    Specify the hdisk number when creating the logical volume.

    Subject: Disks used by LV

    Hi,

            I have a vg called dbvg which is made of 5 disks, where I am going
    to create 5 File systems. Out of these 5, three of the fs are IO intensive.
    I want to create 5 logical volumes one each for 5 file systems on each
    individual disk. Also in future when I extend my one of the IO intensive
    file system (say fs01), this should not occupy the disk space on the disk
    were I already have another IO intensive fs (fs02), so I think I can choose
    the disks where I would want my IO intensive file system(fs01) be spread
    when the corresponding disk has no space left on it. Please correct if I am
    wrong in saying this.

    Say I have created a logical volume with the above preferences, now I would
    want to check what are the disks my IO intensive file system is going to
    use.

    Can some let me know how to check what are the disks a logical volume is
    going to use once that specific disk is full.

    TIA
    Praveen.K
