Abstract
A method of failure detection in a storage system is performed by the storage system. The method includes detecting a failure in a nonvolatile random access memory device that is in or coupled to a storage device having storage memory. The storage system has multiple NVRAM devices and multiple storage devices that have storage memory. The method includes taking a portion or all of the NVRAM device offline. Taking a portion or all of the NVRAM device offline is responsive to detecting the failure. Taking a portion or all of the NVRAM device off-line is while keeping online the storage memory of the storage device, sufficient ones of the NVRAM devices, and sufficient ones of the storage devices to provide reliable access to data and metadata in the storage system.
