You do not mount a partition of type "Linux LVM" the same way you mount a partition using a standard Linux file system (e.g. ext2, ext3).
如果连root都不能写的话,就不是权限的问题。
首先确定,hda2是不是ntfs或者什么新型的分区。
如果是的话,确实是不能写入的,ntfs可以打开写入功能,但是相当危险,绝对不推荐。
如果不是,你只要在挂上以后执行:
mount -o remount,rw /mnt/e
或者挂载的时候就执行:
mount -o rw /dev/hda2 /mnt/e
就可以了。
# fdisk -l /dev/hda
Disk /dev/hda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 19457 156183930 8e Linux LVM
# mount /dev/hda2 /tmp/mnt
mount: /dev/hda2 already mounted or /tmp/mnt busy
First, let's determine the volume group containing the physical volume /dev/hda2.
# pvs
PV VG Fmt Attr PSize PFree
/dev/hda2 VolGroup01 lvm2 a- 148.94G 32.00M
/dev/hdb2 VolGroup00 lvm2 a- 114.94G 96.00M
Next, let's list the logical volumes in VolGroup01.
# lvdisplay /dev/VolGroup01
--- Logical volume ---
LV Name /dev/VolGroup01/LogVol00
VG Name VolGroup01
LV UUID zOQogm-G8I7-a4WC-T7KI-AhWe-Ex3Y-JVzFcR
LV Write Access read/write
LV Status available
# open 0
LV Size 146.97 GB
Current LE 4703
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:2
--- Logical volume ---
LV Name /dev/VolGroup01/LogVol01
VG Name VolGroup01
LV UUID araUBI-4eer-uh5L-Dvnr-3bI6-4gYg-APgYy2
LV Write Access read/write
LV Status available
# open 0
LV Size 1.94 GB
Current LE 62
Segments 1
Allocation inherit
Read ahead sectors 0
Block device 253:3
The logical volume I would like to "mount" (in purely the computing-related sense) is /dev/VolGroup01/LogVol00. The other logical volume is a swap partition.
# mount /dev/VolGroup01/LogVol00 /tmp/mnt
lvm挂载(mount)处理方式

以前特别怕服务器用lvm的方式分区,文档里面都特别要求机房要装ext3分区的,就是因为lvm格式不知道怎么处理,后来仔细想想,没道理后面出的文件系统会比老的系统更难用,这会刚好有个lvm的分区格式的机器在手上,花了一些时间,终于整好了lvm挂载的正确方法:
对LVM分区进行挂载,三步曲,探测到,然后激活,再挂载。
1. 探测VolGroup
#vgscan
2. 激活
# vgchange -a y VolGroup00
3. 挂载
#mount /dev/VolGroup00/LogVol01 /mnt/hdb2
注:按实际情况 ls一下/dev/Vol*
