What does "running green LED" mean? Is this the normal running state?

Quote:I'm also wondering about something else - the unit has 8 disks - 6 are in RAID5, 7th is spare and 8th is an SSD as cache. Wonder if that has anything to do with it. I don't remember exactly when I fitted that - but definitely could be around same time as I noticed this wasn't sleeping either. Just wonder if there is something there - when MS is off, no caching and when on - some form of caching going on (leading to read/writes etc)? Possibly, but just a theory...

I did notice some entries in the disk I/O log about CACHEDEV2_DATA.log. This is presumably related to the cache. I don't know enough about how QNAP caching works to understand whether this could be the cause. Can you disable the cache as a test to see if this allows spin-down to happen?
