workers auto Override the number of pre-forked workers

should be an integer, zero means no fork. If

unset, it will try to default to the number

of effective cpu cores and fallback to one.

the :ref:`servers_per_port
|

<server-per-port-configuration>`
|
||||
option provides complete I/O isolation with
|
||||
no measurable overhead.
|
||||
servers_per_port 0 If each disk in each storage policy ring has
|
||||
unique port numbers for its "ip" value, you
|
||||
can use this setting to have each
|
||||
object-server worker only service requests
|
||||
for the single disk matching the port in the
|
||||
ring. The value of this setting determines
|
||||
how many worker processes run for each port
|
||||
(disk) in the ring. If you have 24 disks
|
||||
per server, and this setting is 4, then
|
||||
each storage node will have 1 + (24 * 4) =
|
||||
97 total object-server processes running.
|
||||
This gives complete I/O isolation, drastically
|
||||
reducing the impact of slow disks on storage
|
||||
node performance. The object-replicator and
|
||||
object-reconstructor need to see this setting
|
||||
too, so it must be in the [DEFAULT] section.
|
||||
See :ref:`server-per-port-configuration`.
|
||||
max_clients 1024 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.
|
||||
disable_fallocate false Disable "fast fail" fallocate checks if the
|
||||
underlying filesystem does not support it.
|
||||
log_max_line_length 0 Caps the length of log lines to the
|
||||
value given; no limit if set to 0, the

default.
|

log_custom_handlers None Comma-separated list of functions to call
|
||||
to setup custom log handlers.
|
||||
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.
|

conn_timeout 0.5 Time to wait while attempting to connect to
|
||||
another backend node.
|

node_timeout 3 Time to wait while sending each chunk of data

data from a client or another backend node.
