What in the world have I messed up on my balancers?

[JTScribe]

Accidently bumped the reset toggle and have been trying to get things set back the way they were. For some reason it wants to fill up some hard drives almost to capacity whereas before it left the archive drives balanced and emptied out the cache drives as needed. Help?

Sorry, I'm stumped. Your settings look like they should be resulting in an even distribution. Is there anything active at all in the File Placement tab, or lower down in the Balancers tab? Is "Balancers -> SSD Optimizer -> Ordered placement -> Duplicated" unticked?

Does changing to "Equalize by the free space remaining" have a better result?

Setting the balancing ratio to 100% may help.

But to be blunt, the SSD Optimizer and the Disk Space Equalizer balancer are at odds.   The Disk Space Equalizer wants to fill every drive, equally, but the SSD Optimizer wants to clear out several of the drives.

Both duplicated and unduplicated are unticked. Changing the toggle between equalize by free space did shift things around a little.

Is there a best practice to use SSD optimizer and keep things balanced on the archive drives? Should I stripe the SSDs in Windows, maybe?

If you want to use the SSD Optimizer and use the rest of the pool,  the "simplest" option may be to use hierarchical pools.  Eg, add the SSD/NVMe drives to a pool, add the hard drives to another pool,   and then add both of these pools to a pool.  Enable the SSD optimizer on the "pool of pools", and then enable the balancers you want on the sub-pools.
