So you actually have five bad spots, two or three sectors apiece.

dd if=/dev/zero bs=1024 count=12 seek=1073006628 of=/dev/sdc1
dd if=/dev/zero bs=1024 count=12 seek=1073101016 of=/dev/sdc1
dd if=/dev/zero bs=1024 count=8 seek=1335739456 of=/dev/sdc1
dd if=/dev/zero bs=1024 count=8 seek=1346771164 of=/dev/sdc1
dd if=/dev/zero bs=1024 count=8 seek=1348581732 of=/dev/sdc1

One last check:  Did you run "badblocks /dev/sdc" or "badblocks
/dev/sdc1" ?

Phil

"/dev/sdc1"
history: "badblocks -v /dev/sdc1 -o /root/badblocks_sdc1.txt"

Very good.  So have you learned enough to be confident when you hit the
<enter> key?  :-)

now i boot my server with a live cd and recreate my raid.
if this was successfully i open the LUKS and check it.
here my commands for this step:
mdadm --create /dev/md2 --assume-clean --verbose --level=5 
--raid-devices=4 /dev/sdc1 /dev/sdd1 missing /dev/sdf1
cryptsetup luksOpen /dev/md2 md2_nas
fsck -n /dev/md2
