Have an SSD Cache setup on my Drivepool thats being used for an NVR, but still hear constant noise from the mechanical archive drives

[bobloadmire]

I bought an ssd to use as cache, so it could fill it, and then once a day dump the cache to the archive drives, rinse repeat. but now that the archive drive has filled up, I hear constant clicking from writes to the drives 24/7. Is there anyway to setup a scheduled dump of the cache to the archive drives so they can idle for the vast majority of the day?

Absolutely:

Change it to not balance immediately, or increase the "not more often[...]" value.

hmm i'm set to balance daily at 3am. my ssd cache is constantly sitting full, advice?

Then the "balancing immediately" and checking the "but not more than once ever X hours" option may be better, as this should balance the data periodically and be a bit more aggressive than the "balance daily" option. 

However, you may still end up with other drives being active, depending on how much data needs to be moved, and how long that takes. 

Eg, there may not be a good solution that will prevent the hard drives from being used.  It may be simply a matter of finding a balancing that works while making compromises.
