With this new system, a 'primary_db' is chosen (first connected DB UUID when sorted) and only it does resyncs. Further, resyncs have been pulled from all tools except anvil-daemon. So with this new system, the chances of duplicate, simultaneous resyncs should be removed (hopefully for real this time).
* Database->check_agent_data() no longer calls a resync after loading a
schema.
* Removed the Database->coonnect() 'all' parameter
* The database used to read from is now always the same as the primary,
even if there is a local DB.
* Database->connect() 'check_for_resync' parameter can now be set to
'2', which means "check for resync _if_ I am primary", where '1' still
checks for resync no matter what.

* Created System->wait_on_dnf() which was plucked from anvil-daemon, and now also called in scancore and anvil-safe-start.
* Updated scancore and anvil-safe-start to check on start that DRBD's kernel module is available (and build if not).

* Updated Network->load_ips() to load extra information about the interfaces.
* Updated ocf:alteeve:server to not check libvirtd daemon state on server start.
* Updated scan-hardware to check for duplicate entries and purge if found.
* Updated scan-network to check for the 'default' virbr0 interface by checking if the config file exists instead of calling virsh.
* Updated scan-server to have better logging.
* Created the new (and incomplete) anvil-test-alerts tool
* Updated scancore to support --purge to pass to all agents and then exit.
* Updated ScanCore->call_scan_agents() to no longer use 'timeout' as it was causing issues with virsh calls.

* Updated Database->resync_databases() to never run on non-striker machines. On Strikers, before a resync, _age_out_data() is called to clear old data in long-off databases.
* Created System->check_memory() that is loosely based on anvil-check-memory, but checks to see if it's being controlled by a systemctl started daemon and, if so, reads the RAM in use from it's status output.

* Updated Cluster->parse_cib() to not require a database connection (part of the work to make ocf:alteeve:server run without a DB)
* WIP: Continuing work on the ocf:alteeve:server RA to run without database connections.
* Updated the scancore daemon to explcitely check that all scan agent schemas are loaded in all databases on startup. This is to resolve resync issues on rebuilt strikers that may not yet have some schemas loaded when a DB resync runs.

* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.
Signed-off-by: Digimer <digimer@alteeve.ca>
* Added a new parameter to Database->connect() called 'no_resync' that, if set, prevents a resync check being performed. Updated ->resync_databases() to find a uuid_column where the table name ends in 'ies' and the UUID column is 'y_uuid'. Updated ->resync_databases() to not fire on updated table age anymore, and to trigger only if the number of rows differ in a given table by more than 10.
* Updated Log->entry() to prefix a tool's name, when the new 'log::scan_agent' value is set. Also set this value in ScanCore->agent_startup(), to help differentiate log entries.
* Fixed a bug in scancore's main loop where it logged the sleep message at the start of the run.

* Created Cluster->check_stonith_config() that checks and, if needed, reconfigures a cluster's fencing (stonith) config.

* Created Cluster->get_fence_methods() that parses all fence methods out of a recorded CIB and stores the in a hash for a given host_uuid.
* Fixed a bug in ScanCore->post_scan_analysis_striker() where the short_host_name was not being stored correctly.
Signed-off-by: Digimer <digimer@alteeve.ca>
* 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.

* 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 scan-ipimitool so that on nodes and dr hosts, it only scans itself. On strikers, it scans all hosts found in active Anvil! systems with a host_ipmi entry. `
* For all agents, reduced log verbosity to not push too much noise into anvil.log while scancore is running in the background.

* Started work on Get->available_resources() that will take an 'anvil_uuid' and figure out what resources are still available for use by new servers or that can be added to existing servers.
* Fixed a bug in ScanCore->agent_startup() where tables weren't being generated properly from the agent's SQL file.
* Made Storage->change_mode() return silently if it's called without a mode being passed. This happens frequently and is harmless so it's not worth filling the logs with errors.
* Renamed the 'start_time' key to 'at_start' when recording files' MD5 sums in Storage->record_md5sums and ->check_md5sums.
* When we moved the directory scan logic out of the 'scancore' daemon and into 'Storage->scan_directory', the logic to record scan agent names in 'scancore::agent::<file>' was removed. This broke a few things and, so, it was restored when it was found that a file starts with 'scan-' and the directory matches the scancore agent directory.
* Moved the 'scancore' daemon's 'load_agent_strings' to 'Words'
* Updated Words->parse_banged_string() to look for variables in the format 'value=X:units=Y' and translate it properly.
* Fixed a bug in scan-ipmitool where discovered sensor INSERT SQL queries were queued, but not committed.
* Fixed a bug in scan-storcli where a while loop was broken, preventing execution.
* Fixed a bug in the 'scancore' daemon where it wouldn't exit if sums changed. Fixed a bug where alerts weren't being sent between loops. Fixed a bug where command-line log level wasn't surviving inside the main loop.

* Created Database->get_power() that loads data from the special 'power' table.
* Fixed a bug in calls to Network->ping() where some weren't formatted properly for receiving two string variables.
* Updated Database->get_anvils() to record the machine types when recording host information.
* Updated Database->get_hosts_info() to also load the 'host_ipmi' column.
* Updated Database->get_upses() to store the link to the 'power' -> 'power_uuid', when available.
* Created ScanCore->call_scan_agents() that does the work of actually calling scan agents, moving the logic out from the scancore daemon.
* Created ScanCore->check_power() that takes a host and the anvil it is in and returns if it's on batteries or not. If it is, the time on batteries and estimate hold-up time is returned. If not, the highest charge percentage is returned.
* Created ScanCore->post_scan_analysis() that is a wrapper for calling the new ->post_scan_analysis_dr(), ->post_scan_analysis_node() and ->post_scan_analysis_striker(). Of which, _dr and _node are still empty, but _striker is complete.
** ->post_scan_analysis_striker() is complete. It now boots a node after a power loss if the UPSes powering it are OK (at least one has mains power, and the main-powered UPS(es) have reached the minimum charge percentage). If it's thermal, IPMI is called and so long as at least one thermal sensor is found and it/they are all OK, it is booted. For now, M2's thermal reboot delay logic hasn't been replicated, as it added a lot of complexity and didn't prove practically useful.
* Created System->collect_ipmi_data() and moved 'scan_ipmitool's ipmitool call and parse into that method. This was done to allow ScanCore->post_scan_analysis_striker() to also call IPMI on a remote machine during thermal down events without reimplementing the logic.
* Updated scan-ipmitool to only record temperature data for data collected locally. Also renamed 'machine' variables and hash keys to 'host_name' to clarify what is being stored.
* Updated scancore to clear the 'system::stop_reason' variable.
* Added missing packages to striker-manage-install-target.

* Fixed a bug in Database->insert_or_update_power() where the check to see if 'power_ups_uuid' was passed in was reversed. Also fixed a bug where the convertion of the value to TRUE/FALSE for the old value wasn't being set correctly.
* Updated Server->get_definition() to only translate the host name to a uuid if the host uuid wasn't passed in. Added a sanity check on the UUID as well.
* Cleaned up how existing UPSes are displayed in Striker when managing UPSes. Also renamed the form's scan agents to match the real agent names.
* Fixed alert sorting in scan-apc-pdu.

* Updated Server->migrate_virsh() to set 'servers' -> 'server_state' to 'migrating' and clear it again once the migation completes. Also added support for cold (frozen) versus live migrations.
* Updated Cluster->parse_cib() to check if a server with the server_state set to 'migrating' isn't actually migrating anymore and, if not, to clear that state. This is needed as scan-server will blindly ignore/skip any migrating server, and if a migration call is interrupted, the state could get stuck.
* Updated the 'servers' database table (and associated Database methods) to add columns for;
** server_ram_in_use - tracking RAM used by a running server
** server_configured_ram - RAM allocated to a running server (used with the above to alert a user and track _currently_ available RAM)
** server_updated_by_user - To be set by Striker tools to indicate when the user made a change that needs to push out to nodes / running server.
** server_boot_time - Tracks the unixtime when the server booted (to track uptime even if the server migrates across nodes).
* Created Get->anvil_name_from_uuid() to easily convert an Anvil! UUID into a name. Also created ->host_uuid_from_name() to translate a host name into a host UUID.
* Created Server->get_runtime() that translates a server name into a process ID and then uses that to determine how long (in seconds) it has been running. This is used when a server transitions from 'shut off' to 'running' to determine exactly when the server booted (current time - runtime).
* Renamed all 'Server->parse_definition' calls that used 'from_memory' to 'from_virsh' to clarify the data source.
* Made scan-hardware smarter about RAM change alerts.
* Updated scancore to load agent strings on startup so that processing pending alerts works properly.

* Updated Alert->register to take a hash reference for message variables to simplify when a caller plans to log and register an alert at the same time.
* Updated Convert->bytes_to_human_readable() to name the 'size' variable used internally for 'bytes' to actually be 'bytes' for better consistency.
* Created multiple new Database methods;
** ->check_condition_age() is meant to be used by scan agents to see how long a given condition has been in play (ie: how long ago power was lost to a UPS or a sensor became unreadable).
** ->insert_or_update_health() handles recording data to the new 'health' table, used for determining ideal hosts for servers between nodes.
** ->insert_or_update_power() handles recording data to the new 'power' table, used for determining how power events are handled.
** ->insert_or_update_temperature() handles recording temperature data to the new 'temperature' table, used to determine how thermal events are handled.
* Got a lot more done on the scan-hardware scan agent. Only part left now is post-scan health processing.

* Added the anvil.conf option 'sys::privacy::strong' that controls if the Anvil! ever "calls home". Initially, this controls DRBD's usage flag.
* Updated DRBD->get_devices() to track resources by their 'by-res' names as well and by the normal '/dev/drbdX' devices.
* To mitigate https://bugzilla.redhat.com/show_bug.cgi?id=1868467, updated Get->bridges() to parse the normal (non-JSON) data if we get invalid JSON output.
* Updated anvil-join-anvil to not disable, and in fact enable, libvirtd on boot. With DRBD 9, the original fear of a user accidentally booting a VM that's running on the peer no longer is an issue. By enabling it and leaving it on, Striker dashboard users won't lose their virtual machine manager link unless the node powers off. Also enabled actually updating the job progress, completing this tool!

* Updated anvil-configure-host to reboot when finished to be certain network changes have taken effect. Also updated the handling of virsh bridges to delete the autostart symlinks if libvirtd daemon isn't running.
* Added some logic to anvil-daemon to call 'anvil-update-states' with the -v{1,3} flag depending on the active debug level.
