I recently upgraded my array from 2x 1TB to 2x 16TB. The 16 TB are from a server part reseller, which I pre-cleared, found no errors, then rebuilt the array one drive at a time, starting with the parity drive. I am familiar with the fact that approximately 0.5-1% of the drive space will show as occupied, though my array currently shows ~370 GB used with 15.6 TB free. I only have 30-50 GB of data on the drives. Meaning ~300GB is essentially displayed as occupied on a clean drive.
Is this abnormal? I've tried searching for this issue but have only found people within the general percentage range I've included above rather than approximately 2% of the drive being occupied. I appreciate any ins
