* /dev/nvme1n1 (aka the 512 GB M.2 drive)
** half (~256 GB) as primary partition. use as swap space (bootable flag off).
** the other half (~256 GB) as primary partition. use as ext4 filesystem, mount: /var/postgresql(choose "Enter it manually" in the mount point selection menu), bootable flag off.
* for each of the four 3.0 TB hard drives (aka /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd)
** 10 MB primary partition, use as "reserved BIOS boot area" (bootable flag can't be changed, so leave it set to off)
** the rest of the space as a primary partition, use as ext4 filesystem, mount to /bulk(choose "Enter it manually" in the mount point selection menu), bootable flag off
Then choose "configure software RAID" to set up the software RAID device. Confirm the partitions. Then wait for the disks to be partitioned. Choose "Create MD device" and then "RAID10" to begin. Use 2 active devices and 2 spare devices. For the two active devices, choose /dev/sda2 and /dev/sdb2. For the two spare devices, choose /dev/sdc2 and /dev/sdd2. Confirm the partitions that will be changed. Then wait for the device to be created. When you get back to the software RAID configuration menu, choose "Delete MD device" and then choose the software RAID device that was created (there should only be one, and it should be named something like "md0_raid10"). Note the device name (in this case, it is /dev/md0) and check that the component devices are correct. If they're correct, choose "No" (to not delete the software RAID device). This will take you back to the software RAID configuration menu, where you can choose "Finish" to set up the RAID device, which should now appear at the top of the partitioner. Choose the 3.0 TB partition in the RAID device and configure it to use as ext4 filesystem and mount point /bulk (choose "Enter it manually" in the mount point selection menu). Then choose "Finish partitioning and write changes to disk" at the bottom of the partitioner menu. Confirm that the partition changes to be made are correct. Then wait for the partitions to be formatted.
