User Mailbox Directory Problems

A user mailbox problem exists when the damage to the message store is limited to a small number of users and there is no global damage to the system. The following guidelines suggest a process for identifying, analyzing, and resolving a user mailbox directory problem:

  1. Review the log files, the error messages, or any unusual behavior that the user observes.

  2. To keep debugging information and history, copy the entire store_root/mboxlist/ user directory to another location outside the message store.

  3. To find the user folder that might be causing the problem, run the command reconstruct -r -n. If you are unable to find the folder using reconstruct, the folder might not exist in the folder.db.

    If you are unable to find the folder using the reconstruct -r -n command, use the hashdir command to determine the location. For more information on hashdir, see The hashdir Utility and the hashdir utility in the Messaging Server Command-line Utilities chapter of the Sun Java System Messaging Server 6 2005Q4 Administration Reference.

  4. Once you find the folder, examine the files, check permissions, and verify the proper file sizes.

  5. Use reconstruct -r (without the -n option) to rebuild the mailbox.

  6. If reconstruct does not detect a problem that you observe, you can force the reconstruction of your mail folders by using the reconstruct -r -f command.

  7. If the folder does not exist in the mboxlist directory (store_root/mboxlist), but exists in the partition directory store_root/partition), there might be a global inconsistency. In this case, you should run the reconstruct -m command.

  8. If the previous steps do not work, you can remove the store.idx file and run the reconstruct command again.

    Caution – Caution –

    You should only remove the store.idx file if you are sure there is a problem in the file that the reconstruct command is unable to find.

  9. If the issue is limited to a problematic message, you should copy the message file to another location outside of the message store and run the command reconstruct -r on the mailbox/ directory.

  10. If you determine the folder exists on the disk (store_root/partition/ directory), but is apparently not in the database (store_root/mboxlist/ directory), run the command reconstruct -m to ensure message store consistency.
