I am running the latest version of unraid, I am unable to create 2 separate cache pools. While each pool has a different name, and a single cache disk in each pool,, they are showing as combined size of 660gb and not 160gb/500gb. 

I have tried removing/recreating, they are both btrft, I cannot see other settings to change to make then behave a separate pools ?

Thanks,

Matt.

 

If they were originally in a single pool together at some point you will probably have to remove both pools, blkdiscard /dev/sd(whatever) on both SSD's, and then try again.

Thanks - Fixed.
Used fdisk -l, to find the right drives, then blkdiscard -f /dev/nvme____ and blkdiscard -f /dev/sd_ and created new pools.
