2 Creating and mounting file systems

This chapter describes how to create file systems and mount or unmount them.

Creating a file system

You can create a file system using the New Filesystem Wizard provided with the GUI, or you can
use CLI commands. The New Filesystem Wizard also allows you to create an NFS export or an
SMB share for the file system.

File systems are created in 64–mode by default

Prior to StoreAll 6.1, file systems were created by default with 32-bit compatibility mode
enabled. Starting in 6.1 the default behavior has changed and compatibility mode is now disabled.
StoreAll creates file systems in 64-bit mode unless you changed the compatibility mode when
creating the file system. However, if the original file system was created with 32-bit compatibility
mode enabled and you later upgrade to 6.1 or later and then extend the StoreAll file system, new
segments will be formatted into the file system as 64-bit mode segments.

The 32-bit compatibility limits the number of inodes on any newly formatted segments to be 32-bit
addressable based on the segbits (number of bits allocated to inodes and segment numbers). If
you have a 32-bit client operating system and 32-bit applications, the 32-bit compatibility mode
should be enabled.

The following output shows the relevant portion of the output from the ibrix_fs -f fsname
-i

, indicating how newer segments (65,863,680) appear on a file system originally created with

compatibility mode enabled.

NOTE:

The 12th column (“FFREE”) is your total available inode count per segment for the original

segments 66 Million per segment and that of the newer 64 bit segments of 1 billion per
segment. This segment mix and inode count does not negatively affect the operation of your file
system nor any applications.

Using the New Filesystem Wizard

To start the wizard, click New on the Filesystems top panel. The wizard includes several steps and
a summary, starting with selecting the storage for the file system.

NOTE:

For details about the prompts for each step of the wizard, see the GUI online help.

On the Select Storage dialog box, select the storage that will be used for the file system.
