Netezza state stuck at Synchronizing

What does it mean if your Netezza state (when you run nzstate) is showing as synchronizing?

You will only see nzstate as synchronizing on Mustang servers. This is not a valid state in TwinFin servers.
This state means that the system is online i.e. is in normal working state but in parallel it is trying to write failed disk/SPU data from the secondary to new disk. The system state returns back to online once regeneration is complete i.e. data copy to new disk is complete.

Please note, depending on the data volume this process can run for couple of minutes to hours.Until the time regeneration completes the nzstate command will show status as synchronizing and users will be able to use system as normal except a minor degradation  in performance of the Mustang server.

In TwinFin and Striper series servers we do not have nzstate = synchronising. Rather during disk failure the system state remains online and synchronising process will run in background.
