Component: engine
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.

Read configuration after flags making this the priority:
1- Apply configuration from file.
2- Apply configuration from flags.
Reload configuration when a signal is received, USR2 in Linux:
- Reload router if the debug configuration changes.
- Reload daemon labels.
- Reload cluster discovery.

This change will allow us to run SELinux in a container with
BTRFS back end. We continue to work on fixing the kernel/BTRFS
but this change will allow SELinux Security separation on BTRFS.
It basically relabels the content on container creation.
Just relabling -init directory in BTRFS use case. Everything looks like it
works. I don't believe tar/achive stores the SELinux labels, so we are good
as far as docker commit.
Tested Speed on startup with BTRFS on top of loopback directory. BTRFS
not on loopback should get even better perfomance on startup time. The
more inodes inside of the container image will increase the relabel time.
This patch will give people who care more about security the option of
runnin BTRFS with SELinux. Those who don't want to take the slow down
can disable SELinux either in individual containers or for all containers
by continuing to disable SELinux in the daemon.
Without relabel:

Provide a command line option dm.use_deferred_deletion to enable deferred
device deletion feature. By default feature will be turned off.
Not sure if there is much value in deferred deletion being turned on
without deferred removal being turned on. So for now, this feature can
be enabled only if deferred removal is on.
