Isn't that more likely to be something like /dev/sdc1 ? 

What's in /etc/fstab ?

THANK YOU!!! But there is an error in command xfs_growfs. I try this command
# xfs_growfs /dev/sdc then an error comes out.

xfs_growfs: /dev/sdc is not a filesystem mount point, according to /etc/mtab

Thanks alot.

xfs_growfs to make it fit the new partition size.
