UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY

Problem

A CentOS VM was rebooted but failed to start with the following error:

/dev/mapper/VolGroup-lv_root: UNEXPECTED INCONSISTENCY; RUN fsck MANUALLY

sg1-fsck1

Solution

1)  Enter CLI

{Enter root password}

2) Run filesystem check . In my case.

# fsck -y /dev/mapper/VolGroup-lv_root

3 Reboot system

# reboot
