Needed a way to report the provisioned space of a datastore cluster. With a regular datastore I can see this in the summary tab. But it seems to be missing for the Cluster. Once thin provisioning is heavily used, I see this value being used to ensure that provisioned space never exceeds capacity. Thus ensuring guaranteed space while allowing room for snapshots and reducing threat of a LUN off-lining due to snapshot growth. This is what I initially came up with.
$DataStoreClusters = Get-DatastoreCluster
ForEach($DSC in $DataStoreClusters){
$Provisioned = 0
$gDSC = Get-DatastoreCluster $DSC | Get-View
If($gDSC.ChildEntity.Count -gt 0){
$Datastores = Get-Datastore -Id $gDSC.ChildEntity
ForEach($DS in $Datastores) {
$gDS = Get-Datastore $DS
$Provisioned = [math]::Round(($gDS.ExtensionData.Summary.Capacity - $gDS.ExtensionData.Summary.FreeSpace + $gDS.ExtensionData.Summary.Uncommitted)/1GB,2) + $Provisioned
}
Get-DatastoreCluster $DSC | Select Name,CapacityGB,@{N="Provisioned";E={$Provisioned}},@{N="FreeSpace";E={[Math]::Round(($_.FreeSpaceGB),2)}}
}
}
