NAME account-server.conf - configuration file for the openstack-swift account server SYNOPSIS account-server.conf DESCRIPTION This is the configuration file used by the account server and other account background services, such as; replicator, auditor and reaper. The configuration file follows the python-pastedeploy syntax. The file is divided into sections, which are enclosed by square brackets. Each section will contain a certain num‐ ber of key/value parameters which are described later. Any line that begins with a '#' symbol is ignored. You can find more information about python-pastedeploy configuration format at http://pythonpaste.org/deploy/#config-format GLOBAL SECTION This is indicated by section named [DEFAULT]. Below are the parameters that are acceptable within this section. bind_ip IP address the account server should bind to. The default is 0.0.0.0 which will make it bind to all available addresses. bind_port TCP port the account server should bind to. The default is 6002. bind_timeout Timeout to bind socket. The default is 30. backlog TCP backlog. Maximum number of allowed pending connections. The default value is 4096. workers The number of pre-forked processes that will accept connections. Zero means no fork. The default is auto which will make the server try to match the number of effective cpu cores if python multiprocessing is available (included with most python distributions >= 2.6) or fallback to one. It's worth noting that individual workers will use many eventlet co-routines to service multiple concurrent requests. max_clients Maximum number of clients one worker can process simultaneously (it will actually accept(2) N + 1). Setting this to one (1) will only handle one request at a time, without accepting another request concurrently. The default is 1024. user The system user that the account server will run as. The default is swift. swift_dir Swift configuration directory. The default is /etc/swift. devices Parent directory or where devices are mounted. Default is /srv/node. mount_check Whether or not check if the devices are mounted to prevent accidentally writing to the root device. The default is set to true. disable_fallocate Disable pre-allocate disk space for a file. The default is false. log_name Label used when logging. The default is swift. log_facility Syslog log facility. The default is LOG_LOCAL0. log_level Logging level. The default is INFO. log_address Logging address. The default is /dev/log. log_max_line_length The following caps the length of log lines to the value given; no limit if set to 0, the default. log_custom_handlers Comma separated list of functions to call to setup custom log handlers. functions get passed: conf, name, log_to_console, log_route, fmt, logger, adapted_logger. The default is empty. log_udp_host If set, log_udp_host will override log_address. log_udp_port UDP log port, the default is 514. log_statsd_host StatsD server. IPv4/IPv6 addresses and hostnames are supported. If a hostname resolves to an IPv4 and IPv6 address, the IPv4 address will be used. log_statsd_port The default is 8125. log_statsd_default_sample_rate The default is 1. log_statsd_sample_rate_factor The default is 1. log_statsd_metric_prefix The default is empty. db_preallocation If you don't mind the extra disk space usage in overhead, you can turn this on to preallocate disk space with SQLite databases to decrease fragmentation. The default is false. eventlet_debug Debug mode for eventlet library. The default is false. fallocate_reserve You can set fallocate_reserve to the number of bytes you'd like fallocate to reserve, whether there is space for the given file size or not. The default is 0. PIPELINE SECTION This is indicated by section name [pipeline:main]. Below are the parameters that are acceptable within this section. pipeline It is used when you need apply a number of filters. It is a list of filters ended by an application. The normal pipeline is "healthcheck recon account-server". APP SECTION This is indicated by section name [app:account-server]. Below are the parameters that are acceptable within this section. use Entry point for paste.deploy for the account server. This is the reference to the installed python egg. This is normally egg:swift#account. set log_name Label used when logging. The default is account-server. set log_facility Syslog log facility. The default is LOG_LOCAL0. set log_level Logging level. The default is INFO. set log_requests Enables request logging. The default is True. set log_address Logging address. The default is /dev/log. auto_create_account_prefix The default is ".". replication_server Configure parameter for creating specific server. To handle all verbs, including replication verbs, do not specify "replication_server" (this is the default). To only handle replication, set to a true value (e.g. "true" or "1"). To handle only non-replication verbs, set to "false". Unless you have a separate replication net‐ work, you should not specify any value for "replication_server". The default is empty. FILTER SECTION Any section that has its name prefixed by "filter:" indicates a filter section. Filters are used to specify configuration parameters for specific swift middlewares. Below are the filters available and respective acceptable parameters. [filter:healthcheck] use Entry point for paste.deploy for the healthcheck middleware. This is the refer‐ ence to the installed python egg. This is normally egg:swift#healthcheck. disable_path An optional filesystem path which, if present, will cause the healthcheck URL to return "503 Service Unavailable" with a body of "DISABLED BY FILE". [filter:recon] use Entry point for paste.deploy for the recon middleware. This is the reference to the installed python egg. This is normally egg:swift#recon. recon_cache_path The recon_cache_path simply sets the directory where stats for a few items will be stored. Depending on the method of deployment you may need to create this directory manually and ensure that swift has read/write. The default is /var/cache/swift. [filter:xprofile] use Entry point for paste.deploy for the xprofile middleware. This is the reference to the installed python egg. This is normally egg:swift#xprofile. profile_module This option enable you to switch profilers which should inherit from python standard profiler. Currently the supported value can be 'cProfile', 'event‐ let.green.profile' etc. log_filename_prefix This prefix will be used to combine process ID and timestamp to name the profile data file. Make sure the executing user has permission to write into this path (missing path segments will be created, if necessary). If you enable profiling in more than one type of daemon, you must override it with an unique value like, the default is /var/log/swift/profile/account.profile. dump_interval The profile data will be dumped to local disk based on above naming rule in this interval. The default is 5.0. dump_timestamp Be careful, this option will enable profiler to dump data into the file with time stamp which means there will be lots of files piled up in the directory. The default is false path This is the path of the URL to access the mini web UI. The default is __pro‐ file__. flush_at_shutdown Clear the data when the wsgi server shutdown. The default is false. unwind Unwind the iterator of applications. Default is false. ADDITIONAL SECTIONS The following sections are used by other swift-account services, such as replicator, audi‐ tor and reaper. [account-replicator] log_name Label used when logging. The default is account-replicator. log_facility Syslog log facility. The default is LOG_LOCAL0. log_level Logging level. The default is INFO. log_address Logging address. The default is /dev/log. per_diff Maximum number of database rows that will be sync'd in a single HTTP replication request. The default is 1000. max_diffs This caps how long the replicator will spend trying to sync a given database per pass so the other databases don't get starved. The default is 100. concurrency Number of replication workers to spawn. The default is 8. run_pause [deprecated] Time in seconds to wait between replication passes. The default is 30. interval Replaces run_pause with the more standard "interval", which means the replicator won't pause unless it takes less than the interval set. The default is 30. node_timeout Request timeout to external services. The default is 10 seconds. conn_timeout Connection timeout to external services. The default is 0.5 seconds. reclaim_age Time elapsed in seconds before an account can be reclaimed. The default is 604800 seconds. rsync_compress Allow rsync to compress data which is transmitted to destination node during sync. However, this is applicable only when destination node is in a different region than the local one. The default is false. rsync_module Format of the rysnc module where the replicator will send data. See etc/rsyncd.conf-sample for some usage examples. recon_cache_path Path to recon cache directory. The default is /var/cache/swift. [account-auditor] log_name Label used when logging. The default is account-auditor. log_facility Syslog log facility. The default is LOG_LOCAL0. log_level Logging level. The default is INFO. log_address Logging address. The default is /dev/log. interval Will audit, at most, 1 account per device per interval. The default is 1800 sec‐ onds. accounts_per_second Maximum accounts audited per second. Should be tuned according to individual system specs. 0 is unlimited. The default is 200. recon_cache_path Path to recon cache directory. The default is /var/cache/swift. [account-reaper] log_name Label used when logging. The default is account-reaper. log_facility Syslog log facility. The default is LOG_LOCAL0. log_level Logging level. The default is INFO. log_address Logging address. The default is /dev/log. concurrency Number of reaper workers to spawn. The default is 25. interval Minimum time for a pass to take. The default is 3600 seconds. node_timeout Request timeout to external services. The default is 10 seconds. conn_timeout Connection timeout to external services. The default is 0.5 seconds. delay_reaping Normally, the reaper begins deleting account information for deleted accounts immediately; you can set this to delay its work however. The value is in sec‐ onds. The default is 0. reap_warn_after If the account fails to be be reaped due to a persistent error, the account reaper will log a message such as: Account <name> has not been reaped since <date> You can search logs for this message if space is not being reclaimed after you delete account(s). Default is 2592000 seconds (30 days). This is in addition to any time requested by delay_reaping.
