How can you go about partitioning Ubuntu so that it spans multiple disks during the installation process of Ubuntu Server 15.10? Is it even possible to do this?

  • You would need to decide which directories lived on which drive. This can easily be set up during installation. Another option would be LVM. – earthmeLon Feb 20 '16 at 20:19
  • Do you mean a RAID like setup, or just separate / and home? – mikewhatever Feb 20 '16 at 20:20

  • It's fairly obvious to me this is an installation script question. It is also fairly obvious the OP wants to abstract a number of physical disks as a single logical volume during the install, say to effect /dev/sdnn as a mountpoint for / as an 40TB SCSI device with 4 10TB HDD's. What is the issue with comprehending this ? – mckenzm Nov 22 '18 at 22:01

Use Logical Volume Manager(LVM) for this. I have a detailed thread which talks about this topic. It has some other pointers(references) also.

In general the OOTB Ubuntu creates two partitions for you - root(/) and swap.

But you would like to have /usr, /opt, /home, /var on different logical volumes which can span across the disks(and giving you flexibility to add the disk to the logical group/volume later if needed).

  • This is typically done for /var to get it off SSD, and for where a stack of HDD's is required for MySQL. Setting up LVM to span a bunch of disks should be possibly during install. The question is about the install script, not about merging later. It's a moot point for 15.05 arguably, but should apply to any LTS release. – mckenzm Nov 22 '18 at 22:06
