Table 3 FSE server directory layout

NOTE: You can assign additional file systems or volumes to the FSE disk buffer. These file systems must be

mounted on subdirectories one level below the root directory of the FSE disk buffer. For details, see the FSE

user guide, chapter ”Monitoring and maintaining FSE”, section ”Extending storage space of FSE disk

buffer”.

IMPORTANT: To achieve a sufficient stability of the FSE disk media, a separate file system must be

dedicated for each disk medium, and it must be mounted to the corresponding subdirectory of the FSE disk

media directory. Thus, the FSE disk media directory itself does not need to be located on a separate file

system.

Estimating the size of file systems

Each of the previously mentioned file systems holds large databases and/or system files. Therefore, you

need to calculate the space requirement for all of them before they are created.

The sizes of the HSM file system, Fast Recovery Information (FRI) files, File System Catalog (FSC), and

Hierarchical Storage Manager Database (HSMDB) files are all related to several parameters. Among these

parameters are the number of files on an HSM file system and their average size.

By default, 32 MB of journal space is created on Ext3 file systems. This should be sufficient for the file

systems of the following directories:

• /var/opt/fse

• /var/opt/fse/part

• /var/opt/fse/diskbuf

Directory Contents File system type LVM volume

/var/opt/fse/ Configuration Database, Resource

Management Database, other
