Abstract
A memory tier including persistent memory (PMEM) devices is established in nodes of a cluster system having a deduplicated file system. At least a portion of metadata generated by the deduplicated file system is persisted to the memory tier. The portion of metadata includes an index of fingerprints corresponding to data segments stored by the deduplicated file system to a storage pool. A determination is made that an instance of the deduplicated file system has failed. A new instance of the deduplicated file system is started to recover file system services by loading the index of fingerprints from the memory tier.
