What doesgrep /home /etc/fstab
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?

What doesgrep /home /etc/fstab
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?

Have you recently migrated this partition to a new disk? Or resized existing partition(s) on the same disk? Looks to me like the the filesystem metadata isn't compatible with the underlying hardware, which would be consistent the hardware having changed for some reason (this is a perfectly legitimate thing to do - you just have to do it properly).
If you can afford to lose the data, I would simply mkfs /dev/VolGroup/lv_home
and be done with it.
Better would have been to shrink the filesystem before moving to a new volume, and then expanding it to fit - if it's not too late, do this.
Otherwise, if you want to keep the data, first thing is to take an image of the partition in case it goes wrong:
dd if=/dev/VolGroup/lv_home of=/var/tmp/home.img bs=65534
Next run the fsck again, but when you get the Interrupt?
, prompt say 'no' - you want to complete the fsck, not interrupt it. When it runs to completion, run fsck
again to be safe, and try to mount the drive then. Let us know how that goes.
import data all in the /home, but now can not mount it. whether there is way to get the data of it?

Use the dd command in the answer to create the image, then run fsck on it ('fsck /var/tmp/home.img'), then mount it ('mount /var/tmp/home.img /mnt'). All the contents of home should be visible under /mnt ('ls /mnt'). If it is, reformat your home partition ('mkfs /dev/VolGroup/lv_home'), mount it ('mount /dev/VolGroup/lv_home') and sync the contents from the image: ('rsync -a /mnt/ /home/'). Reboot and, if /home is working, you have successfully recovered and can now remove image.

What does
grep /home /etc/fstab
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?– Ed Grimm
