Adding one more master to the cluster (quorum 1 to 2)
Hey,
Currently we are using 2 mesos master in our infrau. i.e quoram is 1.
We are planning to add one more master to the cluster to make quoram 2.
Does it need any downtime on our production ?
What strategies should we follow to avoid the downtime.
Thanks for any help !!

Documented the `--xfs-kill-containers` flag.
Added a description of the `--xfs-kill-containers` flag to the
`disk/xfs` isolator page and listed it in the upgrade documentation.

Fixed a disk space check in the XFS tests.
The XFS tests were requiring that at least 2MB of data was written,
but the test can still correctly pass after only 1MB had been written.

Increased the timeout for waiting for `reaped` to be invoked.
Previously after the container process is reaped by the Docker
executor, we will wait 3 seconds for `reaped` to be invoked.
However in some cases (e.g., launch a Docker container to use
an external rexray volume), there will be more than 3 seconds
after the container process exits and before the `docker run`
command returns (i.e., `reaped` invoked). So in this patch,
the timeout is increased to 60 seconds.

Re-enable epoll support for libevent.
Epoll support was disabled due to some undocumented "issues". Since
the original author is not responsive and a lot of libevent / SSL
issues have been fixed, we can try re-enabling epoll support.
Should this be an issue, epoll can be disabled once again using the
EVENT_NOEPOLL environment variable.

Author: Benjamin Mahler <bmahler@...>
Date: 2018-05-07T02:03:07Z
Disabled debug mode for libevent.
Debug mode enables additional tracking in libevent to check for common
errors. It is recommended to "only enable debug mode when actually
debugging your program" because "tracking which events are initialized
requires that Libevent use extra memory and CPU".
http://www.wangafu.net/~nickm/libevent-book/Ref1_libsetup.html
We could consider introducing libevent flags in order to be able to
toggle this behavior with an environment variable since it appears
that libevent does not provide one. However, since I don't believe
these assertions have been of value, we can just remove the debug mode
for now.

Failure to update registry should abort the master process.
When the registrar fails to update the registry it would abort the
actor and fail all future operations. However when the registrar
update is requested by an operator API such as a maintenance update,
the master process doesn't shut down (a 500 error is returned to the
client instead) and all subsequent operations will fail.
This patch fixes the specific maintenance API case but we can follow
up with other call sites or put a fix in for the registrar itself.

Made the 'SchedulerDriver' abort when operation's 'id' field is set.
Since the 'SchedulerDriver' does not support operation status updates,
this patch adds a check to the driver which will abort the scheduler
if the 'id' field is set in an offer operation.

commit 25176ed1b30a9f7fb82a71bca16a423343ba6d5c
Author: Benjamin Bannier <benjamin.bannier@...>
Date: 2018-05-08T15:58:12Z
Fixed flakiness in a `MasterSlaveReconciliationTest`.
The test `ReconcileDroppedOperation` uses detection of a
`ReconcileOperationsMessage` to confirm correct agent reregistration
behavior. For that it drops an operation on its way to the agent, and
then tries to observe the `ReconcileOperationsMessage` when the agent
reregisters after a simulated master failover.
Since `ReconcileOperationsMessage` is sent whenever the master detects
discrepancy between its own operation state of the agent and the
information sent by the agent in an `UpdateSlaveMessage` we need to
make sure to only drop the operation once the agent has sent the
update which is part of its initial registration sequence.

Added an option to keep downloaded patches to apply-reviews.py.
By default, the apply-reviews.py script will delete all patch files
it downloads. However, when a patch fails to apply, it might be
desired to edit and apply it manually. This change will make it easier
to do so.

commit 86523d3157d36bdaf4f7ce8fe001ae241e690a5f
Author: Benno Evers <bevers@...>
Date: 2018-05-08T17:02:51Z
Fixed flakyness in 'MasterAPITest.MasterFailover'.
This test used to be sporadically segfault as described in MESOS-8687.
The suspected cause is that a in a master actor, the `httpSequence`
field was lazily initialized in `ProcessBase::consume()` and afterwards
a call to `ProcessBase::_consume()` was dispatched, where it was
assumed that `httpSequence` is already initialized.
However, during this test the master actor would be destroyed and a
new actor would be spawned with the same PID. The dispatched method
would be called on this new actor and find `httpSequence` to be not
initialized, leading to a crash.
This patch introduces a call to `Clock::settle()` after the master
is shut down to ensure the outstanding `_consume()` gets discarded
before starting the new master actor.

Added token-based authentication for resource providers.
If a token is provided, it will be used in HTTP requests to the resource
provider manager. This allows JWT-based authentication and authorization
for resource providers.
The (unimplemented) credential support in `resource_provider::Driver`
has been removed in favor of the token-based approach.
