在我们应用电脑的时候，我们是否了解电脑是怎样运行的？其实在电脑中操作系统必不可少，现在很多电脑用户都在应用Linux操作系统，Linux的发展也非常迅速。这里介绍Linux扩展文件系统的知识，希望你记住Linux扩展文件系统方法。
将新增的磁盘建成pv
[root@oracle11g dev]# pvcreate /dev/sdb
- 1.
扩展vg，将新的pv加进vg中
[root@oracle11g dev]# vgextend VolGroup01 /dev/sdb
Volume group "VolGroup01" successfully extended
- 1.
- 2.
将要扩展的文件系统先卸载下来
[root@oracle11g dev]# umount /oracle
- 1.
扩展lv
[root@oracle11g dev]# lvextend -L 6.5G /dev/VolGroup01/LogVol01
Extending logical volume LogVol01 to 6.50 GB
Logical volume LogVol01 successfully resized
- 1.
- 2.
- 3.
需要先校验一下
[root@oracle11g sysconfig]# resize2fs /dev/mapper/VolGroup01-LogVol01 6G
resize2fs 1.35 (28-Feb-2004)
Please run 'e2fsck -f /dev/mapper/VolGroup01-LogVol01' first.
[root@oracle11g sysconfig]# e2fsck -f /dev/mapper/VolGroup01-LogVol01
e2fsck 1.35 (28-Feb-2004)
Pass 1: Checking inodes, blocks, and sizes
Pass 2: Checking directory structure
Pass 3: Checking directory connectivity
Pass 4: Checking reference counts
Pass 5: Checking group summary information
/dev/mapper/VolGroup01-LogVol01: 42302/631488 files (0.9% non-contiguous), 888327/1261568 blocks
- 1.
- 2.
- 3.
- 4.
- 5.
- 6.
- 7.
- 8.
- 9.
- 10.
- 11.
再扩展文件系统
[root@oracle11g sysconfig]# resize2fs /dev/mapper/VolGroup01-LogVol01 6G
resize2fs 1.35 (28-Feb-2004)
Resizing the filesystem on /dev/mapper/VolGroup01-LogVol01 to 1572864 (4k) blocks.
The filesystem on /dev/mapper/VolGroup01-LogVol01 is now 1572864 blocks long.
- 1.
- 2.
- 3.
- 4.
将文件系统mount上。
[root@oracle11g sysconfig]# mount –a
- 1.
查看
[root@oracle11g sysconfig]# df -h /oracle
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup01-LogVol01
6.0G 3.4G 2.4G 59% /oracle
- 1.
- 2.
- 3.
- 4.
