I also have this issue with a Ubuntu 15.04 on a HP server with 3 disks in raid 5. It seems grub wants to test on one of the disks of my raid. This is really scary. Grub seems to want to mount the second disk of the raid separately??? Linux CmsrvVH3 3.19.0-30-generic #33-Ubuntu SMP Mon Sep 21 20:58:04 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux See log below...
(I have a the same server also with Ubuntu 14.04.3 LTS with 4 disks in raid 5 and 4 disks in raid 10. Here I don't have this issue.
