*bump*
Still scratching my self for a solution ....
doing a vgscan will get me this
Code:
steliosph@Stelios-Home:~$ sudo vgscan -d -v
DEGRADED MODE. Incomplete RAID LVs will be processed.
Wiping cache of LVM-capable devices
Wiping internal VG cache
Reading all physical volumes. This may take a while...
Finding all volume groups
No volume groups found
Code:
steliosph@Stelios-Home:~$ sudo mdadm --assemble --scan -v /dev/md0
mdadm: looking for devices for /dev/md0
mdadm: no RAID superblock on /dev/sde5
mdadm: no RAID superblock on /dev/sde2
mdadm: no RAID superblock on /dev/sde1
mdadm: no RAID superblock on /dev/sde
mdadm: /dev/sdd1 has wrong uuid.
mdadm: /dev/sdc1 has wrong uuid.
mdadm: no RAID superblock on /dev/sdc
mdadm: /dev/sdb1 has wrong uuid.
mdadm: no RAID superblock on /dev/sdb
mdadm: /dev/sda1 has wrong uuid.
mdadm: no RAID superblock on /dev/sda
mdadm: /dev/sdd is identified as a member of /dev/md0, slot 3.
mdadm: no uptodate device for slot 0 of /dev/md0
mdadm: no uptodate device for slot 2 of /dev/md0
mdadm: no uptodate device for slot 4 of /dev/md0
mdadm: added /dev/sdd to /dev/md0 as 3
mdadm: /dev/md0 assembled from 1 drive - not enough to start the array.
** Edit
So i removed the /etc/mdadm/mdadm.conf and executed the command again
Code:
steliosph@Stelios-Home:~$ sudo mdadm --assemble --scan -v
mdadm: looking for devices for further assembly
mdadm: no recogniseable superblock on /dev/sde5
mdadm: Cannot assemble mbr metadata on /dev/sde2
mdadm: no recogniseable superblock on /dev/sde1
mdadm: Cannot assemble mbr metadata on /dev/sde
mdadm: no RAID superblock on /dev/sdc
mdadm: no RAID superblock on /dev/sdb
mdadm: no RAID superblock on /dev/sda
mdadm: /dev/sdd1 is identified as a member of /dev/md/0, slot 3.
mdadm: /dev/sdc1 is identified as a member of /dev/md/0, slot 2.
mdadm: /dev/sdb1 is identified as a member of /dev/md/0, slot 1.
mdadm: /dev/sda1 is identified as a member of /dev/md/0, slot 0.
mdadm: added /dev/sdb1 to /dev/md/0 as 1
mdadm: added /dev/sdc1 to /dev/md/0 as 2
mdadm: added /dev/sdd1 to /dev/md/0 as 3
mdadm: added /dev/sda1 to /dev/md/0 as 0
mdadm: /dev/md/0 has been started with 4 drives.
So it found the array (again and started it )
No rebuilding in cat
But still cant mount the array
Just found this . Is the MBR broken on the disks .. should i figure out how to fix that ?
Why is it correct on [1] ?

Another edit perhaps someone has any idea
sfdisk -d /dev/sd[abcd]
Why is sdb bootable ?
Code:
# partition table of /dev/sda
unit: sectors
/dev/sda1 : start= 63, size=1953520002, Id=fd
/dev/sda2 : start= 0, size= 0, Id= 0
/dev/sda3 : start= 0, size= 0, Id= 0
/dev/sda4 : start= 0, size= 0, Id= 0
# partition table of /dev/sdb
unit: sectors
/dev/sdb1 : start= 63, size=1953520002, Id=fd, bootable
/dev/sdb2 : start= 0, size= 0, Id= 0
/dev/sdb3 : start= 0, size= 0, Id= 0
