1、将上个实验中的逻辑卷vo扩展至290M：[root@linuxprobe ~]# lvextend -L 290M /dev/storage/voRounding size to boundary between physical extents: 292.00 MiBExtending logical volume vo to 292.00 MiBLogical volume vo successfully resized
2、检查磁盘完整性，重置硬盘容量：[root@linuxprobe ~觥终柯计]# e2fsck -f /dev/storage/voe2fsck 1.42.9 (28-Dec-2013)Pass 1多唉捋胝: Checking inodes, blocks, and sizesPass 2: Checking directory structurePass 3: Checking directory connectivityPass 4: Checking reference countsPass 5: Checking group summary information/dev/storage/vo: 11/38000 files (0.0% non-contiguous), 10453/151552 blocks [root@linuxprobe ~]# resize2fs /dev/storage/voresize2fs 1.42.9 (28-Dec-2013)Resizing the filesystem on /dev/storage/vo to 299008 (1k) blocks.The filesystem on /dev/storage/vo is now 299008 blocks long.
3、重新挂载硬盘设备并查看挂载状态：[root@linuxprobe ~]# mount -a[root@linuxprobe ~]# df -hFilesystem Size Used Avail Use% Mounted on/dev/mapper/rhel-root 18G 3.0G 15G 17% /devtmpfs 985M 0 985M 0% /devtmpfs 994M 80K 994M 1% /dev/shmtmpfs 994M 8.8M 986M 1% /runtmpfs 994M 0 994M 0% /sys/fs/cgroup/dev/sr0 3.5G 3.5G 0 100% /media/cdrom/dev/sda1 497M 119M 379M 24% /boot/dev/mapper/storage-vo 279M 2.1M 259M 1% /linuxprobe
