By default CentOS 7 uses the xfs filesystem. The utility debugfs will not work for filesystems other than ext2/ext3/ext4

If the file is still opened by a process you can restore the file using the open filedescriptor:

lsof |egrep "COMMAND|keystone.conf.disabled"
cp /proc/<pid>/fd/### /var/tmp/keystone.conf.disabled
