* Did more work on adding support for adding new disk drives to servers in anvil-manage-server-storage.
* Updated anvil-manage-storage-groups To check for / delete duplicate storage groups with the same name.

* Fixed a small logging bug in DRBD->allow_two_primaries().
* Updated Database->get_jobs() to record jobs sorted by modified_date so that jobs can be run in the order they were recorded.
* Updated anvil-daemon to track which commands need to be run, and when two or more of the same command need to be run, they're run serially, with each subsequent run starting after the previous one completes.

* Updated DRBD->manage_resource() to set allow-two-primaries=no when up'ing a resource (as no migration can be in progress during an up command).
* Updated scan-drbd to look for StandAlone resources and call DRBD->manage_resource({task = 'up'}) if a connection to a peer node is StandAlone or if the local disk state is detached.

* Updated DRBD->delete_resource() to call scan-drbd and scan-lvm to ensure that the database is updated with the newly freed resources.
* Updated anvil-delete-server and anvil-provision-server to call select scan agents to ensure freed resources are immediately recorded.

* Updated DRBD->get_status() to attempt to recompile the drbd kernel module if the drbdsetup status fails. If it continues to fail, it exits gracefully now.
* Updated ocf:alteeve:server to test access over a given IP before calling Server->find to avoid timeouts when the peer is down. Also updated it to set the constraints to keep the server on the new host when the old host returns to the cluster.
* Fixed a bug in scan-cluster where a server that is FAILED but not running is now properly recovered.
Signed-off-by: digimer <mkelly@alteeve.ca>
* In DRBD->get_next_resource(), implemented a "hold" system where the DRBD minor and TCP port(s) returned are marked as being held for one minute. So subsequent calls won't use the same numbers.
* In anvil-daemon, added a check in run_jobs() where only one instance of a given job command will be started per 2-second loop. This should help reduce the chance of simultaneous race confitions in general.
* Removed from anvil-provision-server and most other tools the call to Job->get_job_uuid(). If the program is called without the job_uuid, don't try to find it. This allows a human (or script) to make repeated calls to a program without one of those calls running a pending job instead.

* Created DRBD->parse_resource() to pass a specific DRBD resource's XML data.
* Fixed a bug in Get->available_resources() so that if the threads is lower than CPU cores, the cores are used as the total available to VMs.
* Fixed bugs in Get->server_from_switch() where it just wasn't working properly.
* Updated scan_drbd to not reset a resource's size to 0-bytes when a resource goes offline.

* Created DRBD->check_proxy_license() to do (some level of) sanity checks on the DRBD proxy license file.
* Updated DRBD->gather_data() to parse out the inside and outside ports for resource configs using proxy.
* Reworked DRBD->get_next_resource() to return 1, 3 or 7 TCP ports depending, with the new long_throw_ports parameter triggering the 7 ports.
* Added 'tcpdump' to the anvil-core requires list.
* Reworked scan-drbd to record the ports used in proxy configs. This required adding a check to change the 'scan_drbd_peer_tcp_port' column type to 'text' to support CSVs.
* Reworked anvil-manage-dr (needs testing!) to support "long-throw" DR configs.
* Updated anvil-safe-stop to check if the nodes are in the cluster before trying to migrate.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Added multiple new private methods to Network that help in managing the firewall.
* Updated Server->boot_server to manage the firewall after the server boots. Updated ->migrate_server to create a job, if a database connection exists, for the migration target to update it's firewall as soon after the server appears as possible.
* Updated ocf:server:alteeve to manage the firewall when called post-migration, in case there was no DB connection and the job above didn't run. Fixed a bug where the disk state wasn't being evaluated properly.
* Updated scan-server to check that the firewall is managed when a server state has changed.
* Updated anvil-daemon to run Network->manage_firewall on startup.
* Heavily reworked 'anvil-manage-server' to either just run 'Network->manage_firewall', or if passed '--server X', to wait for the server to appear for up to 1 minute, then to check that the firewall is managed (to capture servers being migrated to the host.)
* Removed firewall management from striker-prep-database.

* Updated DRBD->allow_two_primaries() to take the 'set_to' parameter which can be 'yes' to all and 'no' to disallow dual-primary.

* DRBD is now configured to a ping-timeout of 3 seconds.
* Created Log->switches() that returnes the command line switches used by Anvil! tool command line calls based on the active log levels / secure logging. Appended this to all invocations of our tools.
* Updated Database->resync_databases() to now only skip 'jobs' and 'variables' tables with less than 10 record differences. All other differences will trigger a resync.
* Created System->_check_anvil_conf() that, as you might guess, checks in anvil.conf exists and created it (using defaults), if not. It also checks to see if the 'admin' group and user exists and creates them, if not.
* Updated anvil-daemon to check anvil.conf on start up and in each loop. Created the function check_journald() that checks (and sets, if needed) that journald logging is persistent.
* Made striker-manage-peers to check_if_configured on the Database->connect() when updating anvil.conf and the target UUID is the local machine. Also created a loop to make the reconnection a lot more robust.

* Created DRBD->check_if_syncsource() and ->check_if_synctarget() that return '1' if the target host is currently SyncSource or SyncTarget for any resource, respectively.
* Updated DRBD->update_global_common() to return the unified-format diff if any changes were made to global-common.conf.
* Created ScanCore->check_health() that returns the health score for a host. Created ->count_servers() that returns the number of servers on a host, how much RAM is used by those servers and, if available, the estimated migration time of the servers. Updated ->check_temperature() to set/clear/return the time that a host has been in a warning or critical temperature state.
* Finished ScanCore->post_scan_analysis_node()!!! It certainly has bugs, and much testing is needed, but the logic is all in place! Oh what a slog that was... It should be far more intelligent than M2 though, once flushed out and tested.
* Created Server->active_migrations() that returns '1' if any servers are in a migration on an Anvil! system. Updated ->migrate_virsh() to record how long a migration took in the "server::migration_duration" variable, which is averaged by ScanCore->count_servers() to estimate migration times.
* Updated scan-drbd to check/update the global-common.conf file's config at the end of a scan.
* Updated ScanCore itself to not scan when in maintenance mode. Also updated it to call 'anvil-safe-start' when ScanCore starts, so long as it is within ten minutes of the host booting.

* Added the scan-hpacucli scan agent. It's been done for a while and should have been added ages ago.
* Updated anvil-rename-server to get to the point where it will take down the DRBD resources on all machines, but waits if there is a sync under way. It also verifies that the server is off on all systems from virsh's perspective.

* The get_mmeory endpoint was completed.
* The get_replicated_storage endpoint was completed, though it requires testing and likely has issues.
To prepare for the get_status endpoint work, I needed to update ScanCore and modules to track the host_status. This commit contains the work needed for this.
* Updated ScanCore->post_scan_analysis_striker() to use configured fence devices (except PDUs) to check if a target host is off or on, in there is no host_ipmi interface. In all cases, if a machine can be confirmed on or off, the host_status is now updated.
* To support the above fence based power checks, updated scan-cluster to store the on-disk CIB in the new scan_cluster -> scan_cluster_cib colume.
* Updated ScanCore->parse_cib() to map stonith primitive IDs to fence agents. Updated ->parse_crm_mon() to not call if the executable doesn't exist to avoid unhelpful error messages in the logs when called from a Striker.
* Update DRBD->gather_data() to get the size data from /sys/block/drbd<minor>/size' x '/sys/block/drbd<minor>/queue/logical_block_size so it works when a device is Secondary (and can't be promoted).
* Updated Database->get_hosts_info() to record the short host name as well as the stored host name. Created ->update_host_status() as a wrapper to ->insert_or_update_hosts() that only updates the host status.
* Updated anvil-join-anvil to disabled ksm and ksmtuned daemons.
* Updated scancore and anvil-daemon to set the host_status to 'online' on startup.

* Fixed a bug in ScanCore->agent_startup() where a (thankfully broken) check to append tables to the 'sys::database::check_tables' would cause an infinite loop as both were pointers to the same anonymous array.
* Fixed a bug in scan-ipmitool where the scan_ipmitool_variables table didn't use a host_uuid reference, causing resyncs of that table to sync for all hosts and cause DB errors when the scan_ipmitool record from another host wasn't sync'ed yet.

* Reworked DRBD->get_next_resource() to pull from the database, and to no longer do that increments-of-three nonsense. Avoidable complexity. Also added a call to Cluster->get_anvil_uuid() if the 'anvil_uuid' parameter wasn't passed.
* Updated Database->get_host_from_uuid() and ->get_hosts() to now take 'include_deleted' parameter and default to not returning deleted hosts. This fixed issues where anvil-{delete,provision}-server calls could assign jobs to now-deleted hosts with reused host names.
* Updated anvil-delete-server to print log entries to STDOUT. Also updated it to not wait of shutdown of a server in pacemaker to complete, and instead to destroy it after calling pacemaker's resource stop. Updated to also check to see if the server being deleted is already out of pacemaker and, if so, skip that step and directly try to destroy the server, if it's running.
* Updated anvil-provision-server to force 'peer_mode' runs to pull their TCP Port and DRBD minor numbers from the job. This fixes a bug where the same resource on two machines could use different TCP ports.

* Finished DRBD->get_next_resource() that returns the next available minor and the next free TCP port (with two free ports available after it).
* Created Storage->get_storage_group_details() that pulls together the LVM, storage group members and storage groups into one block of data.
* Made more progress on tools/anvil-provision-server. It now gets up to the point of creating LVs, creating DRBD resource files, loading them, creating metadata and up'ing the resource. It doesn't yet (successfully) force a new resource to primary.
