Topic
Updated packages that resolve various issues are now available for Red Hat
Enterprise Linux OpenStack Platform 7.0 (Kilo) for RHEL 7.
Description
Red Hat Enterprise Linux OpenStack Platform provides the facilities for
building a private or public infrastructure-as-a-service (IaaS) cloud
running on commonly available physical hardware.
This update addresses the following issues:
- Previously, the logrotate configuration attempted to call the old
SysVinit rabbitmq script in the postrotate section, which is no longer
used on Red Hat Enterprise Linux 7, resulting in log rotation failing
to close the rotated files.
With this update, the rotate-logs action is directly invoked via the
rabbitmqctl command. As a result, the log are rotated correctly. (BZ#1252842)
- Previously, a connection-level event handler in SQLAlchemy was invoked
with the wrong state when a database reconnection attempt had failed. A
separate change introduced in SQLAlchemy 1.0.2 made a slight change to
the scope of the connection-level datastructure (Connection.info) during
the reconnection process. The oslo.db OpenStack library depends on the
state, which it stores in the datastructure within the event handler,
and due to these two changes together, the datastructure unexpectedly
blanked out if multiple reconnection attempts failed before eventually
succeeding. As a result, when OpenStack applications attempted to recover
after an unexpected database disconnect, they would in some cases encounter
this situation, raise a stack trace from within oslo.db and fail to
continue.
With this update, the rebase of SQLAlchemy to version 1.0.8 fixes the issue
with the event handler so that the correct state is passed to the
connection event, allowing oslo.db to correctly maintain the information
in Connection.info it expects, resulting in the multiple database
reconnection attempts in OpenStack applications no longer causing oslo.db
to fail. (BZ#1245639)
- Previously, the GM process would send a message for all slaves to
terminate once the master process terminated, but would not wait for
confirmation that the slaves had received this message before terminating
itself. As a result, a slave that did not receive the termination message
would detect that the master GM process had terminated, and would promote
itself to master, causing the previous master process to hang indefinitely.
With this update, the GM process now waits for its broadcast buffer to
empty before terminating. This results in all slaves receiving the
message to terminate, allowing the master process to terminate as
expected. (BZ#1250673)
Solution
Before applying this update, ensure all previously released errata relevant
to your system have been applied.
Red Hat Enterprise Linux OpenStack Platform 7 runs on Red Hat Enterprise
Linux 7.1.
