This section describes how to install and configure storage nodes that operate the account, container, and object services. For simplicity, this configuration references two storage nodes, each containing three empty local block storage devices. The instructions use /dev/sdb , /dev/sdc and /dev/sdd, but you can substitute different values for your particular nodes.
Prepare storage node3 and node4 as shown below:
Create mount point directory and moun:
$mkdir /srv/node/sdb /srv/node/sdc /srv/node/sdd $mount -a
Install the supporting utility packages:
$yum install xfsprogs rsync $vi /etc/rsyncd.conf
Create or edit rsyncd.conf file as shown below. — Replace the ip address with your storage nodes IP.
$systemctl enable rsyncd.service $systemctl start rsyncd.service
