I installed Ubuntu 18.04.2 a few days ago. It's installed on a 250GB SSD and I also have a RAID0 that I configured through the Intel Rapid Storage BIOS with two 2TB Enterprise drives. Now for some reason the 2 drives show up as sdb and sdc but also the 4TB RAID Volume shows up and I can use it. GParted gives me 2 Errors every time I start it and under fdisk -l there are 16 loop devices. I mean it works but it seems very weird and although a RAID0 is more or less risky anyway I don't want to loose the data only because something is configured wrong.
Is there something I can do to fix this?



The two GParted Errors:



The first error message is german and roughly says "The argument is invalid, while /dev/sdb is positioned to read from"



First Error



Second Error

      partitioning hard-drive raid loop-device







      share|improve this question














      I installed Ubuntu 18.04.2 a few days ago. It's installed on a 250GB SSD and I also have a RAID0 that I configured through the Intel Rapid Storage BIOS with two 2TB Enterprise drives. Now for some reason the 2 drives show up as sdb and sdc but also the 4TB RAID Volume shows up and I can use it. GParted gives me 2 Errors every time I start it and under fdisk -l there are 16 loop devices. I mean it works but it seems very weird and although a RAID0 is more or less risky anyway I don't want to loose the data only because something is configured wrong.
      Is there something I can do to fix this?



      The two GParted Errors:



      The first error message is german and roughly says "The argument is invalid, while /dev/sdb is positioned to read from"



      First Error



      Second Error
