独服的Linux根分区给化的太小了,怎么增容

steptodream

#查看根分区大小
[root@test ~]# df -h /
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       15G  1.1G   13G   8% /

#查看VG里还有多少空间
[root@test ~]# vgdisplay | grep Free
  Free  PE / Size       429 / 13.41 GB

#发现VG里还有10多G，所以给根分区所在的LV加10G
[root@test ~]# lvextend -L +10G /dev/mapper/VolGroup00-LogVol00
  Extending logical volume LogVol00 to 25.00 GB
  Logical volume LogVol00 successfully resized

#resize 文件系统size
[root@test ~]# resize2fs /dev/mapper/VolGroup00-LogVol00
resize2fs 1.39 (29-May-2006)
Filesystem at /dev/mapper/VolGroup00-LogVol00 is mounted on /; on-line resizing required
Performing an on-line resize of /dev/mapper/VolGroup00-LogVol00 to 6553600 (4k) blocks.
The filesystem on /dev/mapper/VolGroup00-LogVol00 is now 6553600 blocks long.

#再次查看 根分区已经从15G变成25G了
[root@test ~]# df -h /
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
                       25G  1.2G   23G   5% /
