determine a power-up event after abnormal power-off; and
perform a roll-forward recovery for a memory system at least by:
determining a set of node blocks to be recovered; and
for each node block included in the set of node blocks,
determining a first data block stored in the memory system based on the node block;
determining whether first node address information retrieved from a metadata part of the first data block matches second node address information of the node block; and
