performance and security.

The previous default of writing zeros over deleted volumes took a

significant amount of time, and may not be needed. One can now

set a global configuration setting to clear only part of a volume

(to remove encryption keys for example), or to disable clearing

completely.

Additionally a new 'shred' capability is available to overwrite

with random data instead of zeros.

Foreman now installs the 'tuned' service and its related

Virtual_host profile to Compute nodes. This service optimizes

Compute nodes to improve the performance of hosted guests.

Feature: HA All In One Controller host group should allow setting

Block Storage backend mount options.

Reason: This enhances Block Storage availability via RHS.

Result: Gluster shares for Block Storage are specified using

"glusterfs_shares" parameter on quickstack::pacemaker::cinder

class. The value should be array of Gluster shares, and can

contain mount options.

Example:

["glusterserver1:/cinder -o backupvolfile-server=glusterserver2"]

BZ #106 2701

Previously, the ability to configure Compute Network to use other

types of network manager, specifically the VLAN manager were not

included with OpenStack Foreman Installer.

With this release, this enhancement has been added. As a result,

Compute Network is now fully configurable, so anything the

upstream puppet code allows can be done using the Foreman

hostgroup.

BZ #106 4 050

In the HA-all-in-one controller, file access for glance to shared

storage may be specified by the parameters: backend (must be

'file'), pcmk_fs_manage (must be 'true' for pacemaker to manage

the filesystem), pcmk_fs_device (the shared storage device),

pcmk_fs_options (any needed mount options).

For cinder, the relevant options are: volume_backend ('glusterfs'

or 'nfs'), glusterfs_shares (if using gluster), nfs_shares (if

using nfs), and nfs_mount_options (if using nfs).
