=head2 boot_server |
|
|
|
This uses pacemaker to boot a server. |
|
|
|
If there is a problem, C<< !!error!! >> is returned. |
|
|
|
Parameters; |
|
|
|
=head3 server (required) |
|
|
|
This is the name of the server to boot. |
|
|
|
=head3 node (optional) |
|
|
|
If set, a resource constraint is placed so that the server prefers one node over the other before it boots. |
|
|
|
B<< Note >>; The method relies on pacemaker to boot the node. As such, if for some reason it decides the server can not be booted on the preferred node, it may boot on the other node. As such, this parameter does not guarantee that the server will be booted on the target node! |
|
|
|
=head3 wait (optional, default '1') |
|
|
|
This controls whether the method waits for the server to actually boot up before returning. By default, it will go into a loop and check every 2 seconds to see if the server is still running. Once it's found to be running, the method returns. If this is set to C<< 0 >>, the method will return as soon as the request to shut down the server is issued. |

=head2 check_server_constraints |
|
|
|
This method checks to see if the peer node is offline, and the local node is only. If this is the case, the location constraints for servers are checked to ensure that they favour the current host. If not, the location constraint is updated. |
|
|
|
This is meant to be used to prevent servers from automatically migrating back to a node after it was fenced. |
|
|
|
This method takes no parameters. |

If the target host is not in an Anvil!, or there is no CIB recorded for the Anvi!, C<< 1 >> is returned. |

This takes an Anvil! UUID and returns with node is currently the "primary" node. That is to say, which node has the most servers running on it, by allocated RAM. For example, if node 1 has two servers, each with 8 GiB of RAN and node 2 has one VM with 32 GiB of RAM, node 2 will be considered primary as it would take longest to migrate servers off. |
|
|
|
If all is equal, node 1 is considered primary. If only one node is a cluster member, it is considered primary. If neither node is up, an empty string is returned. |

=head2 manage_fence_delay |
|
|
|
This method checks or sets the fence delay that controls which node survives in a network split. Generally, this is the node hosting servers, as ScanCore's C<< scan-cluster >> should set this based on where the servers are runn. |
|
|
|
If C<< set >> is given an invalid host name, or if this is called on a node that is not a cluster member, C<< !!error!! >> is returned. Otherwise, the node with the delay favouring it is returned. If, somehow, neither node has a delay, then an empty string is returned. |
|
|
|
B<< Note >>: This must run on a node in a cluster. |
|
|
|
Parameters; |
|
|
|
=head3 prefer (optional) |
|
|
|
If this is set to a node name, that node will have the fence delay set to favour it. Specifically, the first fence method on this node has the C<< delay="15" >> argument added to it. If a delay is found on any other method, it is removed. |

=head2 migrate_server |
|
|
|
This manipulates pacemaker's location constraints to trigger a pacemaker-controlled migration of one or more servers. |
|
|
|
This method works by confirming that the server is running and it not on the target C<< node >>. If the server is server indeed needs to be migrated, a location constraint is set to give preference to the target node. Optionally, this method can wait until the migration is complete. |
|
|
|
B<< Note >>: This method does not make the actual C<< virsh >> call! To perform a migration B<< OUTSIDE >> pacemaker, use C<< Server->migrate_virsh() >>. |
|
|
|
Parameters; |
|
|
|
=head3 server (required) |
|
|
|
This is the server to migrate. |
|
|
|
=head3 node (required) |
|
|
|
This is the name of the node to move the server to. |
|
|
|
=head3 wait (optional, default '1') |
|
|
|
This controls whether the method waits for the server to shut down before returning. By default, it will go into a loop and check every 2 seconds to see if the server is still running. Once it's found to be off, the method returns. If this is set to C<< 0 >>, the method will return as soon as the request to shut down the server is issued. |

=head2 parse_cib |
|
|
|
This reads in the CIB XML and parses it from a local or remote system. On success, it returns C<< 0 >>. On failure (ie: pcsd isn't running), returns C<< 1 >>. |
|
|
|
If you call this against a remote machine, the data will be loaded the same as if it had been run locally. As such, if this is used from a Striker, be mindful of if it was called on Node 1 or 2. |
|
|
|
Parameters; |
|
|
|
=head3 cib (optional) |
|
|
|
B<< Note >>: Generally this should not be used. |
|
|
|
By default, the CIB is read by calling C<< pcs cluster cib >>. However, this parameter can be used to pass in a CIB instead. If this is set, the live CIB is B<< NOT >> read. |
|
|
|
=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. |

|
|
|
This reads in the XML output of C<< crm_mon >> and parses it. On success, it returns C<< 0 >>. On failure (ie: pcsd isn't running), returns C<< 1 >>. |
|
|
|
B<< Note >>: At this time, this method only pulls out the host for running servers. More data may be parsed out at a future time. |
|
|
|
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. |
|
|
|
=head3 xml (optional) |
|
|
|
B<< Note >>: Generally this should not be used. |
|
|
|
By default, the C<< crm_mon --output-as=xml >> is read directly. However, this parameter can be used to pass in raw XML instead. If this is set, C<< crm_mon >> is B<< NOT >> invoked. |

=head2 parse_quorum |
|
|
|
This parses C<< corosync-quorumtool -s -p >> to check the status of quorum, as it is more reliable that the CIB's c<< have-quorum >> flag. This does not parse out per-node information. |
|
|
|
b<< Note >>: See c<< man corosync-quorumtool >> for details on what these values store. |
|
|
|
If the cluster is down, C<< 1 >> is returned. Otherwise, C<< 1 >> is returned. |
|
|
|
Data is stored as: |
|
quorum::expected-votes |
|
quorum::flags |
|
quorum::nodes |
|
quorum::quorate |
|
quorum::ring_id |
|
quorum::total-votes |

B<< Note >>: If C<< wait >> is set to C<< 0 >>, then C<< 0 >> is returned once the shutdown is requested, not when it's actually turned off. |

|
This controls whether the method waits for the server to shut down before returning. By default, it will go into a loop and check every 2 seconds to see if the server is still running. Once it's found to be off, the method returns. If this is set to C<< 0 >>, the method will return as soon as the request to shut down the server is issued. |

=head2 _set_server_constraint |

|
|
This is a private method used to set a preferencial location constraint for a server. It takes a server name and a preferred host node. It checks to see if a location constraint exists and, if so, which node is preferred. If it is not the requested node, the constraint is updated. If no constraint exists, it is created. |
|
|
|
Returns C<< !!error!! >> if there is a problem, C<< 0 >> otherwise |
