nodev,noatime,nobarrier,inode64 Ubuntu不支持nobarrier参数，因此，其XFS挂载参数为： rw,nodev,noatime,inode64 比如在/etc/fstab文件中的挂载配置为： /dev/sdc /data xfs nodev,noatime,nobarrier,inode64 0 0 确认 IO 寸文件时的性能更具优势，在RHEL和CentOS系统，使用如下的XFS挂载参数： rw,nodev,noatime,nobarrier,inode64 由于Ubuntu操作系统不支持nobarrier挂载参数，所以，使用如下的XFS挂载参数： rw,nodev,noatime,inode64 早些年的版本中，会提到一个挂载参数： allocsize=16M 注意：这个挂载参
