If a VM fails to provision or power on, the problem is often related to degraded availability in the VSAN cluster or, more frequently, inadequate cluster storage capacity. In this recipe, we will address both of these very common provisioning/power-on failures.
You should be logged into vSphere Web Client as an administrator
You should be logged into RVC
If the failure is capacity-related, we will see an error message in vSphere Web Client along the lines of the following:
File [vsanDatastore] 3e192a55-c7ab-efa3-a51a-005056837d9f/linux-vm04.vmdk was not found
The policy requires 2 replicas with 1 disks each with 42949672960 bytes free each. Only found 0 such disks.
In this example, we know that the policy of the affected VM involves one host failure to tolerate because the VM requires two replicas. As each replica requires only one disk, we also know that the storage policy specifies a stripe...
