Configure OpenStack Object Storage (Swift).
This example is based on the environment like follows.

Configure Storage Node on this section.
It's OK to set the same settings mostly on all Storage Nodes, but only IP address are different each other.
For storage partition, it needs enough size of free area on disks to create new partitions.
[1] Install Swift-Account, Swift-Container, Swift-Object and others on all Storage Node like follows.
# install from Victoria, EPEL, powertools

[root@snode01 ~]#
dnf --enablerepo=centos-openstack-victoria,powertools,epel -y install openstack-swift-account openstack-swift-container openstack-swift-object openstack-selinux xfsprogs rsync rsync-daemon openssh-clients
[2] Format free space of disk ([/dev/sdb1] on this example) with XFS and mount on [/srv/node/device] on all Storage Node like follows.
[root@snode01 ~]#
mkfs.xfs -i size=1024 -s size=4096 /dev/sdb1

meta-data=/dev/vdb1              isize=1024   agcount=4, agsize=5242815 blks
         =                       sectsz=4096  attr=2, projid32bit=1
         =                       crc=1        finobt=1, sparse=1, rmapbt=0
         =                       reflink=1
data     =                       bsize=4096   blocks=20971259, imaxpct=25
         =                       sunit=0      swidth=0 blks
naming   =version 2              bsize=4096   ascii-ci=0, ftype=1
log      =internal log           bsize=4096   blocks=10239, version=2
         =                       sectsz=4096  sunit=1 blks, lazy-count=1
realtime =none                   extsz=4096   blocks=0, rtextents=0

[root@snode01 ~]#
mkdir -p /srv/node/device

[root@snode01 ~]#
mount -o noatime,nodiratime /dev/sdb1 /srv/node/device

[root@snode01 ~]#
chown -R swift. /srv/node

[root@snode01 ~]#
vi /etc/fstab
# add to the end

/dev/sdb1               /srv/node/device       xfs     noatime,nodiratime 0 0
[3] Copy Swift Ring files from the Swift Proxy Node to all Storage Nodes.
[root@proxy ~]#
scp /etc/swift/*.gz 10.0.0.71:/etc/swift/

account.ring.gz                    100% 3912     3.8KB/s   00:00
container.ring.gz                  100% 3904     3.8KB/s   00:00
object.ring.gz                     100% 3895     3.8KB/s   00:00
[4] Configure Swift and Rsync on all Storage Nodes.
[root@snode01 ~]#
chown swift. /etc/swift/*.gz

[root@snode01 ~]#
vi /etc/swift/swift.conf
# set the value which is set on Proxy Node

[swift-hash]
swift_hash_path_suffix =
swift_shared_path
swift_hash_path_prefix = swift_shared_path
[root@snode01 ~]#
vi /etc/swift/account-server.conf
# line 6: change

bind_ip =
0.0.0.0

bind_port = 6202
[root@snode01 ~]#
vi /etc/swift/container-server.conf
# line 6: change

bind_ip =
0.0.0.0

bind_port = 6201
[root@snode01 ~]#
vi /etc/swift/object-server.conf
# line 6: change

bind_ip =
0.0.0.0

bind_port = 6200
[root@snode01 ~]#
vi /etc/rsyncd.conf
# add to the end

pid file = /var/run/rsyncd.pid
log file = /var/log/rsyncd.log
uid = swift
gid = swift
# specify the IP address of each storage node
address = 10.0.0.71

[account]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/account.lock

[container]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/container.lock

[object]
path            = /srv/node
read only       = false
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 25
lock file =     /var/lock/object.lock

[swift_server]
path            = /etc/swift
read only       = true
write only      = no
list            = yes
incoming chmod  = 0644
outgoing chmod  = 0644
max connections = 5
lock file =     /var/lock/swift_server.lock
[5] On Storage Node, if SELinux is enabled, change policy like follows.
[root@snode01 ~]#
semanage fcontext -a -t swift_data_t /srv/node/device

[root@snode01 ~]#
restorecon /srv/node/device
[6] On Storage Node, if Firewalld is running, allow service ports.
[root@snode01 ~]#
firewall-cmd --add-port={873/tcp,6200/tcp,6201/tcp,6202/tcp} --permanent

success
[root@snode01 ~]#
firewall-cmd --reload

success
[7] Start Swift services.
[root@snode01 ~]#
systemctl enable --now rsyncd \

openstack-swift-account-replicator \
openstack-swift-account \
openstack-swift-container-auditor \
