage on the csv level (for example, if i create a csv of 20TB, the mirroring will consume that 20 TB as s vm's disks, which mean that 20TB is not completly available to VMs), or the resiliency is consuming storage at the storage pool level?

Thanks

    Hello there,

    This might not be captured by the resiliency.

    If it is then the Set-ResiliencySetting cmdlet modifies the properties of the specified resiliency setting name. For example, the user can specify that when creating any new virtual disk using the resiliency setting named Mirror, that the default interleave value would be 128K, or to define the default number of columns to use when creating a Simple (stripe without parity) virtual disk.

    Hope this resolves your Query !!
