pvs is:

PV VG Fmt Attr PSize PFree
/dev/sda3 centos lvm2 a-- <3.64t 4.00m

and also these file attached!!! ::: fdisk -l_txt, lvs.txt, cat /etc/fstab_txt
please check these files to fix my problem!!

I suspect you have an error in your /etc/fstab for /data as it is refusing to mount. Edit that file and comment the line out and reboot to see if that helps. Next time you modify that file, umount the new filesystem you added to it and run mount -a which will syntax check it and mount anything that isn't mounted that should be.

thanks a lot!!!
as you advised, i edited /etc/fstab to '/dev/sda /data ext4 defaults 1 2'
means /dev/sdb to /dev/sba
then, normally succeed to boot on, thanx again....
