RHBA-2015:0928 - Bug Fix Advisory

Topic

Updated packages that resolve various issues are now available for Red Hat
Enterprise Linux OpenStack Platform 6.0 (Juno) 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:

This rebase package includes a notable fix under version 5.5.41:

• With this release, mariadb-galera is rebased to version 5.5.41, fixing the

memory barrier problem in InnoDB/XtraDB mutex implementation, which caused the
server to stall or hang. (BZ#1203009)

• Prior to this update, freeform options could not be passed to MKFS from DIB,

even though the FS type was modifiable.
Consequently, when building an ext4 FS on Red Hat Enterprise Linux (RHEL) 6 from
a RHEL 7 build host, the 64-bit flag was set, resulting in a non-booting VM.
This fix addresses this issue by adding the mkfs-options arg to the
disk-image-create script, allowing arbitrary user-defined options to be passed
to mkfs.
As a result, fully booting ext4 FS can be built on RHEL 6 from RHEL 7, and as a
side benefit, users now have a hook to specify many properties of their
filesystem which were previously locked without code modification. (BZ#1206676)

• Prior to this update, the openstack-trove-guestagent service may have failed

to start if the underlying database was not running. This update ensures that
the MariaDB service is running before starting the guestagent. The workaround is
to first start the guestagent service. (BZ#1209584)

• Previously, SELinux blocked Compute from spawning an instance when using live

migration with NFS storage.
Consequently, Compute was prevented from creating instances.
This update allows virt types to write to Compute file types, and as a result,
Compute is now able to spawn an instance. (BZ#1211628)

Solution

Before applying this update, ensure all previously released errata relevant to
your system have been applied.
