=head2 allow_two_primaries
This enables dual-primary for the given resource. This is meant to be called prior to a live migration, and should be disabled again as soon as possible via C<< DRBD->reload_defaults >>.
Parameters;
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default 'root')
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 resource (required)
This is the name of the resource to enable two primaries on.
=head3 set_to (optional, default 'yes')
This can be set to C<< yes >> to allow two-primary, or C<< no >> to disable it.
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.
=head3 target_node_id (optional, but see condition below)
This is the DRBD target node's (connection) ID that we're enabling dual-primary with. If this is not passed, but C<< drbd::status::<local_short_host_name>::resource::<resource>::connection::<peer_name>::peer-node-id >> is set, it will be used. Otherwise this argument is required.

=head2 delete_resource
This method deletes an entire resource. It does this by looping through the volumes configured in a resource and deleting them one after the other (even if there is only one volume).
On success, C<< 0 >> is returned. If there are any issues, C<< !!error!! >> will be returned.
Parameters;
=head3 resource (required)
This is the name of the resource to be deleted.
=head3 wait (optional, default '1')
This controls whether we wait for a resource that is C<< Primary >> or C<< SyncSource >> to demote or the sync target to disconnect before proceeding. If whis is set to C<< 0 >>, instead of waiting, the method returns an error and aborts.

This calls C<< drbdadm >> to collect the configuration of the local system and parses it. This methid is designed for use by C<< scan_drbd >>, but is useful elsewhere. This is note-worthy as the data is stored under a C<< new::... >> hash.
On error, C<< 1 >> is returned. On success, C<< 0 >> is returned.
Parameters;
=head3 xml (optional)
If set to the XML generated by C<< drbdadm dump-xml >> elsewhere, this will be parsed instead of making the call.

=head2 get_devices
This finds all of the configured '/dev/drbdX' devices and maps them to their resource names.
Parameters;
=head3 anvil_uuid (optional)
If set, the C<< drbdadm dump-xml >> is not called, instead the most recent version as recorded in C<< scan_drbd -> scan_drbd_common_xml >> is loaded from one of the hosts.
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default 'root')
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.

=head2 get_next_resource
This returns the next free DRBD minor number and the next free TCP port. The minor number and TCP port returned are ones found to be free on both/all machines in Anvil! system. As such, the returned values may skip values free on any given system.
If a resource name is given, then the caller can either return an error if the name matches (useful for name conflict checks) or return the first (lowest) minor number and TCP used by the resource.
my ($free_minor, $free_port) = $anvil->DRBD->get_next_resource({anvil_uuid => "a5ae5242-e9d3-46c9-9ce8-306855aa56db"})
If there is a problem, two empty strings will be returned.
B<< Note >>: Deleted resources, volumes and peers are ignored! As such, a minor or TCP port that used to be used by deleted resource can be returned.
Parameters;
=head3 anvil_uuid (optional, default 'Cluster->get_anvil_uuid')
This is the Anvil! in which we're looking for the next free resources. It's required, but generally it doesn't need to be specified as we can find it via C<< Cluster->get_anvil_uuid() >>.
=head3 dr_tcp_ports (optional, default '0')
If set, the 'free_port' returned will be a comma-separated pair of TCP ports. This is meant to help find two TCP ports needed to connect a resource from both nodes to a DR host.
=head3 long_throw_ports (optional, default '0')
If set, the 'free_port' returned will be a comma-separated list of seven TCP ports needed for a full B<< Long Throw >> configuration.
=head3 minor_only (optional, default '0')
When set to C<< 1 >>, only a new minor number is returned. The tcp number will be an empty string.
=head3 resource_name (optional)
If this is set, and the resource is found to already exist, the first DRBD minor number and first used TCP port are returned. Alternatively, if C<< force_unique >> is set to C<< 1 >>, and the resource is found to exist, empty strings are returned.
=head3 force_unique (optional, default '0')
This can be used to cause this method to return an error if C<< resource_name >> is also set and the resource is found to already exist.

=head2 get_status
This parses the DRBD status on the local or remote system. The data collected is stored in the following hashes;
drbd::status::<host_name>::resource::<resource_name>::{ap-in-flight,congested,connection-state,peer-node-id,rs-in-flight}
drbd::status::<host_name>::resource::<resource_name>::connection::<peer_host_name>::volume::<volume>::{has-online-verify-details,has-sync-details,out-of-sync,peer-client,peer-disk-state,pending,percent-in-sync,received,replication-state,resync-suspended,sent,unacked}
If the volume is resyncing, these additional values will be set:
drbd::status::<host_name>::resource::<resource_name>::connection::<peer_host_name>::volume::<volume>::{db-dt MiB-s,db0-dt0 MiB-s,db1-dt1 MiB-s,estimated-seconds-to-finish,percent-resync-done,rs-db0-sectors,rs-db1-sectors,rs-dt-start-ms,rs-dt0-ms,rs-dt1-ms,rs-failed,rs-paused-ms,rs-same-csum,rs-total,want}
drbd::status::<host_name>::resource::<resource>::devices::volume::<volume>::{al-writes,bm-writes,client,disk-state,lower-pending,minor,quorum,read,size,upper-pending,written}
If any data for the host was stored in a previous call, it will be deleted before the new data is collected and stored.
Parameters;
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default 'root')
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.

=head2 manage_resource
This takes a task, C<< up >>, C<< down >>, C<< primary >>, or C<< secondary >> and a resource name and acts on the request.
This returns the return code from the C<< drbdadm >> call. If C<< 255 >> is returned, then we did not get the actual return code from C<< drbdadm >>.
B<NOTE>: This just makes the call, it doesn't wait or watch for the action to actually finish.
Parameters;
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default 'root')
=head3 resource (required)
This is the name of the resource being acted upon.
=head3 task (required)
This is the action to take. Valid tasks are: C<< up >>, C<< down >>, C<< primary >>, and C<< secondary >>.
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.

=head2 reload_defaults
This switches DRBD back to running using the values in the config files. Specifically, it calls C<< drbdadm adjust all >>.
The return code from the C<< drbdadm >> call is returned by this method.
Parameters;
=head3 password (optional)
This is the password to use when connecting to a remote machine. If not set, but C<< target >> is, an attempt to connect without a password will be made.
=head3 port (optional)
This is the TCP port to use when connecting to a remote machine. If not set, but C<< target >> is, C<< 22 >> will be used.
=head3 remote_user (optional, default 'root')
If C<< target >> is set, this will be the user we connect to the remote machine as.
=head3 resource (required)
This is the name of the resource to reload the default configuration for (ie: disable dual primary, pickup changes from the config file, etc)..
=head3 target (optional)
This is the IP or host name of the machine to read the version of. If this is not set, the local system's version is checked.

Parameters;
=head3 new_resource_uuid (optional)
If this is set to a UUID, and no existing UUID is found, this UUID will be added to the resource config file.
=head3 replace (optional, default 0)
If this is set along with C<< new_resource_uuid >> is also set, the UUID will replace an existing UUID if one is found. Otherwise, it's added like no UUID was found.
=head3 resource (required)
This is the name of resource whose UUID we're looking for.
=head3 resource_file (required)
This is the full path to the resource configuration file that the UUID will be read from, if possible.

=head2 update_global_common
This configures C<< global_common.conf >> on the local host. Returns C<< !!error!! >> if there is a problem, an empty string if no update was needed and a unified C<< diff >> of the changes made, if any.
Parameters;
=head3 usage_count (optional, default '1')
By default, DRBD will call a LINBIT server and add itself to a counter, and then reports back what install number this machine is. This helps LINBIT understand how DRBD is used, and no personal identifiable information is passed to them. If you would like to disable this, set this to C<< 0 >>.
=head3 use_flushes (optional, default '1')
Normally, when a write is done, a flush is called to ensure the data has been written from cache to disk. This is usually desired as it is safe, but does impose a performance penalty.
When there is a hardware RAID controller with protected write cache, explicit flushes can safely be turned off, gaining performance.
If ScanCore can detect a hardware RAID controller, this method will disable disk flushes automatically. This parameter can be used to force flushes on (C<< 1 >>) or off (C<< 0 >>).
B<< Note >>: ScanCore can not yet do this.

=head2 _initialize_kmod
This checks to see if the C<< drbd >> kernel module can load. If not, a check is made to see if an RPM that matches the kernel exists. If so, it is installed. If not, C<< akmods >> is asked to build and install the drbd kernel module.
Returns C<< 0 >> is the module loads or is already loaded. C<< !!error!! >> if not.
