I have created an Intel RST hardware RAID-0 array from 2 500 MB HDDs. Ubuntu 18.04 detects this to my pleasure. However when I get to the "[!!] Partition disks" menu it either is too advanced for me understand, even with the manual, or there is some sort of idiosyncratic critical problem I am having.

I only have the options to "Configure iSCSI volumes," "Undo changes to partitions" (This option results in an unrecoverable error), and "Finish Partitioning and write changes to disk." The first option I am completely lost on and the last option gives the error "No root file system is defined. / Please correct this from the partitioning menu." My attempts to configure iSCSI has always ended in this error: "No iSCSI targets were discovered on [Attempted ID]" See attached photos --> Limited Partition Options. Cannot install root file. Cannot figure out iSCSI.

Thanks in advance, Austin

  • Thank you Zanna, but it was me. I've never had such a problem installing any linux distro on Intel Raid 0. I do not know why the setup changed, then it changed back to original problem. I figured out iSCSI and that has nothing to do with the RAID 0 already setup preboot. I finally gave up and deleted the Intel Raid array and just installed a software raid. Things are working good enough. – Arrrstin Jun 23 '18 at 20:22

I used a drive to install 18.04 first. Then add the array into the system with Intel RST. The first drive sda has the U18.04. Then sdb, sdc, sdd is my RAID0 array.
