Vivek Goyal 2e222f69b3 devmapper: Add a new option dm.min_free_space ... Once thin pool gets full, bad things can happen. Especially in case of xfs it is possible that xfs keeps on retrying IO infinitely (for certain kind of IO) and container hangs. One way to mitigate the problem is that once thin pool is about to get full, start failing some of the docker operations like pulling new images or creation of new containers. That way user will get warning ahead of time and can try to rectify it by creating more free space in thin pool. This can be done either by deleting existing images/containers or by adding more free space to thin pool. This patch adds a new option dm.min_free_space to devicemapper graph driver. Say one specifies dm.min_free_space=10%. This means atleast 10% of data and metadata blocks should be free in pool before new device creation is allowed, otherwise operation will fail. By default min_free_space is 10%. User can change it by specifying dm.min_free_space=X% on command line. A value of 0% will disable the check.
