Troubleshooting (Zimbra)

Account Export Incomplete

When trying to export an entire (or partial) account's data (either via the web or Zimbra clients, or through a /zmmailbox -z -m "user@domain.com" getRestURL -o user.tgz "//?fmt=tgz"), the export can occasionally be incomplete, this can be due to two reasons (maybe more)...

• Large account / export time-out
  • If you've a large account, and/or a slow server, the export process can time out.
  • This is due to known bug - http://bugzilla.zimbra.com/show_bug.cgi?id=56458
• Invalid tags
  • This is essentially down to some database corruption.
  • To confirm that its the issue, tail your /opt/zimbra/log/mailbox.log file when creating an export and look out for the following errors (tag 68 is the problem tag ID in this example)
    • Code:mail.NO_SUCH_TAG Arg:(itemId, IID, "68")
    • java.io.IOException: data error: java.io.IOException: tag error: com.zimbra.cs.mailbox.MailServiceException$NoSuchItemException: no such tag: 68
  • To resolve...
    1. Confirm that the account doesn't have the tag
       • zmmailbox -z -m "user@domain.com" gat
    2. Get the user to create enough dummy tags to reach the problem ID number
    3. Reattempt the export - it may fail again, but on a higher tag ID (repeat the above until it succeeds)
    4. Delete the dummy tags, and retest

The above is based on info gleamed from http://www.zimbra.com/forums/administrators/48724-no_such_tag-while-exporting.html
