May 24, 20197 yr Hello, I have two SSDs setup as a cache pool. Total size shows about 200 GB. The mover is set to default overnight. The share is set to Yes for cache disk. Ran into an issue where I was copying files to the share and got error saying out of space. The array has 4TB capacity and I'm moving a few hundred GB right now. How does the cache work in this setup? Will it automatically move data to the array when full or only overnight as scheduled? For now, I've set the share to No for cache disk. Thanks.
May 24, 20197 yr Community Expert mover will only move data when it runs at its scheduled time. You can install the Mover Tuning plugin to get finer grained control over when mover runs. The other thing you should do is make sure that the the Minimum Free Space setting under Settings->Global Share Settings is set to be larger than the biggest file you expect to write. When the free space on the cache drops below that value Unraid will automatically stop trying to write new files to cache, and will start bypassing cache and writing directly to the array until space is freed up on the cache drive.

May 24, 20197 yr Author Thanks @itimpi for the tuner suggestion. I'll check it out. BTW, even with share set to No for cache disk, I got the same error no space left on device. Puzzling...

May 24, 20197 yr Author I changed the Min Free Space to 100GB. However, when attempting to copy, still getting the same error about disk space. Do I need to restart the array? EDIT: seems to be working now... thanks Edited May 24, 20197 yr by itlists
