    Making 3 Disks Look Like 1 Big Disk

    Hello,

    The SAN admin where I am wants to keep a standard of all disks to be 2 terabytes (hardware-wise). Though I have no issue creating a 6 terabyte volume in Linux they want to present it to me as 3 x 2-terabyte disks. I could partition each but that would functionally give me 3 disks where I want just one (1) that looks like 6 terabytes.

    How can I make 3 x 2-terabyte disks look like just 1 x 6 terabyte volume?

    For instance, if I was to do a df -h it should show as 1 x 6 terabyte volume.


    Thanks for your advice,

    Michael

    Use LVM to combine the physical disks into a logical volume.

    https://docs.fedoraproject.org/f26/i...nding_LVM.html

    That first link from the Fedora docs wasn't particularly enlightening. Here is a more complete description.

    Or you could set up a raid 0 or linear raid using mdadm.

    I have my own lvm page, which, although somewhat dated, some folks liked.
    http://srobb.net/lvm.html (and it gives links to better pages).
