    Hi,
    don't know if that be any of help, but I run below scenario with SATA
    and NVMe drives. For me, the issue is reproducible on NVMe drives only.

    Scenario:
    1. Create R5D3 with native metadata
        # mdadm -CR /dev/md/vol -l5 -n3 /dev/nvme[0-2]n1 --assume-clean
    2. Create FS on the array
        # mkfs.ext4 /dev/md/vol -F
    3. Remove single member drive via "--incremental --fail"
        # mdadm -If nvme0n1

    The result is almost instant.

    Thanks,
    Mateusz
