Fixed, thanks Otto. I checked this drive and found an error of "BAD SUPER BLOCK: MAGIC NUMBER WRONG", it's fixed in the end. So I changed the last option of the fstab file from ZERO to TWO thus the command fsck can check it automatically. Thank you all for the great help, I am so happy my little NAS works again. The OpenBSD community is so helpful and there are so many nice people here, hopefully I can serve you all a cup of the tea I made from the mountain, actually I am making tea today.
