[Bug 1508885] Re: RAID0 install on 2 x 120GB Samsung Evo840 SSDs

[Phillip Susi]

"After searching before submitting this report I have learned that SSD
support for RAID is not yet implemented in Ubuntu."

No... SDD, HDD, usb flash drive, or loopback file... mdadm doesn't care;
it works on anything.

The problem appears to be that grub can't find the raid array and the
partitions it contains.  I suspect this is due to the fact that you are
using an intel fakeraid, which is now handled by mdadm instead of
dmraid, and grub hasn't been updated to handle this ( since it still is
a fakeraid even though it is handled by mdadm ).

Title:
  RAID0 install on 2 x 120GB Samsung Evo840 SSDs

Status in grub-installer package in Ubuntu:
  New

Bug description:
  After searching before submitting this report I have learned that SSD support for RAID is not yet implemented in Ubuntu. Nevertheless, I thought that this information may still be assistive to a developer.
  Process was a standard installation attempt, after 20+ attempts in different configurations of RAID0 & Fake-RAID0, all without success, boot-repair was then installed and different repair attempts were made, all without success.
