Note
To verify the existence of the IP service resource used in a cluster service, you must use the
/sbin/ip addr list command on a cluster node. T he following output shows the /sbin/ip
addr list command executed on a node running a cluster service:
1: lo: <LOOPBACK,UP> mtu 16436 qdisc noqueue

3.10. Configuring Cluster Storage
To configure storage for a cluster, click the storage tab. Clicking that tab causes the display of the
Welcom e to Storage Configuration Interface page.
The st orage tab allows you to monitor and configure storage on remote systems. It provides a means
for configuring disk partitions, logical volumes (clustered and single system use), file system parameters,
and mount points. The storage tab provides an interface for setting up shared storage for clusters and
offers GFS and other file systems as file system options. When a you select the storage tab, the
Welcom e to Storage Configuration Interface page shows a list of systems available to the
you in a navigation table to the left. A small form allows you to choose a storage unit size to suit your
preference. T hat choice is persisted and can be changed at any time by returning to this page. In
addition, you can change the unit type on specific configuration forms throughout the storage user
interface. T his general choice allows you to avoid difficult decimal representations of storage size (for
example, if you know that most of your storage is measured in gigabytes, terabytes, or other more
familiar representations).
Additionally, the Welcome to Storage Configuration Interface page lists systems that you
are authorized to access, but currently are unable to administer because of a problem. Examples of
problems:
A computer is unreachable via the network.
A computer has been re-imaged and the luci server admin must re-authenticate with the ricci agent
on the computer.
A reason for the trouble is displayed if the storage user interface can determine it.
Only those computers that the user is privileged to administer is shown in the main navigation table. If
you have no permissions on any computers, a message is displayed.
After you select a computer to administer, a general properties page is displayed for the computer. T his
page is divided into three sections:
