18.4.5. Configuring Object Server

The Object Server is a very simple blob storage server that can store, retrieve, and delete objects stored on local devices. Objects are stored as binary files on the file system with metadata stored in the file’s extended attributes (xattrs). This requires that the underlying file system choice for object servers support xattrs on files.
The configurable options pertaining to Object Server are stored in the file /etc/swift/object-server/1.conf. The following is the sample object-server/1.conf file:
[DEFAULT]
devices = /srv/1/node
mount_check = false
bind_port = 6010
user = root
log_facility = LOG_LOCAL2

[pipeline:main]
pipeline = gluster object-server

[app:object-server]
use = egg:swift#object 

[filter:gluster]
use = egg:swift#gluster

[object-replicator]
vm_test_mode = yes

[object-updater]
[object-auditor]
The following are the configurable options:
