    file corruption

    I have two servers running Windows 2K3 Enterprise Edition connected to a disk
    storage unit via fiber channel. They are not part of a cluster, however,
    when connected the 2nd server to the disk unit, I started getting the
    following errors in the event logs of both servers:

    Event ID: 257, Source: PlugPlayManager
    "Timed out sending notification of target device change to window of
    "C:\WINDOWS\Explorer.EXE"

    Event ID: 55, Source: NTFS
    "The file system structure on the disk is corrupt and unusable. Please run
    the chkdik utility on the volume cluster set."

    When I look up these event ID's in Microsoft's Knowledgebase, The TID's
    state that these errors are informational and can be ignored. However, I am
    getting files that are being flagged as corrupt and cannot be accessed. When
    I reboot, the chkdsk utility launches on the drive they both are sharing on
    the disk unit.

    Please help. Thanks.

    Re: file corruption

    You cannot have two different servers accessing the same NTFS-disk
    simultaneously.

    You can NEVER have two different servers accessing the same NTFS-disk
    simultaneously

    When you do, you WILL have data corruption.

    Ensure only one server accesses a disk.

    rgds,
    Edwin.

    Re: file corruption

    I totally agree. The NTFS file system is not designed to handle multiple
    servers accessing it simultaneously. With Microsoft clusters, MSCS is a
    "Shared nothing" cluster model. MSCS has a built in filter driver that
    controls access to the disks. It is this cluster disk driver which prevents
    this sort of corruption from occurring in a cluster.

    Without cluster software to control access to the drive, corruption will
    always occur.

    Regards,
    John
