[UCLA-LUG] Error in /dev/sda7

[MIng Yu]

Hi,

My linux ran perfectly till this Monday. It suddenly cannot boot up. The
error msg said:

checking root filesyste
/dev/sda7 contains a file system with errors, check forced.
/dev/sda7:
Inode 23271 has illegal blocks.
/dev/sda7: unexpected inconsistency; run fsck manually.

When I tried to run fsck, it said "Parallelizing fsck version 1.15".

I have no idea what's the problm since I'm new to linux. Can anyone help
me on this?

Thanks.
