There was an unexpected simultaneous reboot of devices within the cloud network. That resulted in network loss for all storage nodes within the cloud. Most of the virtual drives were returned to an active state, but there are still virtual drives shown in an "unavailable" state. We are working on restoring the storage operations for all virtual drives in the cluster.
