CentOS

i need to go to save my files there,, this journal in attached

If you removed a disk and are now entering emergency mode at boot then it sounds like you forgot to remove all filesystems from /etc/fstab that refer to them. Boot into emergency mode then hit Ctrl-D to exit it and boot uup. Now edit /etc/fstab and see what is in there that no longer exists, comment it out and reboot again.
