32 Preparing file systems for FSE
3. To ensure that the file system is automatically mounted at system startup, add the appropriate entry to
the file system table in the file /etc/fstab. When adding the entry, note that the device name in the
first column corresponds to the device file that you retrieved in the previous step:
4. Manually mount the corresponding file system for the directory /var/opt/fse. You must use the
device (logical volume) name from your actual LVM configuration:
5. Create the four remaining directories:
FileSystemMountPoint should be a unique subdirectory name.
6. Invoke the following commands to retrieve the names of the device files. Use the symbolic links from the
step 1 of section ”Creating file systems on top of LVM logical volumes”:
7. Add the appropriate entries to the file system table in the file /etc/fstab. When adding the entries,
note that the device names in the first column correspond to the device files that you retrieved in the
previous step:
NOTE: The keyword data=journal must be specified in the fourth column in /etc/fstab for
correctly mounting the file system on the /var/opt/fse/part directory. This improves file system
stability and performance.
Note that all parameter entries must be entered in the proposed order.
NOTE: If you created an Ext2 file system for the FSE disk buffer, modify the fstab entry in the
above example accordingly.
