我的机器两个硬盘,一个80g的做的lvm
是我从别的机器上拿下来的,上面有数据.我想在我现在的系统上挂载它,可不行,高人给点指点!!!!!!
[root@all /]# fdisk

[root@all
/]# mount /dev/hdc2 /mnt/cdrom
mount: you must specify the
filesystem type
mount 时出线上面的错误!谁给点提示!谢谢!
回答:
1.先用vgscan
2.vgchange -ay
3.lvscan
4.mount
到第三步的时候如果正常会显示出两块硬盘的lv状态都是active,此时再
#mount -t ext3 /dev/VGname/LVname /mnt/cdrom
就可以成功了。
