I have 2 harddisk, the first hdd (80 GB) is an empty hdd that i have already installed with new ubuntu server and the other one is an old hdd(180 GB) consist of ubuntu with LVM system. And i am trying to add the oll hdd to my cpu. Here is the 2 hdd detail<\/p>\n

As you can see the old hdd ( 160 GB) \/dev\/sdb1 have LINUX LVM , you need lvm2 so you can mount it, here is the step<\/p>\n
#apt-get install lvm2<\/p>\n
You need to use pvs command to determine the volume group containing the physical volume \/dev\/sdb1<\/p>\n
# pvs<\/p>\n

You can see there are physical volume named test onsecond hdd \/dev\/sdb1<\/p>\n

As you can see there are 2 lvm \/dev\/test\/swap_1 and \/dev\/test\/root that actual shortcut from \/dev\/mapper\/test-swap_1 and \/dev\/mapper\/test-root<\/p>\n
Now you just need to mount the \/dev\/testroot to directory you wanted , let say \/mnt\/oldhdd<\/p>\n
# mkdir \/mnt\/oldhdd<\/p>\n
# mount \/dev\/test\/root \/mnt\/oldhd\/<\/p>\n
you can see the mount now<\/p>\n
