Configure OpenStack Object Storage (Swift).
This example configures with the environment below.

Configure Storage Node in this section.
It's OK to set the same settings mostly on all Storage Nodes, but IP address and Device number are different, though. Furthermore, add Hard drives on each Storage Nodes and create a partition "/dev/sdb1" for this settings.
[1] Install Swift-Account, Swift-Container, Swift-Object.
# install from EPEL OpenStack, EPEL

[root@node01 ~]#
yum --enablerepo=openstack-havana,epel -y install openstack-swift-account openstack-swift-container openstack-swift-object xfsprogs xinetd rsync openssh-clients
[2] Format free space on disk (/dev/sdb1 on this example) with XFS and mount on /srv/node (the number "device*" is different on each Storage Nodes).
[root@node01 ~]#
mkfs.xfs -i size=1024 /dev/sdb1

meta-data=/dev/sdb1              isize=1024   agcount=4, agsize=6553514 blks
         =                       sectsz=512   attr=2, projid32bit=0
data     =                       bsize=4096   blocks=26214055, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0
log      =internal log           bsize=4096   blocks=12799, version=2
         =                       sectsz=512   sunit=0 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

[root@node01 ~]#
mkdir -p /srv/node/device0

[root@node01 ~]#
mount -o noatime,nodiratime,nobarrier /dev/sdb1 /srv/node/device0

[root@node01 ~]#
chown -R swift. /srv/node

[root@node01 ~]#
vi /etc/fstab
# add at the last

/dev/sdb1               /srv/node/device0       xfs     noatime,nodiratime,nobarrier 0 0
[3] Copy Swift Ring file from Swift Proxy Node to this Storage Node.
[root@proxy ~]#
scp /etc/swift/*.gz 10.0.0.51:/etc/swift/

The authenticity of host '10.0.0.51 (10.0.0.51)' can't be established.
RSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:f3:ed:54.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '10.0.0.51' (RSA) to the list of known hosts.
root@10.0.0.51's password:
account.ring.gz                            100% 3867     3.8KB/s   00:00
container.ring.gz                          100% 3899     3.8KB/s   00:00
object.ring.gz                             100% 3877     3.8KB/s   00:00
[4] Change owner for Swift Ring file.
[root@node01 ~]#
chown swift. /etc/swift/*.gz

[5] Configure Swift and Rsync.
