Occasionally I have to shut down due to maintenance in the home or other power issues.

 

Every time I power it back up, the system decides to do a full parity check. This takes a LONG time.

 

I'm pretty sure I'm shutting down properly (through putty, "shutdown now").

 

What am I doing wrong?

You're not shutting down correctly. If unRaid boots and detects that it was not shutdown cleanly it initiates a parity check to verify integrity of the data.

 

The correct way to shut down the server is via the webGUI. From the main page you need to click stop the array. Once that is done then click shutdown, also via the webGUI.

Usually that means that the system's last shutdown was an unclean one ...ie powerloss w/o an UPS, shutdown now via telnet will not stop the array & unmount drives properly (clean shutdown) unless you have a written script or do all of the required commands to perform via telnet.

There is also some unMenu shutdown options as well.

 

Hope this helps

Thanks very much guys. You've both answered my question. I will shut down using the webui from now on.
