[SOLVED] How to fix filesystem error

[Ex_Soft]

During each boot the recovery console is appeared.

/dev/mapper/VolGroup-lv_root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY.
(i.e., without -a or -p options)
dracut Warning: e2fsck returned with 4
dracut Warning: /dev/mapper/VolGroup-lv_root contains a file system with errors, check forced.
dracut Warning: /dev/mapper/VolGroup-lv_root: Inodes that were part of a corrupted orphan linked list found.

1) Copy original to backup
2) Copy backup to original
3) No action

I've tried all items but nothing happened.

Leaving file system unchanged.

/dev/sda3 is mounted.

WARNING!!! The filesystem is mounted. If you continue you ***WILL***
cause ***SEVERE*** filesystem damage.

Do you really want to continue<n>? no
check aborted.

When I leave the recovery console I can normally boot.

How to fix errors?

fsck /dev/mapper/VolGroup-lv_root

has solved my problem

[DBelton]

your root (/) filesystem is in /dev/sda4 but you can't specify /dev/sda4 since it's not a filesystem but a logical volume. You need to specify the logical partition name instead.

try running:

e2fsck /dev/mapper/VolGroup-lv_root
