Hello,

my Windows 7 crashed and put the fake-RAID1 in Verify-state.

Previously the verification of the fakeRAID1 was possible with SuSE
12.1 like this:

cat /proc/mdstat
Personalities : [raid1] [raid0] [raid10] [raid6] [raid5] [raid4]
md126 : active raid1 sdc[1] sdd[0]
1953511424 blocks super external:/md127/0 [2/2] [UU]
[==>..................] resync = 10.5%
[(205884736/1953511556) finish=361.1min speed=80657K/sec

md127 : inactive sdc[1](S) sdd[0](S)
6056 blocks super external:imsm

unused devices: <none>

But now there is a different situation:
the whole thing does not boot to SUSE12.1, boot partiton is on some
SSD and it says that it does not find
/dev/disk/by-id/md-uuid-49818217:13c92065:79a2503c:31fc331d-part2
which is the boot partition according to /boot/grub/menu.lst .

But I guess the RAID1 is the problem to be solved first, since in
the Verify-state it does not come up: cat /proc/mdstat
Personalities : [raid1] [raid0] [raid10] [raid6] [raid5] [raid4]
md126 : inactive sdc[1] sdd[0]
3907023112 blocks super external:-md127/0

md127 : inactive sdc[1](S) sdd[0](S)
6056 blocks super external:imsm

unused devices: <none>

I am not that RAID expert so any help to activate this fakeRAID1
and start verifying would be appreciated.

Any ideas how to get this Intel fake-RAID1 active again?

Isn't this more likely a job for some Intel utility or BIOS setup? I
have never played with mdadm and external raid setups though.

I have also thought of putting one of the fake-RAID1 HDDs out of the
machine, make a backup of the most important things (will take quite
long) with some USB-SATA-adapter and then try the BIOS setup of the
RAID.
:-(
But since mdadm was once able to do the verification I have the idea
that this would be some better way to let mdadm switch on the
verification of the raid1.

Well, I have no experience with IMSM, but although mdadm appears to
understand the metadata, I think I would try the manufacturers tools
first. Especially as you can't even boot.
