ntfs-3g unmounts a disc one second after successfull mount

Hey Guys.

I have an Issue mounting an ntfs filesystem at system startup which is located on a fake-raid. For reference, here is the interesting section from journalctl: (read from buttom to top)

When you investigate the lines containing "ntfs-3g", you can see that the fs is first mounted properly and then unmounted without any error.
The reason for mounting the fs in a custom script is the following. The ntfs volume is on a fake-raid which is for some reason not detectable for dmraid or
mdadm. I managed to get the raid working, with a manual command which builds the raid with all parameters.
Essentialy, everything, reassembling the raid and then mounting the ntfs volume is working, if i do it manually.

I just wrote a script and a systemd unit to achieve task automatically on boot. But with this solution the explained is happening. (Its not a solution then right? )

So the question is. Do you have any ideas what the problem could be. Or do you have ways to gather more information about the difference between the manual and systemd approach?

Thx in advance Mates.

In Addition, here is the startscript and the systemd unit wich is calling it:

#!/bin/sh
# mount and assemble raid first. See scripts to see how.
echo "assemble"
/usr/local/bin/assemble_raid.sh
sleep 10

echo "mounting raid"
/usr/local/bin/mount_raid.sh

# after start the vms

echo "starting vms"
/usr/local/bin/start_windows_vm.sh

[Unit]
Description=Startup script launcher. Path : /usr/local/bin/my_startup.sh
Requires=multi-user.target
After=multi-user.target

[Service]
ExecStart=/usr/local/bin/my_startup.sh

[Install]
WantedBy=multi-user.target

Called scripts:

mount_raid.sh

#!/bin/sh
# script to asseble and mount the raid
mount -t ntfs-3g /dev/md1p1 /mnt/file-raid/

assemble_raid.sh

#!/bin/sh
# script to asseble and mount the raid

DEVS=$(blkid | grep 922CD0652CD045BF | grep -o -E "/dev/[^0-9]*" | tr "\n" " ")

echo "Building query with devs $DEVS"

mdadm --build --verbose /dev/md1 --level=1 --raid-devices=2 $DEVS
