Dirty and cleaning of dirty data

[Stefan Priebe - Profihost AG]

Hi,

while having a system under heavystress - i was seeing the following:

Dirty Data on SSD: 35GB data
Writes to sata disk mostly 0-4mb/s

Why does bcache not start to clean this data to get free ssd space?

Right now the system is pretty slow as the caching device is very dirty.
