    Hi, Praveen,

         There are 2 ways:
    1. Use df finding which lv for this fs, then change lv size 1st, and
    increase fs, since when you change lv size, you can decide which disk you
    will use

    2. Increase fs directly, then use migratepv to move some space to the disk
    you want.

    Re: ??: Disks used by LV






    Hi Andy,
     
        To put it short,I would like to know the following info.
     
    I have a FS fs01 of size 5GB on an LV that has been created on hdisk1
    which is of 18GB. This PV belongs to a vg called dbvg, which has 5 other
    disks which have a lot of free space. Now my question is if I increase the
    file system fs01 to 20GB, from which disk does the system pickup the
    excess 2GB space required for this file system. Is this random or can I
    make a choice saying please pickup only from hdisk2 ?
     
    I have tried all the below commands except migratepv before putting it in
    the forum, but of no use.
     
    I hope you have got my requirement.
     
    TIA
    Praveen

    Hi,

        Sorry, I cannot understand your words, but I do think that the
    following command should be useful:
    df
    lslv -m lvname
    lspv -l lvname
    migratepv
