Bug 15791

HW: ASUS UX301 laptop, dual SSD in RAID 0, Win8.1 and M5, UEFI and GPT
Intention was to first write something on sda1 - anything- to break the RAID stuff

1. UEFI -> SATA config, switched RAID to AHCI
2. booted Classic RC x86_64, install from USB
3. Ctrl-Alt-F2: parted: not found, gparted: not found, partprobe: not found
4. at partitioning, sda highlighted, chose 'erase & use entire disk'
5. This failed: 'You must have an ESP Fat32 partition mounted in /boot/EFI'
6 I manually deleted the partitions, went back and chose 'erase and use entire disk'
7. Failed, same error
8. went back, chose 'custom' at this point.
made 300 Mb /boot/EFI on sda, used rest 238Gb of sda as / partition, -> Next:
9. 'An error occurred: ext4 formatting of sda2 failed'
10. Back into partitioning, highlighted EFI partition, toggle to expert mode, choose 'format'
11.'vfat formatting of sda1 failed'
12 Try again, highlighted EFI, selected 'Type'.  On entry, 'EFI System Partition' was highlighted.
13. Changed this; selected the entry above: 'EFI GPT', saved it
14. format: 'I do not know how to format sda1 in type.'
15. Had aonther try at sda2 ext formatting.
16. 'Ext 4 formatting of sda2 failed.'
17. switched to # prompt (Ctrl-Alt-F2)
18. 'gdisk'  
19 bash: gdisk: command not found
20 reboot, USB rescue mode, -> console.  gdisk shows the 2 partitions.
21. mkdosfs -F 32 /dev/sda1.  response: 'mkfs.fat 4.0 (2016_05_06)  seems OK
22. mke2fs -j /dev/sda2
23 response: 'Discarding device blocks', incrementing big numbers.
24 Is this destroying bits of my SSD!!  Terminated it!
25. Reboot -> UEFI, switched AHCI to RAID.  Sliently accepted with no further dialog.
26. -> install from USB, no pop-up dialog about RAID
27.  At partitioning, install sees only sda and sdb
28 reboot, install from USB
29 Ctrl-Alt-F2 # prompt
30. dmraid -ay   'wrong number of devices in RAID set
"isw_ceececifig_ASUS-OS [1/2] on /dev/sdb"
i.e. it is seeing the fragment of RAID on sdb, given I'd not written anything to sdb.
31 mdadm --detail-platform. 
RAID levels raid0 raid1
port 0; /dev/sda
port 1: /dev/sdb
nothing about any raid set.
32. mdadm --assemble --scan
33'Container /dev/md/imsm0 has been assembled with 1 drive.
/dev/md/ASUS_OS_0 assembled with 1 device but not started'
34 mdadm --detail-platform:  same as before, just sda and sdb
35.  ls /dev/mapper
36. Only the 'control' file is present
37. dmraid -ay   Same error as at (30) above.
38 partprobe: command not found.
39 urpmi partprobe.   urpmi: command not found.
