It’s a data maintenance feature that amends data in storage pools that are incorrect or incomplete. It works on BTRFS volumes or RAID 5/6 storage pools. It’s scheduled to run monthly on my NAS. I guess it started now as I upgraded my drives from 4x4TB to 4x18TB.
When initializing a new array, it’s a (usually optional) process of zeroing out the newly added disks. Sometimes it’s required as part of calculating parity across the array (redundancy data).
What’s a data scrubber?
