How to check status of array, parity, parity progression and mover in script

[sjoerd]

Hey,

 

I'm tinkering with an 4x20 lcd display so I can show some basic info as disk- and cpu usage. cpu and disk usage is quite simple to get (/local/emhttp or something - found files there that are updated almost every second). But how can I get info if the mover is running or the parity status (oke, checking + percentage, not oke). I want this thing to start when unraid is done booting (so if array wont start i still can see that)
