Thread: Possible fragmentation issue?

  1. Possible fragmentation issue?

    We recently had a repeating issue wtih one of our main file servers. It's an
    HP DL380 G4 with 850GB of storage space on the D:\ drive. It's currently
    operating with 5-70GB free space (fluctuating quite regularly). A month ago
    on a weekly basis the server would just stop responding. At the times we had
    50+ GB available (we've been as low as 1mb free and not had the issue).
    Connecting to the server via any method was near impossible.

    I managed to log in to the console without any problems what so ever. I
    started looking at services, memory, CPU usage etc from the console, couldn't
    find a problem what so ever. Next to no network traffic, next to no disk
    activity. Nothing in the event log to indicate a problem. As far as the
    console and all applications installed were concerned, nothing was wrong.

    I started looking at the hard drives, browsing the C:\ drive was ok, but
    browsing D:\ was problematic. Sometimes certain directories would respond
    perfectly, other times they would take a long time. Occasionally not even at
    all. Due to increasing call volumes and lack of evidence as to the actual
    cause of the problems (just symptoms as described), the server was bounced
    and would operate again for another week (give or take).

    As a stab in the dark I installed a trial version of DiskKeeper and kicked
    off regular defrag jobs. We haven't had the problem since.

    Has anyone else noticed any fragmentation related issues or are there any
    known fragmentation related issues with Windows Server 2003 SP1? I am yet to
    find anything that could help me out here. The best thing is, this same
    problem has now started ocurring on our Citrix servers. One got rebooted
    late last week, now the other is doing the same.

    The Citrix servers have been live for about 10 months. They're both
    reporting 15% total fragmentation and 30% file fragmentation. That does seem
    quite excessive so they're both getting a defrag tonight from the built-in
    defrag tool. My biggest concern is if this is a problem with Windows 2003
    SP1 - the last time I recall having to defrag a machine was Windows '98. I
    recall one of the great publicised aspects of Windows 2000 as it was getting
    introduced was that defragging was no longer required.

    Is the monkey back?

    You were misinformed by someone who doesn't understand how drives work. It
    is a known issue with severe fragmentation that not only will you not be able
    to mount the system but you can't even repair it. It has to be wiped and
    reinstalled.

    I have personally seen this with a XP pro workstation that staff neglected
    to auto schedule Diskeeper.

    All MS server and workstations need to be defragged. Until the OS can write
    files to the disk defragged [like Netware does] this "monkey" will be with us
    for a long time.

  3. Re: Possible fragmentation issue?

    That level of fragmentation is not that big. I've seen live servers with
    much, much worse (50%+). You should contact MS-Support and get this
    diagnosed. There are a lot of things that could be playing here -
    Anti-virus, memory leaks, etc.
