LVM---动态调整磁盘容量

Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 35 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.

备注：也可通过 [root@RHEL5 /]# mkfs.ext3 /dev/vg01/data 格式化

3）使用lvsacn查看逻辑卷的信息
[root@RHEL5 /]# lvscan #查看逻辑卷的信息
ACTIVE ''/dev/vg01/data'' [6.00 GB] inherit
ACTIVE ''/dev/VolGroup00/LogVol00'' [38.88 GB] inherit
ACTIVE ''/dev/VolGroup00/LogVol01'' [1.00 GB] inherit

4）使用lvdisplay查看逻辑卷的具体参数：
[root@RHEL5 /]# lvdisplay #查看逻辑卷的具体参数
