Funny thing is 10.10, 11.4, and 11.10 were fine with the array's in place once 12.4 made the rounds it fell over. If i knew more about grub and udev i could probably bring it back up.
Hmmmm, that should have been good enough, but I guess they could have put it in the middle. It's not unheard of.
Like I said, something is triggering that device mapper on your drive, so there has to be something on the drive that it likes.

Did you zero the drive all the way to the end, or just the first
part. Also maybe you zeroed the partition and not the drive? Many of
the raid superblocks are at the very end of the drive, and it would
still be catching them if you haven't done the whole thing.
I really think this is whats happening since the Device Mapper is
trying to grab hold of it.

well 4 of the 6 drives involved are actively part of a raid.
the one
i am using for Linux was already 0ed for that very reason, i do
still
have a usb HDD still attached so i will try disconnecting that.
odd thing is i was able to boot a 10.10x64 no issue and installed
there and have been doing dist-upgrades to current. i will take
a 2nd
look but its is really puzzling.
I will certainly have to keep an eye out. I haven't even figured out
how i'm going to configure grub yet to get multiple boot set up.
i may
leave it ghetto and just use bios.

The fact that the device mapper is getting involved with the

to believe that the drive was part of a raid, or at least
configured by your
raid controller at one time and there is now a superblock on
it that is
messing up everything.
You'll probably need to zero out that superblock before
things will start to
behave correctly.

I have an AMD based chiset and i am trying to get ubuntu
to boot right
now and it is stalling, and i am having trouble ironing
out what is
going on.
I have onbaord raid drives attached to the onboard raid
chipset
(SB710) however i am not intending to install to those
drives the
drive i wish to install to is actually a SATA connected
single drive
but i am having the worst time getting Ubuntu 12.04 to
even finish its
boot cycle. and im not getting allot of feedback.
The errors i am getting are ata_id[336]:
HDIO_GET_IDENTITY failed for
'/dev/sdb': Invalid argument
- this is with all Raid disks disconnected and raid
turned off in
bios. just a single SATA HDD
I get one of the two following errors if i have raid
disks attached
A similar entry as above comes up or i get
udevd[167] inotify_add_watch(6, /dev/dm-1, 10) failed:
No Such file or
directory
the most promising option i have so far is booting with
nodmraid but
it seems to just hang and go no place after detecting my
CDrom devices
This is rather perplexing overall.
Ideally i would like my 2 onboard raids to be connected
running
windows and then let linux run amok on my extra sata hdd
but it either
is really pissed off in a way i cannot figure out or it
really does
not like that port.
Anyone have any thoughts?
