      I had planned to really jump into some Linux learning here in 2016. I've spent my whole life in Windows.

      I can do the basics now, but things like disks and partitions still seems to get to me.

      I have a few things I am trying to do in the filesystem, and could use some guidance.

      First of all, I would like to remap /var/log from the USB boot device (/dev/sdc) to another partition.

      Currently, I have the USB stick, and my RAID array. I'd like to figure out if XS used all the space on the array, or if I could put it there.

      This is my listing of fdisk -l .... the issue is, I can't figure out where the array is the is storing all the VDIs. I know it is the /dev/mapper one, but I do not understand that syntax.

        Basically it is identical to Windows minus the unnecessarily complex and confusing drive letter names. Most everything works exactly the same.

            Yeah, once you know it.

              Look in /etc/fstab and you'll see where the mount details are coming from. Pretty sure that your RAID array just has LVM on it.

                If you know it from Windows, it all just tags along.

                  CD into the SR and see what is there...
