elrepo-kernel

The elrepo-kernel channel provides both the long-term support kernels (which have been configured for RHEL-6 and RHEL-5) and the latest stable mainline kernels (which have been configured for RHEL-7 and RHEL-6) using sources available from the Linux Kernel Archives (external link). Please see the kernel-lt or kernel-ml pages for further details. This channel may be enabled in the /etc/yum.repos.d/elrepo.repo file or used with ‘yum –enablerepo=elrepo-kernel’.

yum –enablerepo=elrepo-kernel -y install kernel-ml

yum –enablerepo=elrepo-kernel -y install kernel-lt

.安装ext4

yum -y install e4fsprogs

.格式化分区成ext4

mkfs.ext4 /dev/sdb1

.加载

mount -t ext4 -o noatime /dev/sdb1 /data

.把现有ext3分区以ext4格式加载

mount -t ext4dev -o remount,noatime /dev/sdb1

.把现有分区修改成ext4 ( /dev/sda1 on /boot type ext3 (rw) [/boot] )

tune4fs -O extents,uninit_bg,dir_index,flex_bg /dev/sdb1
e4fsck /dev/sda1

.编辑/etc/fstab

/dev/VolGroup00/LogVol00   /   ext4dev  defaults.noatime  1   1
echo "/dev/sdb1  /data   ext4  noatime  0  0" >> /etc/fstab
