6.3 HP StoreAll Storage File System User Guide (TA768-96093, June 2013)

Unexporting a file system
A file system should be unexported before it is unmounted.
To unexport a file system:
• On the GUI, select the file system, select NFS Exports from the lower Navigator, and then
select Unexport.
• On the CLI, enter the following command:
ibrix_exportfs -U -h HOSTNAME -p CLIENT:PATHNAME [-b]
Using case-insensitive file systems
By default, StoreAll file systems and directories follow POSIX semantics and file names are
case-sensitive for Linux/NFS users. (File names are always case-insensitive for Windows clients.)
If you prefer to use Windows semantics for Linux/NFS users, you can make a file system or
subdirectory case-insensitive. Doing this prevents a Linux/NFS user from creating two files that
differ only in case (such as file1 and FILE1). If Windows users are accessing the directory, two
files with the same name but different case might be confusing, and the Windows users may be
able to access only one of the files.
CAUTION: Be careful when applying the case-insensitivity setting to an existing directory populated
with files. Make sure you do not have files with duplicate names but in different cases, for example
File1 and file1. If you edit one of the files (File1), the other file (file1) is changed to match
the contents of the edited file. Both files will contain the same data, resulting in the loss of data
from the other file.
CAUTION: This feature breaks POSIX semantics and can cause problems for Linux utilities and
applications.
Before enabling the case-insensitive feature, be sure the following requirements are met:
• The file system or directory must be created under the StoreAll File Serving Software 6.0 or
later release.
• The file system must be mounted.
Setting case insensitivity for all users (NFS/Linux/Windows)
The case-insensitive setting applies to all users of the file system or directory.
Select the file system on the GUI, expand Active Tasks in the lower Navigator, and select Case
Insensitivity On the Task Summary bottom panel, click New to open the New Case Insensitivity
Task dialog box. Select the appropriate action to change case insensitivity.
NOTE: When specifying a directory path, the best practice is to change case insensitivity at the
root of an SMB share and to avoid mixed case insensitivity in a given share.
