i dont know what chunk do you what but i think you mean 512k
Yes.

WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util
fdisk doesn't support GPT. Use GNU Parted.
Oops. But you get the point, I hope. /dev/sdc has a different
partition table from /dev/sdb and /dev/sde. That short partition is
causing mdadm to make the array too small for the filesystem in it.
You need to fix the partitions on /dev/sdc to exactly match /dev/sdb and
/dev/sde. Can you explain how it might have become different?
And use "parted /dev/sdb print" to show the partitions instead of fdisk.

no i have no idea why die partion table is wrong on /dev/sdc.
i can copy with dd the partion table from sdb to sdc...
example:
dd if=/dev/sdb of=sdb.part bs=512 count=1
dd if=sdb.part of=/dev/sdc bs=512 count=1
