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 number 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 6202.
keep_idle
Value to set for socket TCP_KEEPIDLE. The default value is 600.
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 of 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

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 or percentage of disk space you'd like
fallocate to reserve, whether there is space for the given file size or not. Percentage will be
used if the value ends with a '%'. The default is 1%.
nice_priority
Modify scheduling priority of server processes. Niceness values range from -20 (most favorable to
the process) to 19 (least favorable to the process). The default does not modify priority.

(realtime), IOPRIO_CLASS_BE (best-effort) and IOPRIO_CLASS_IDLE (idle). The default does not
modify class and priority. Work only with ionice_priority.
ionice_priority
Modify I/O scheduling priority of server processes. I/O niceness priority is a number which goes
from 0 to 7. The higher the value, the lower the I/O priority of the process. Work only with
ionice_class. Ignored if IOPRIO_CLASS_IDLE is set.
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.

Enables request logging. The default is True.
set log_address
Logging address. The default is /dev/log.
auto_create_account_prefix [deprecated]
The default is ".". Should be configured in swift.conf instead.
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 network, you should not specify any value for
"replication_server". The default is empty.
nice_priority

the process) to 19 (least favorable to the process). The default does not modify priority.
ionice_class
Modify I/O scheduling class of server processes. I/O niceness class values are IOPRIO_CLASS_RT
(realtime), IOPRIO_CLASS_BE (best-effort) and IOPRIO_CLASS_IDLE (idle). The default does not
modify class and priority. Work only with ionice_priority.
ionice_priority
Modify I/O scheduling priority of server processes. I/O niceness priority is a number which goes
from 0 to 7. The higher the value, the lower the I/O priority of the process. Work only with
ionice_class. Ignored if IOPRIO_CLASS_IDLE is set.
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 reference 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', 'eventlet.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 __profile__.
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

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 rsync 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.

can set this to delay its work however. The value is in seconds. The default is 0. The sum of
this value and the container-updater interval should be less than the account-replicator
reclaim_age. This ensures that once the account-reaper has deleted a container there is
sufficient time for the container-updater to report to the account before the account DB is
removed.
reap_warn_after
If the account fails to 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.
