When I mount my /dev/VolGroup/lv_home
there get error:
[root@localhost VolGroup]# mount /dev/VolGroup/lv_home /home/

output? Are you absolutely certain that /dev/mapper/VolGroup-lv_home was an ext4 partition? I understand it resembled one enough that fsck -t ext4 didn't refuse to operate on it, but that's not necessarily a guarantee that it was an ext4. Also, how did this get in this state? Did it just start happening one boot, was it a bad shutdown, a power spike (includes lightning strikes), a drink spill, earthquake, or something else?
