The present invention has been made to reduce influence of maintenance events on performance. Disclosed is a storage system that includes a plurality of storage nodes, each having an arithmetic device and a memory. Upon detecting a failure of a separate storage node in the storage system, the plurality of storage nodes take over the failed storage node by failover. When a maintenance event occurs in the storage system, the plurality of storage nodes change, according to maintenance event information, conditions for detecting the failure of a storage node related to the maintenance event, and restrict data input/output processing. The maintenance event information is the information regarding the maintenance event.
