IMAP Server Issues post Update/Rollback

Update 22:56:37 PDT: Everything looks good and all services appear to be functioning.

Update 21:37:03 PDT: The final cohort has been enabled.  We’ll continue to watch the cluster for next several hours to ensure that everything is working as intended.  It will still take some time before we’ve regained expected performance.

Update 19:17:35 PDT: Approximately 5/6 of user’s access to mail spools has been restored.  We’re still on target for having services fully restored in a few hours.

Update 17:39:57 PDT: Approximately 2/3 of user’s access to mail spools has been restored and while users can expect slow performance, the cluster and storage pools appear to be stable and chugging along.  At this point, we expect to have services fully restored later tonight.  Please note that no email was lost during this outage and our inbound servers were able to deliver mail without issue.

Update 16:19:00 PDT: The status of our email system is continuing to improve – we will post an update as our systems return to normal operation.

Update 13:00:56 PDT: In order to allow the cluster to recover we’ve taken steps to reduce the total number of user who can log in at once.  This appears to be having positive results and is allowing the storage pools to catch up with the load.  We still don’t have an ETA but the situation is improving.

Update: We believe the underlying issues have been been resolved.  However, it will take some time for IMAP and POP services to return to normal.  The fix has resulted in substantially increased IO load on our mail spool storage as all mailbox indexes have to be rebuilt.  This rebuild process can take a long time to complete, especially for large mailboxes, and it will be some time before the process is complete for all active mailboxes.

Update: We’re continuing to restore services for effected users.  Please note this may also affect some Fusion DSL user’s voicemail services.

Update: mailboxes for many users have been fixed and are working properly.  We’re continuing to repair remaining effected users.

Unfortunately, the mail server upgrade and rollback has caused issues for our IMAP cluster and it looks like most IMAP sessions are failing.  We’re working to restore services ASAP and will have more information forthcoming.  -Kelsey and Grant.
