RAID5 with 6 HDD doesnt start any more

Hello!

Today I got a Problem with my RAID5. When I have a look on cat /proc/mdstat my Raid in inactive.
I try to stop and assemble it. But it didn´t work and i do really have no idea what to do.
I think there is a Problem with /dev/sdi, but thats not the only one.
Please have a look on this.

thx
Stefan

Code:

sudo mdadm --assemble /dev/md1 /dev/sda1 /dev/sdb1 /dev/sde1 /dev/sdf1 /dev/sdj1 -v
mdadm: looking for devices for /dev/md1
mdadm: /dev/sda1 is identified as a member of /dev/md1, slot 4.
mdadm: /dev/sdb1 is identified as a member of /dev/md1, slot 5.
mdadm: /dev/sde1 is identified as a member of /dev/md1, slot 0.
mdadm: /dev/sdf1 is identified as a member of /dev/md1, slot 1.
mdadm: /dev/sdj1 is identified as a member of /dev/md1, slot 2.
mdadm: added /dev/sde1 to /dev/md1 as 0 (possibly out of date)
mdadm: added /dev/sdf1 to /dev/md1 as 1 (possibly out of date)
mdadm: no uptodate device for slot 3 of /dev/md1
mdadm: added /dev/sda1 to /dev/md1 as 4
mdadm: added /dev/sdb1 to /dev/md1 as 5
mdadm: added /dev/sdj1 to /dev/md1 as 2
mdadm: /dev/md1 assembled from 3 drives - not enough to start the array.
