We have built a couple SQL Server 2014 clusters with Cluster Shared Volumes and we've found that after a reboot the cluster service fails to come online. The error is access is denied to the C:\ClusterStorage. We have CU1 installed for SQL Server.
In order to fix the issue we have to boot the node into safe mode and delete the C:\ClusterStorage folder. Once we boot back into the system normally the C:\ClusterStorage folder is recreated and everything is fine. Until the next reboot when the same thing happens.
These are pretty basic installs where we followed the "Step-by-Step to Deploying Microsoft SQL Server 2014 with Cluster Shared Volumes" guide.
Does anyone know why the access is being stripped on reboot?
