April 17, 20197 yr Hey all, I've gone through all the posts relating to this topic, and double-checked all my settings, but can't seem to find a solution. My Unraid 6.6.7 nvidia server consists of the following: 5TB Parity Disk 1 - 4TB Disk 2, 3 and 4 - 2TB Cache - 256GB SSD I have all my shares set up with High-water allocation method, minimum free space set to 0kb, automatic split as required, and disks set to ALL. However, the high-water doesn't seem to be kicking in as my Disk 1 is now down to 1.15TB free, and none of the other disks have come out of spin-down. I have a unionfs mount set up in /disks which includes my Gdrive mount and /user/media, which I thought could be part of the problem, but have confirmed that it points to /user/ and not /disk/. Any downloads go direct to cache, and then get moved to the array with Sonarr and Radarr. Anything else I could be missing? Unraid is starting to throw storage notifications and I'm getting a bit concerned. Cheers!

April 17, 20197 yr Author Even if it's a 4TB drive? I thought it did the first pass at 50% capacity. Thanks for the quick response!

The cut-overs are based on the largest disk. Since that is 4TB the first cut-over is 2TB. However since no drive is larger than 2TB and the 4TB drive still has 2TB free no cut-over occurs. As was said the next cutover-point will be 1TB. You willthen get 1TB written to each of the 2TB drives.

November 6, 20223 yr Same issue for me. I have 6 identical 18tb drives. Copying 75tb to the array, I'm 9.2tb in and it still hasn't switched from disk 1. Any ideas how to force it to move to the next disk?
