Problem description:

I have a linux software raid10 using four discs (SAMSUNG HD103SI 1TB Sata) created with the following command:
mdadm --create /dev/md0 --assume-clean --chunk=128 --level=raid10 --raid-devices=4 --spare-devices=0 --layout=f2 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sde1

On this md0 i created a ext4 filesystem using:
mkfs.ext4 -O large_file,dir_index,sparse_super -E stride=32,stripe-width=128 -b 4096 /dev/md0

After doing some load on the disks, coping some files and so on, i rebooted the machine. I tried to mount the filesystem after the reboot manualy, but i couldnt, i was advised to run fsck, which gives me errors:

[root@hal9000 ~]# fsck /dev/md0
