When you have finished editing the /etc/sfstab.proto file on the head node, proceed to

Section 2.2.8 to prepare to image and configure the HP XC system.

2.2.8 Step 8: Preparing to image and configure the HP XC system

When the SFS service is started, it creates a local /etc/sfstab file from the /etc/sfstab.proto file.

To ensure correct operation of the imaging process, the /etc/sfstab file must exist before you run the

cluster_config utility.

Create an /etc/sfstab file on the head node by entering the following command:

# service sfs gensfstab

Proceed to Section 2.2.9 to mount the Lustre file systems.

2.2.9 Step 9: Mounting the Lustre file systems

To mount the Lustre file systems specified in the /etc/sfstab.proto file, enter the following command:

# service sfs start

When the command completes, all of the file systems specified in the /etc/sfstab.proto file will be

mounted. You can confirm this by entering the mount(8) command with no arguments. (Do not use the df(1)

command—it will hang if there is a connection problem with any component of a Lustre file system. If

commands such as df(1) hang, you can identify the connection that has failed using the sfslstate(8)

command. More details of using the sfslstate(8) command are provided in Section 4.10.1.)

When all of the file systems have mounted, proceed to Section 2.2.10 if quotas are to be used; otherwise,

proceed to Section 2.2.11.

2.2.10 Step 10: Enabling quotas functionality (optional)

If you plan to use quotas, follow the instructions provided in Chapter 5 of the HP StorageWorks Scalable

File Share System User Guide to configure the head node and the mount options in the

/etc/sfstab.proto file.

2.2.11 Step 11: Completing the installation of the HP XC system

When you have completed Steps 1 through 10 (in Section 2.2.1 through Section 2.2.10), return to the

HP XC System Software Installation Guide and continue with the installation of the HP XC system. As part

of the installation, the HP SFS configuration on the head node will be propagated to all other nodes in the

HP XC system.
