b8bb7cc423 * Changed the default trigger of live migrations to require a health score difference of 2 or higher. This can be user-adjusted using the new 'feature::scancore::threshold::preventative-live-migration' anvil.conf option.

bce9e2caaf This is the first attempt at enabling firewalld completely. There is a decent chance that problems exist, so it won't be a surprise if a few more commits are needed to this branch before things work.
* 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.

3fd0db15bf * This rather heavily reworks how database shutdowns works. It adds much more intelligent shutdown, tracking who is using the database, being able to mark a database as "offline" and waiting for users of the database to disconnect before it shuts down.
* Also removed the variables for the database name and DB user name, setting them statically now.
* Created Database->shutdown() to more kindly stop a local database server.
* Added 'check_db_in_use_states()' to anvil-daemon to clean any stale entries marking a database as in use.

72b17ff1f9 * Reworked how databases are stopped, now being handled in anvil-daemon. This way, initial starts will still do traditional resyncs, then shut down. This should allow the best of both worlds, where data is not lost on striker start/stop loss/recovery, but operate normally otherwise without delays.
* Updated Database->archive_database() to return the full path to the dump file.
* Disabled enabling the postgresql daemon.

922899ea78 * WIP: Working on a new method of failing over between which Striker is the active database, instead of running N-number of databases all the time.
* Created Database->backup_database() that creates a pg_dump of the active database.
* Created Database->load_database() that loads the database from a flat file, optionally creating a backup before doing so, and using iptables to block access during the process.
* Updated Database->configure_pgsql() to not start the postgresql daemon unless it just initialized the DB.
* Much work, not yet complete, to Database->connect() to stop after the first successful connection. Added logic that, if not connection was established and the host is a Striker, to load a peer's backup, if it exists, and then start the local daemon.
* Updated anvil-daemon to now have a section to run tasks on a ten minute cycle, which will later be used for the primary Striker to dump / copy its database to peer(s).

11b1900e1b Note: Continuing to resolve the build issues with network startup. Expect breakage.
* Upped the aging of jobs and alerts data from 2 to 24 hours. Also added a check to prevent deleting a job of any age that is incomplete.
* Major update to anvil-configure-host to not touch the network unless something has actually changed. Not yet tested on a fresh system, will verify nothing broke in the CI tests this commit will trigger. Also changed it so that, if after reconfiguring the network it times out trying to reconnect to a database, it calls a reboot instead of simply exiting. Further, a reboot is now not called on exit unless something changed to require it.
* Updated Network->check_bonds() to return '1' if anything was done to heal a bond.
* Updated anvil-update-states to be more careful about clearing virsh bridges. Specifically, it checks to see if virsh is running and that the returned bridges aren't actually error codes.

4dcd505753 * Biggest change in this commit; scan-apc-pdu and scan-apc-ups now only run on Striker dashboards! This was because we found that if two machines ran their agents at the same time, the reponce time from SNMP read requests grew a lot. This meant it was likely a third, fourth and so on machne would also then have their scan agent runs while the existing runs were still trying to process, causing the SNMP reads to get slower still until timeouts popped.
* Bumped scancore's scan delay from 30 seconds to 60.
* Shorted the age-out time to 24 hours and again boosted the archive thresholds. As we get a feel for the amount of data collected on multi-Anvil! systems over time, we may continue to tune this.l
* Moved Database->archive_database() to be called daily by anvil-daemon, instead of during '->connect' calls.
* Added locking to Database->_age_out_data to avoid resyncs mid-purge. Also moved the power, temperature and ip_address columns into the same 'to_clean' hash as it was duplicate logic.

6abe06f125 The theme of these commits is improving DB responsiveness.
* Created Database->_age_out_data() to delete records from the database that are old enough to no longer be useful. This is designed to significantly reduce the size of the database, allowing a better focus on performance.
* Changed Database->connect() to default to NOT check for resync, reworking the old 'no_resync' to 'check_for_resync', so that resync checks happen on demard, instead of by default.
* Updated get_tables_from_schema() to now allow 'schema_file' to be set to 'all', which then loads the schema files of all scan agents as well as the core anvil schema file. Fixed a bug where commented out tables were being counted.
* Re-enabled triggering resyncs on 'last_updated' differences.
* Fixed a bug in scan-ipmitool where the history_id column in history.scan_ipmitool_value was incorrect.
* Created a new tool called striker-show-db-counts that shows the number of records in all public and history schema tables for all databases.
* Updated anvil-update-states to detect when a libvirtd NAT'ed bridge exists and to delete it when found.

* 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.

ca7052dd53 The core logic is done!!!! Still need to finish end-points for the WebUI to hook into, but the core of M3 is complete! Many, many bugs are expected, of course. :)
* 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.

fb0836f912 * THe get_cpu endpoint was completed.
* 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.

413a4f73c2 * Updated Tools->_anvil_version() and Get->anvil_version() to now pick up a SchemaVersion from anvil.sql. This will change only when the schema changes and is used when Database->connect() is checking compatibility with other anvil database hosts. This will make it only break connection when there is a reason to do so. The anvil_version still remains as an informational version that will help when supporting users later.
* Updated Cluster->add_server() to now set failure timeouts to actual numbers instead of INFINITY after discovering that INFINITY doesn't work in those cases.
* Updated Databsae->get_hosts to now check if other entries have the same host name, and if so, to set their host_key to 'DELETED'. This should make it easier to handle when a hardware machine is replaced by new hardware but uses the same host_name.
* Updated Email->check_queue() to start and enable postfix.service if it's found to not be running.
* Updated Get->available_resources() to return '!!no_data!!' when a given host hasn't got any data in scan_lvm_vgs. Now use this in anvil-provision-server to exit if a node or dr host hasn't run scancore yet.
* Fixed a bug in scan-lvm where the pvs_uuid wasn't being loaded properly, preventing lost PVs, VGs and LVs from being flagged as deleted.
* Started work on anvil-migate-server, though it's far from complete.

89dec8e1f9 * Finished anvil-delete-server! (More testing needed though)
* Fixed a bug in Cluster->shutdown_server() where the wrong variable was being evaluated when checking the server state.
* Created DRBD->delete_resource() that deletes a resource's backing device and configuration. Note that this wipes the DRBD MD and and FS signatures before removing the LV. Updated DRBD->gather_data() to record the backing devices for volumes.

549dbad635 * Created Cluster->delete_server(), which deletes a server resource from pacemaker (stopping it first, if needed).
* Fixed a bug in Cluster->parse_cib() when a server that is off wasn't setting 'status'.
* Renamed 'server::location::<server>::host' to '...::host_name' in several places.
* Got more work done on anvil-delete-server, up to the point where it calls the new Cluster->delete_server() method.
* Updated fence_pacemaker to call 'drbdadm adjust all' to dampen an issue where in-memory fence configs seem to change, preventing reconnection of the peer after it reboots from the fence. More testing needed on this issue.
