    Dear fellows I could really use some insights here.
    24:30 hours back I started moving from mbox to maildir, God how much I regret this!

    17 HOURS later I Got this:

    ..........................................................
    Broadcast message from root (Wed Sep 5 04:28:36 2007):

    cPanel Layer 2 Update Commencing
    .............................................................................................................
    Broadcast message from root (Wed Sep 5 04:30:27 2007):

    cPanel Layer 2 Install Complete
    .............................

    And the process still goes on and on. 24:0 minutes have passed since I started.
    I have 200 domains hosted (average 3-4 mailboxes per Domain) Pentium 4 2,8

    Since the message does not clarify what is going on or where in the process we are in...
    Can someone tell me if this is normal, and a ballpark figure how long it might take?

    I have tons of customers requesting support since they can't access their accounts for over 24 hours. :-(

    Thanks in advance for any help.

    I've heard of the process going to several days for servers hosting many multi-gigabyte accounts. Essentially it's not so much the number of accounts as the amount of mail stored in those accounts that needs converted.

    Gosh!

    Please do not tell me this! :-(

    The Notice when upgrading does ONLY show AFTER you start the process and can not be stopped.
    Even so, it says it may take from 5 minutes to 24 hours.

    It is over 25 hours for me now and what I am scared of is that, even though I am on a cable connection, sometimes it drops. How scary is this?

    The total amount of disk space used is 8.4 Gigabytes. Do you think it might take days?!

    Just in case, is there any way to stop and revert? Something there I won't do.

    IF, for some reason the connection drops, is there a way to fix what might break? Just wondering...

    Thanks David!

    Are you saying the total space for ALL the domains (that is the /home) is 8.4 gigs or that the email is 8.4 gigs?.

    If its the first it should not be taking that long. We had a machine with 400 accounts, totalling 39gigs filespace in /home and the conversion took about 25 minutes on a AMD 64 3500 with an 80gig IDE UDMA100 drive.

    What should I do?

    In fact we have 167 domains hosted.

    the TOTAL amount of disk space used for all acounts/cpanel etc is 8.4 Gig.

    -----------
    /dev/hda3 75G 8.4G 63G 12% /
    -----------

    Here is the server config

    Processor #1 Name: Intel(R) Pentium(R) 4 CPU 2.80GHz
    Processor #1 speed: 2800.162 MHz
    Processor #1 cache size: 1024 KB

    I though it should not take that long either. Is there any way to see the status?

    I am quite desperate. ANY insights are deeply appreciated.

    If you can SSH into the console again you should be able to to a 'ps ax' or something like it to see whats going on. Same can be done from WHM, since you can log into that and do a show whats running.

    It might not give you very specific detail but at least you might be able to see if something is really running and not just looping or stuck waiting for some kind of I/O.

    Thanks nyjimbo

    Thanks for the insights, really, but I am a total SSH/*nix commands dumb and the person responsible for that is on vacation and I am unable to reach him. :)

    The running processes at WHM make it hard to understand what is going on.

    I'll try posting a Support Ticket to the CPanel tech guys.

    Best wishes!

    If someone have any other ideas, pls don't be shy.
    :)

    The bottom line - You should read and learn from our experience.

    If we have read this it would save us a LOT of trouble.

    The convertion from mbox to maildir SUCKS.

    We TOTALLY do NOT recommend or at least that you consider it carefully and plan to do it during the holidays in case something go wrong.

    The process of migrating from mbox to maildir does ONLY inform how long it might take AFTER the process begins;

    Users will have their email (pop) blocked until the process ends. This is NOT informed prior to the installation. It means you will probably receive TONS of support from your users.

    Neomail will NOT be available anymore. Some of our users are NOT happy. THis is NOT informed at all by the installer.

    The update might hung and then you are pretty much screwed. It happened to us.

    There are some reports from users that have lost email messages on secondary mail boxes (not the main ones associated with the account). I am not quite sure if this is true or not.

    DO a BACK-UP prior to converting. Any other previous backup won't help since it will be on the old mbox format.

    DO NOT (EVER) INTERRUPT THE PROCESS. In our case in hung, and we were screwed. If your internet connection drops during the process, you are screwed.

    We had to restart our server from WHM and it was unaccessible, requiring a manual restart. Our server was down for a few hours. The data center problem anyway, but it might happen to someone else.

    Very unfortunately, the CPanel Team was not able to help during the process, even though it was caused by THEIR system and installer and which is recommended, pretty much mandatory since it will be required from version 12 and beyond.

    In order to help others. We have a Pentium IV 2.8 with 170 domains hosted (no more than 6 email accts oer domain), a total disk space used of 8.5 Gigabytes. It took us 15-20 minutes to convert (the second time).

    The first time though, our server was hung for OVER 30 hours, so, consider this before converting.
    The converter script does ONLY say it might take 5 min- 24 hours to complete. You are completely BLIND during the process. After 30 hours we "suspected" something might be wrong. :)

    The bottom line: we will never, ever, do any manual update before checking the forums for reported problems.

    I sincerely hopes it helps others.

    Do you have a ticket ID reference I can look at to see where we were unable to help as you claim?

    Note, this is not a support forum - this is a community forum. cPanel staff members do not routinely monitor these forums as a result.

    Go on, have a guess
    Which is indeed the moral of the story as it's well documented going back around a year on the forums about the issues you've seen.
