Abstract
Techniques are provided for key server and storage deadlock control. In an embodiment, a method is provided that includes determining a location identifier of a key server. The method further includes determining a first storage identifier based on the location identifier, where the first storage identifier identifies a storage volume that stores cryptographic keys of the key server. The method further includes determining a second storage identifier that identifies a storage device or storage system that stores data at rest encrypted by the cryptographic keys. The method further includes identifying a potential deadlock between the key server and the storage device or storage system based on the first storage identifier and the second storage identifier. The method further includes controlling the key server based on the potential deadlock.
