    SubjectRereading disk geometry without reboot
    I am using linux kernel 2.6.9 on a san.  I have file systems on
    non-partitioned disks. I can resize the disk on the SAN, reboot and grow
    the XFS file system those disks. What I would like to avoid rebooting or
    even unmounting the filesystem if possible.

    Is there any way to get the kernel to re-read the disk geometry and change
    the information it holds without rebooting or reloading the module (which is
    as bad as a reboot in my case)?

    Thanks,

    Andy
