I've got a problem with Cloudstack not able to access the primary storage server I've set up for a new cluster. They're Xen 6.02 machines connected via SAS HBAs to a Dell MD3200. I configured the group in XenCenter, and have no trouble creating VMs in that environment. I can import them into Cloudstack, and the storage registers in Cloudstack using the PreSetup option, but the system VMs fail to deploy. Checking the error log, it looks like it cannot write to the primary storage. I've tried removing and adding the storage back in, but I cannot see any errors during that process.
This is a Cloudstack 4.0.1 environment that was recently upgraded from 4.0.0, the management server is running CentOS 6.2
