Run the below command to see Gluster mount point on any of the cfxDimensions platform VM. (Login as 'macaw' user using any SSH client to access the CLI)
The Gluster volume is configured to mount as /opt/macaw using the below mount options. Please refer /etc/fstab
defaults,backup-volfile-servers=192.168.186.152:192.168.186.153,_netdev,noauto,x-systemd.automount 0 0
backup-volfile-servers: This option is used by the Gluster client while mounting the volume, when the primary Gluster node is not available, it will try backup Gluster node to fetch the volume's metadata and complete the mount operation.
noauto & x-systemd.automount: 'noauto' option is used not to mount during boot-up time automatically. However, it is used along with x-systemd.automount option which enables to mount the Gluster volume automatically on access by client service. This is similar to AutoFS feature of NFS shares.
