Hi Leonardo,
I am aware that sequential IO is routed directly to the backing
device. And I also played with the parameters like
sequential_threshold and the write_promote_adjustment introduced
in 3.14.
To test this i ran ./fio --name=test
--filename=/dev/mapper/dmcache --rw=randwrite --filesize=16G
--bs=64k --ioengine=libaio --direct=1 --iodepth=1000 in a endless
loop.
Regards
Christoph
