Hi,

maybe i missed something or maybe i'm just wrong.


# cat /sys/block/bcache2/bcache/sequential_cutoff
512k

# cat /sys/block/bcache2/bcache/stats_five_minute/bypassed
64.3M

# dd if=/dev/zero of=/mnt/bcache2/ttt bs=4M count=1000 oflag=direct
1000+0 records in

# cat /sys/block/bcache2/bcache/stats_five_minute/bypassed

I also see only IOP/s an writes go to the SSD but not to the disk
behind. What's wrong?

Greets,
Stefan
