The loopback device serves as a virtual disk to hold the Object Storage service data.

Procedure

  1. If you are logged out, log back in to the Object Storage service.
    1. Using SSH, log in to the VMware Integrated OpenStack manager.
    2. From the VMware Integrated OpenStack manager, use SSH to log in to the controller01 node.
    3. Switch to root user. 
      sudo su -
  2. Create the loopback device. 
    truncate -s 5GB /srv/swift-disk1
mkfs.xfs /srv/swift-disk1
truncate -s 5GB /srv/swift-disk2
mkfs.xfs /srv/swift-disk2
truncate -s 5GB /srv/swift-disk3
mkfs.xfs /srv/swift-disk3
  3. Modify the /etc/fstab table file. 
    /srv/swift-disk1 /srv/node/sdb xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0
/srv/swift-disk2 /srv/node/sdc xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0
/srv/swift-disk3 /srv/node/sdd xfs loop,noatime,nodiratime,nobarrier,logbufs=8 0 0
  4. Mount the loopback device. 
    mkdir -p /srv/node/sdb
mount /srv/node/sdb
mkdir -p /srv/node/sdc
mount /srv/node/sdc
mkdir -p /srv/node/sdd
mount /srv/node/sdd
chown -R swift:swift /srv/node

What to do next

You can now create the rsyncd.conf file to en able the rsync service. See Enable the rsync Service.
