Because of the very low recovery parameters, there's on a single backfill running. `iostat -dmx 5 5` did report 100% util on the osd that is backfilling, but I expected that. Once backfilling moves on to a new osd, the 100% util follows the backfill operation.
Non-TLER disks can get 100% utilization when they're trying to relocate bad sectors long enough. But I also get 100% utilization when e.g. running mkfs so it's not a very reliable indicator either -- just like smart and dmesg...
