File system with errors.... Fedora 21 emergency mode, can't read itable bloc
I've been using fedora core 21 along with win 7 in dual-boot for a while now without any problem. Now, suddenly from yesterday, the fedora installation is booting into the emergency mode. It says that dev/mapper/fedora-usr contains a file system with errors, check forced. After the check, it prints out some ineligible data and goes to emergency mode, asks me for the password, tells me to type journalctl -xb for sys logs or to press ctrl-D to try booting into default mode. Journalctl-xb spits out around 9300 lines, some of which are red, and ctrl-D goes back again into the emergency mode.
The windows installation runs just fine by the way.
