IIRC you lowered *_promote_adjustment, but still full copy may be prevented by
sequential_threshold setting.
And how many blocks you have in cache after boot? [1]
Is number rising every boot?
Can you verify cache settings? [2]
[1]:
lvs -o+cache_total_blocks,cache_used_blocks,cache_dirty_blocks,
cache_read_hits,cache_read_misses,cache_write_hits,cache_write_misses,lv_health_status
[2]:
dmsetup status VG-LV
lvs -o+cache_policy,cache_settings,chunksize VG/LV
