linux lvm创建文件系统
以下仅为安装记录
1、创建lv
2、创建挂载点
引用[root@Linux ~]# mkdir /dbra
3、直接挂载或用ext3格式挂载报错
引用[root@Linux ~]# mount /dev/VolGroup_ID_25519/lvdbra /dbra
mount: you must specify the filesystem type
[root@Linux ~]# mount -t ext3 /dev/VolGroup_ID_25519/lvdbra /dbra
mount: wrong fs type, bad option, bad superblock on /dev/VolGroup_ID_25519/lvdbra,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
4、用ext3文件系统格式lv
引用[root@Linux ~]# mkfs.ext3 -L lvdbra /dev/VolGroup_ID_25519/lvdbra
mke2fs 1.39 (29-May-2006)
Filesystem label=lvdbra
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
2621440 inodes, 5242880 blocks
262144 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=4294967296
160 block groups
32768 blocks per group, 32768 fragments per group

Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208,
4096000
Writing inode tables: done
Creating journal (32768 blocks): done
Writing superblocks and filesystem accounting information:
done
This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
5、mount挂载点
引用[root@Linux ~]# mount /dev/VolGroup_ID_25519/lvdbra /dbra
6、在/etc/fstab添加条目，随系统自启动
引用/dev/VolGroup_ID_25519/lvdbra /dbra ext3 defaults 1 2
