Best practice for resizing VXVM volumes?

Hi,

What's the recommended practice for resizing a VXVM volume and filesystem?

Thanks!

  • Use "vxasisst maxgrow" to see how much space is available and add extra disks to diskgroup using "vxdg adddisk" if there is not enough space.  Then use "vxresize" which resizes both volume and fileystem.  Example:

    vxassist -g testdg maxgrow vol1

    vxresize -g testdg vol1 +50g

  • Hello,

    depends on how are you resizing the volume & filesystem..

    1. You may resize by adding new Luns to diskgroup

    2. You may resize by extending existing Lun from Storage (Dynamic Lun expansion)

    For first case, refer

    For later one, refer
