Raid FS can't mount

Yesterday I had a Error to write Data to my Filesystem. After reboot the Share “Allgemein” on a Raid 5 isn’t avaible.
I could’t boot from the actual Version Linux-4.8.7, I have to fall back to 4.6.0.
I need help, e2fsck/ fsck.ext4 dosn’t help
can I mount in Commandline this Share once, it could help to save my files.
some Error in the dmesg
