Find an example account server configuration at
etc/account-server.conf-sample in
the source code repository.
The available configuration options are:
| Configuration option = Default value | Description |
|---|---|
| bind_ip = 0.0.0.0 | IP Address for server to bind to |
| bind_port = 6002 | Port for server to bind to |
| bind_timeout = 30 | Seconds to attempt bind before giving up |
| backlog = 4096 | Maximum number of allowed pending TCP connections |
| user = swift | User to run as |
| swift_dir = /etc/swift | Swift configuration directory |
| devices = /srv/node | Parent directory of where devices are mounted |
| mount_check = true | Whether or not check if the devices are mounted to prevent accidentally writing to the root device |
| disable_fallocate = false | Disable "fast fail" fallocate checks if the underlying filesystem does not support it. |
| workers = auto | a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests. |
| max_clients = 1024 | Maximum number of clients one worker can process simultaneously Lowering the number of clients handled per worker, and raising the number of workers can lessen the impact that a CPU intensive, or blocking, request can have on other requests served by the same worker. If the maximum number of clients is set to one, then a given worker will not perform another call while processing, allowing other workers a chance to process it. |
| log_name = swift | Label used when logging |

| log_statsd_host = localhost | If not set, the StatsD feature is disabled. |
| log_statsd_port = 8125 | Port value for the StatsD server. |
| log_statsd_default_sample_rate = 1.0 | Defines the probability of sending a sample for any given event or timing measurement. |
| log_statsd_sample_rate_factor = 1.0 | Not recommended to set this to a value less than 1.0, if frequency of logging is too high, tune the log_statsd_default_sample_rate instead. |
| log_statsd_metric_prefix = | Value will be prepended to every metric sent to the StatsD server. |
| db_preallocation = off | 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. underlying filesystem does not support it. to setup custom log handlers. bytes you'd like fallocate to reserve, whether there is space for the given file size or not. This is useful for systems that behave badly when they completely run out of space; you can make the services pretend they're out of space early. server. For most cases, this should be `egg:swift#account`. replication passes account can be reclaimed |
| eventlet_debug = false | If true, turn on debug logging for eventlet |
| fallocate_reserve = 0 | 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. This is useful for systems that behave badly when they completely run out of space; you can make the services pretend they're out of space early. server. For most cases, this should be `egg:swift#object`. |

| delay_reaping = 0 | Normally, the reaper begins deleting account information for deleted accounts immediately; you can set this to delay its work however. The value is in seconds, 2592000 = 30 days, for example. bind to giving up 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. By increasing the number of workers to a much higher value, one can reduce the impact of slow file system operations in one request from negatively impacting other requests. |
