Reporting Bugs

(Updated: Dec 2009)

Bugzilla for Lustre™ is an issue tracker as well as a bug tracker. It is a one-stop repository for:

• Bugs
• Enhancement requests
• Patch submission
• Patch review and dependency tracking

A bug-tracking system is less-error prone and superior to email in dozens of ways. For this reason we ask that all the above issues be handled exclusively through Bugzilla.

All of the important links described below are accessible from the Bugzilla main page or the toolbar at the bottom of each Bugzilla page.

Opening an Account

To use Bugzilla, you will need to open an account. On the Main page, click on "Open a new Bugzilla account". After you enter a valid email address, an email will be sent to you confirming the creation of your account.

Searching for Bugs

You can search for bugs in Bugzilla in two ways:

• Enter the bug number or search on a keyword.
• Search on a specific field or specify detailed or complex criteria. For more information about advanced searches see the Bugzilla User's Guide

Filing a Bug

To file a bug, complete these steps:

1. Before opening a new bug report, do a quick search to avoid filing a duplicate bug.

2. To enter a new bug report, click on "New" or "Enter a new bug report".

3. In the bug report form, fill in as many fields as you can. If your version of Lustre isn't listed, include it in a note in the bug summary so that we can add it to the list. Please choose the correct component.

4. Include a descriptive summary. At a minimum, include the following:

• Describe the problem that you're solving, the feature that you're adding, or the enhancement that you're requesting.
• If you are reporting a bug, describe precisely the behavior that you're seeing and the behavior that you think is correct.
• Provide a minimal a test case. For example, if 'tar' is crashing, try to narrow the issue down to a specific syscall. If you have tried to narrow it down without success, tell us what you tried.
• If you are submitting a patch, see Submitting Patches for a detailed procedure.

Including Diagnostics Information in a Bug Report

A Lustre diagnostics tool is available for downloading at: http://downloads.lustre.org/public/tools/lustre-diagnostics/. You can run this tool to capture diagnostics output to include in the reported bug. To run this tool, enter one of these commands:

• lustre-diagnostics -t <bugzilla bug #>
• lustre-diagnostics.

Output is sent directly to the terminal. Use normal file redirection to send the output to a file, and then manually attach the file to the bug you are submitting.

Priority Bugs

If you have a support contract for Lustre with Oracle, you will see a group membership tick box. Use this box to indicate that the bug is important for your project.

Note: S1 (Critical) bugs can be filed only for corruption events or by customers with support contracts who are experiencing a production outage event.
