Abstract:
A method includes receiving a signal indicating a loss of power, starting a timer, the timer configured to expire after a specific time period, copying, by a distributed storage system having volatile memory configured as a write cache, write cache data from the volatile memory to a solid state device, upon receiving the signal indicating the loss of power to the storage system, configuring, the solid state device as both a read cache and the write cache, performing a health test on the storage system upon receiving the signal indicating the loss of power, and determining the loss of power as a false alarm if the timer expires and the storage system passes a health test on the storage system.
