|
.B object-server.conf
|
|
|

.SH DESCRIPTION
|
|
.PP
|
|
This is the configuration file used by the object server and other object
|
|
background services, such as; replicator, reconstructor, updater, auditor, and
|
|
expirer.
|
|
|
|
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.
|
|
|

|
|
.IP "\fBauto_create_account_prefix [deprecated]\fR"

.IP "\fBreplication_server\fR"
|
|
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".
|
|
.IP "\fBreplication_concurrency\fR"

by the object reconstructor or the object replicator when configured to use ssync.
|
|
.IP "\fBreplication_concurrency_per_device\fR"

|
Set to restrict the number of concurrent incoming SSYNC requests per device;
|
|
set to 0 for unlimited requests per devices. This can help control I/O to each

device. This does not override replication_concurrency described above, so you

may need to adjust both parameters depending on your hardware or network
|
|
capacity. Defaults to 1.

|
.IP "\fBreplication_failure_ratio\fR"
|
|
These two settings control when the SSYNC subrequest handler will
|
|
abort an incoming SSYNC attempt. An abort will occur if there are at
|
|
least threshold number of failures and the value of failures / successes
|
|
exceeds the ratio. The defaults of 100 and 1.0 means that at least 100
|
|
failures have to occur and there have to be more failures than successes for
|
|
an abort to occur.
|
|
.IP "\fBsplice\fR"
|
|
Use splice() for zero-copy object GETs. This requires Linux kernel
|
|
version 3.0 or greater. If you set "splice = yes" but the kernel
|
|
does not support it, error messages will appear in the object server
|
|
logs at startup, but your object servers should continue to function.
|
|
The default is false.

|
|
Request timeout to external services. The default is 3 seconds.

|
|
are IOPRIO_CLASS_RT (realtime), IOPRIO_CLASS_BE (best-effort) and IOPRIO_CLASS_IDLE (idle).

standard profiler. Currently the supported value can be 'cProfile', 'eventlet.green.profile' etc.
|
|
.IP "\fBlog_filename_prefix\fR"
|
|
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).
|

it with an unique value like, the default is /var/log/swift/profile/account.profile.

|
|
in this interval. The default is 5.0.
|

.IP "\fBdump_timestamp\fR"
|
|
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.

as having performance comparable to, or better than, rsync, we plan to

.IP "\fBhandoffs_first\fR"
|
|
The flag to replicate handoffs prior to canonical partitions.
|
|
It allows one to force syncing and deleting handoffs quickly.
|
|
If set to a True value(e.g. "True" or "1"), partitions

|
that are not supposed to be on the node will be replicated first.
|
|
The default is false.
|
|
.IP "\fBhandoff_delete\fR"
|
|
The number of replicas which are ensured in swift.
|
|
If the number less than the number of replicas is set, object-replicator
|
|
could delete local handoffs even if all replicas are not ensured in the
|
|
cluster. Object-replicator would remove local handoff partition directories
|
|
after syncing partition when the number of successful responses is greater
|
|
than or equal to this number. By default(auto), handoff partitions will be
|
|
removed when it has successfully replicated to all the canonical nodes.
|
|
|
|
The handoffs_first and handoff_delete are options for a special case
|
|
such as disk full in the cluster. These two options SHOULD NOT BE
|
|
CHANGED, except for such an extreme situations. (e.g. disks filled up
|
|
or are about to fill up. Anyway, DO NOT let your drives fill up).
