AIntegrating existing file systems in the FSE implementation

When the FSE is installed on a system where user files are located on already existing file systems, you may want to bring these files under FSE control. This is to make FSE aware of the already-existing files and include them in standard operations such as migration and recall.

The following procedure is for guidance only. Some of the steps are documented in the FSE user guide, chapter ”Configuring FSE”.

Integrating existing file systems

The following procedure summarizes the steps to convert the Ext2 file system (ext2 fs) to an HSM file system that stores user data in the FSE implementation. HSM file system is based on the Ext3 file system (ext3 fs).

If necessary, first convert the Ext2 file system to an Ext3 file system:

1.Unmount the existing file system.

2.Convert Ext2 file system to Ext3 using the command:

#tune2fs -jLogicalVolumeDevice

Example:

# tune2fs -j /dev/fse_sda/fs1

Configure a new FSE partition:

1.Prepare a new FSE partition configuration on the FSE server side.

2.Add this FSE partition to the FSE configuration.

Next, convert the Ext3 file system to an HSM file system:

3.If the Ext3 file system is still mounted, unmount it.

4.If needed, create a new mount point (new directory) for the HSM file system.

5.Mount the logical volume LogicalVolumeDevice that stores the Ext3 file system to the mount point as HSM file system.

6.If you created a new mount point in step 4, enable automatic mounting of the new HSM file system by adding its entry with appropriate options to the /etc/fstab file.

If you reused an existing mount point for mounting the HSM file system, modify its entry in the /etc/fstab file accordingly.

For details, see section ”Automating the mounting of HSM file systems” on page 49.

7.The final step is to make the FSE implementation aware of the existing directories and files. This needs to be done to introduce old directories and files to the FSE implementation and to add file attributes to the appropriate Hierarchical Storage Management Database (HSMDB).

Directories and files are introduced to the FSE by running a treewalk through all directories and opening each file on the HSM file system. To perform this process, invoke the following command from the HSM file system root directory:

HSMFileSystemRoot # find * -type f xargs -n1 head -n0

File System Extender (FSE) specifications

HP File System Extender (FSE) is a sophisticated solution designed to optimize data storage management for enterprises that deal with large volumes of unstructured data. This technology addresses the challenges of data growth and the need for effective data retention strategies, enabling organizations to store and manage their information more efficiently.

One of the main features of HP FSE is its ability to intelligently migrate data between primary and secondary storage. By utilizing policies that determine when to move infrequently accessed files to lower-cost storage environments, FSE helps reduce the strain on primary storage systems and saves on costs associated with high-performance storage solutions. This tiered approach to data management ensures that organizations can access the data they need quickly while still maintaining an efficient overall storage architecture.

Another notable characteristic of HP FSE is its seamless integration with existing storage infrastructures. The solution works with a variety of storage systems, allowing organizations to utilize their current investments without the need for significant changes to their infrastructure. This interoperability is powered by advanced technologies that facilitate data migration and retrieval, ensuring a smooth transition for organizations looking to optimize their storage strategies.

Additionally, HP FSE is equipped with robust reporting and analytics capabilities. This functionality provides organizations with insights into their storage usage, helping them understand data patterns and optimize their storage environments accordingly. By having visibility into which files are accessed most frequently and which are rarely used, organizations can make informed decisions on data retention policies and storage management.

Security is paramount in data management, and HP FSE addresses this concern by implementing advanced data protection features. This includes data encryption, secure access controls, and compliance with industry regulations, ensuring that sensitive information is safeguarded throughout its lifecycle.

Overall, HP File System Extender is a comprehensive data storage solution that combines intelligent data management, seamless integration, insightful analytics, and robust security features. By leveraging these capabilities, organizations can efficiently manage their unstructured data, lower costs, and enhance operational efficiency, making it an invaluable tool in today’s data-driven landscape.
