METHODS FOR FILESYSTEM METADATA CACHING TO IMPROVE FAILOVER PERFORMANCE AND DEVICES THEREOF

A method, non-transitory computer readable medium, and device that assists with caching filesystem metadata to a partner non-volatile random-access memory (NVRAM) includes caching metadata related to an incoming data modifying operation generated by a client computing device to at least one storage controller device in a cluster. A service interruption event that makes a data block present in the storage device of a hosting storage node inaccessible to the client computing device is determined for during the caching. The requested metadata block from the at least one NVRAM is retrieved when the service interruption event is determined. The cache is warmed using the retrieved metadata block from the at least one NVRAM.
