Public bug reported:
Intel Smart Response creates a 1 drive "RAID0" on the cache drive, and
puts the SSD data partitions on top. It also converts the accelerated
drive to a 1-drive RAID0.
The dmraid-activate script assumes all RAID0 instances must have at
least 2 drives, and fails to activate without printing any error
messages, assuming drives are still coming online. This is particularly
problematic in a dual-boot situation where Windows configures the SSD as
cache with Intel SRT.
Attached is a patch to fix this.
** Affects: dmraid (Ubuntu)
Importance: Undecided
Status: New
** Patch added: "Remove assumption that Intel RAID0 has a minimum of 2 drives."
