lost+found

. This directory is required for file system integrity and should not be deleted.

Viewing disk space information from a Linux X9000 client

Because file systems are distributed among segments on many file serving nodes, disk space utilities
such as df must be provided with collated disk space information about those nodes. The Fusion
Manager collects this information periodically and collates it for df.

X9000 software includes a disk space utility, ibrix_df, that enables Linux X9000 clients to
obtain utilization data for a file system. Execute the following command on any Linux X9000 client:

ibrix_df

The following table lists the output fields for ibrix_df.

Extending a file system

You can extend a file system from the GUI or the CLI.

NOTE:

If a continuous remote replication (CRR) task is running on a file system, the file system

cannot be extended until the CRR task is complete.

If the file system uses tiers, verify that no tiering task is running before executing the file system
expansion commands. If a tiering task is running, the expansion takes priority and the tiering task
is terminated.

Select the file system on the Filesystems top panel, and then select Extend on the Summary bottom
panel. The Extend Filesystem dialog box allows you to select the storage to be added to the file
system. If data tiering is used on the file system, you can also enter the name of the appropriate
tier.
