Description

After formatting an FSE partition, the FSE partition is not mounted and HSM does not start.

 

(Windows system specific)

Explanation

This happens because formatting remounts the volume and the file system filter cannot attach to

 

it. You need to unmount the partition first and only then mount it.

Workaround

To mount the FSE partition, proceed as follows:

 

1.

Unmount the FSE partition on a client using fse --umount.

 

2.

On the FSE server, disable the FSE partition using the command:

 

 

fsepartition --disable PartitionName

 

 

Instead of disabling it, you can also remove it by running:

 

 

fsepartition --remove PartitionName

 

3.

Format FSE partition on client using Disk Management (select Start > Settings > Control

 

 

Panel, double-click Administrative Tools > Computer Management, in the Computer

 

 

Management GUI, select Storage > Disk Management, right-click the belonging volume

 

 

and select Format).

 

4.

On the FSE server, depending on step 2, you need to enable the FSE partition if it was

 

 

disabled, or add it if it was removed.

 

 

To enable the FSE partition, use the command:

 

 

fsepartition --enable PartitionName

 

 

To add the FSE partition, use the command:

 

 

fsepartition --add PartitionName

 

5.

Mount the FSE partition on the client using fse --mount.

Description

If an FSE partition is removed from the FSE configuration, with the associated HSM file system

 

left intact, this HSM file system cannot be mounted again even when the FSE partition is

 

configured with the same parameters.

Explanation

After an FSE partition is removed, its associated HSM file system cannot be used with a newly

 

added FSE partition. Before it can be assigned to a new FSE partition, such HSM file system

 

needs to be re-formatted and its HSMDB removed from the corresponding directory.

Workaround

None

Description

After FSE processes are started, the FSE partitions are not reported as being 'mounted' by the

 

fsepartition -l -D command.

 

(Linux system specific)

Explanation

Inappropriate values in entries for HSM file systems, specified in the local file /etc/fstab,

 

prevent partitions from being mounted.

Workaround

Check contents of the file /etc/fstab and modify them appropriately.

 

Linux specific

 

For information on the correct values, see the FSE installation guide for Linux, chapter ”Installing

 

FSE software”, section ”Automating the mounting of HSM file systems”.

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.
