Filesystem mounts read only during reboot [solved]

Question

Hi folks,
after shredding my last Arch installation I'm trying to set everything up again using the new released image.
generating the /etc/fstab file by
genfstab -p /mnt >> /mnt/etc/fstab
creates the following code:
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
tmpfs /tmp tmpfs nodev,nosuid 0 0
# UUID=6c76fc7c-45d9-43e5-8530-7d098a58ca76
/dev/sdb3 / ext4 rw,relatime,data=ordered 0 1
# UUID=8ac179e7-b291-440a-839c-0fd476abcf1c
/dev/sdb2 /boot ext2 rw,relatime 0 2
after rebooting I get the message:
fsck.ext4: No such file or directory while trying to open /dev/sdb3
Possibly non-existent device?
and my file-system is mounted as read-only.
after changing the /etc/fstab by gaining rw-access using "mount -o remount,rw /" to
# /etc/fstab: static file system information
# <file system> <dir> <type> <options> <dump> <pass>
tmpfs /tmp tmpfs nodev,nosuid 0 0
I once again get the file-system mounted as read-only. I would appreciate your suggestions on how to get rw-Access each reboot.

Answer 1

I'm sorry for that confusion, I copied the partition table by hand and mixed that up. It is always /dev/sdb.
Edit: just corrected that in the first post
You are right
