About detect and mount extend/LVM partitions

[satimis]

Hi folks,


My HD has extend partition and LVM. Is there any way to detect and mount them.

# fdisk -l

Disk /dev/sda: 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/sda1   *           1          31      248976   83  Linux
/dev/sda2              32       19457   156039345    5  Extended
/dev/sda5              32       19457   156039313+  8e  Linux LVM

sda1 is mounted automatically with its icon displayed on desktop.

# ls -al /media/sda1

# ls /media/

cdrom0  floppy0  sda1  sda5

sda5 seems mounted as well.


# ls -al /media/sda5

total 2
drwxr-xr-x 2 root root 1024 Aug 29 06:14 .
drwxr-xr-x 6 root root 1024 Aug 29 06:14 ..

But nothing found on it.

Advice would be appreciated. TIA

It is probably not an issue anymore, so it is just for posterity.

I found good answer at: http://www.linuxquestions.org/questi...noppix-471366/

Here is summary how to mount LVM disks:
knoppix# vgscan --mknodes
Reading all physical volumes. This may take a while...
Found volume group "system" using metadata type lvm2
# vgchange -ay
3 logical volume(s) in volume group "system" now active
# lvscan
ACTIVE '/dev/system/home' [20.00 GB] inherit
ACTIVE '/dev/system/root' [15.00 GB] inherit
ACTIVE '/dev/system/swap' [2.00 GB] inherit
# mkdir -p /mnt/root /mnt/home
# mount /dev/system/root /mnt/root
# mount /dev/system/home /mnt/home

More about LVM is on:

Hope it helps to the next person.
