Hi Winnie,
Since 2017. Yes it was around 9% for the various things ixApplications housed on the pool after a prune in August.
I’ve shown the output from smartctl -a /dev/nvme1n1 above, below is nvme2n1, is this what you’re after?
root@truenas[~]# smartctl -a /dev/nvme2n1
smartctl 7.4 2023-08-01 r5530 [x86_64-linux-6.6.32-production+truenas] (local build)
