My name is Paolo from Italy (bad english)

I am using a Ubuntu 10.04 x64 desktop and try to create a raid1 with a couple of disk.
After the removal of the super block from the 2 discs (--zero-superblock) I assembled the raid with the command
"mdadm --create --auto=md -b internal --symlink=no -l raid1 -n2 --force /dev/md0 /dev/sdc /dev/sdd"
My intention is not to partition the raid (md_d0p1, md_d0p2, etc..); does not create links to the disks in /etc, and finally have the bitmap in order to accelerate the reconstruction.
After launching the command, the construction is done and the raid is completed. Format the new device /dev/md0 and everything works.
After rebooting the operating system the problem start.
1.Mdstat reports:
paolo@machiavelli:~$ cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md_d0 : inactive sdd[1](S)
312571136 blocks
2.and in /etc I find the device md0 partitioned into 4: md_d0p1, md_d0p2,md_d0p3,md_d0p4
I do not understand why then the device /dev/md0 became /dev/md_d0, despite the command --auto=md
also do not understand why the device md_d0 is inactive and mdstat shows a (S) (I can not find documentation about this symbol)
It seems that the options "--auto=md --symlink=no" wonts work!
Or maybe the mdadm command syntax is wrong?
Thanks
