Move shared disk presence logic from nodes into shared disk code

2014-07-02T04:17:18+00:00

Currently this is distributed around the node logic and is hard to
manage.

Instead, introduce 2 new functions (well, meta-functions, called using
call_func):

* is_dedicated_storage_node()

  Defaults to false.  Is true for sofs_storage.

* node_has_shared_disks()

  Defaults to false.  True for sofs_storage.  True for sofs_front when
  there are no dedicated storage nodes.

New configuration variable NETWORKS - IPBASE, IPNET* no longer used

2013-03-05T04:07:36+00:00

Much more flexible network configuration.

Replace canned host_setup/etc/libvirt/qemu/networks/*.xml with
setup_networks.sh script.

Explicitly set disk image type to $SYSTEM_DISK_FORMAT in node.xml.

2011-02-10T05:04:31+00:00

If you don't specify a type then RHEL6's KVM default it to 'raw'.

Make the disk cache types configurable.

2010-02-25T02:13:23+00:00

New options SYSTEM_DISK_CACHE and SHARED_DISK_CACHE can be used to
configure the cache type of the disks.  Valid values are: default,
none, writeback, writethrough - or as specified in the libvirt XML
documentation.

Split DISK_TYPE into SYSTEM_DISK_TYPE and SHARED_DISK_TYPE. DISK_PREFIX too.

2009-08-17T05:16:38+00:00

This allows IDE to be used for system disks and some other type,
perhaps virtio, to be used for the shared disks.  I seem to be seeing
some corruption issues with the combination of qcow2 and virtio, so
this will allow me to experiment with the raw shared disks and virtio.

When forcing writeback caching don't specify the image type.

2009-08-13T10:32:23+00:00

libvirt 0.6.1-0ubuntu5.1 tries to pass a "fmt" option instead of a
"format" option and kvm barfs.  It seems fine without the image type.

Force writeback caching on qcow2 disk images.

2009-08-13T03:41:38+00:00

Some versions of kvm disable all caching on qcow2 disk images to
guarantee data integrity on host failure.  We need caching to get
decent performance so we enable writeback caching by default.

Parameterise disk type and the corresponding device file prefix.

2009-08-13T03:36:43+00:00

The version of kvm under RHEL5.4 does not support the SCSI emulation.
So allow the use of ide or virtio instead.

New -e option for debugging.

2009-04-20T23:45:36+00:00

The new -e option accepts a bash expression, which is evaluated and
then autocluster exits.  This option is like --dump in that it can be
given only once because it triggers an immediate exit.  The -e option
is most useful for debugging template substitution - see the example
in README.

Remove extra variable NODEMEM from create_node() and node.xml - just
use MEM instead.  The body of create_node() is now in a subshell to
contain changes to MEM.
