fedora and ubuntu file system

[pom]

I have two HDDs on my desktop, 250GB has old fedora with all my files, and the 800GB has Ubuntu 9.10, brand new, no data. I booted into Ubuntu and it sees the 250GB drive but got error when mount the drive, something about LVM2 file system. I search the web and found that I need to re-partition Ubuntu side to LVM, which as I understand will be a new install.

Question: Can someone suggest an easiest way to copy all my files from Fedora side (/dev/sda disk) onto Ubuntu disk (/dev/sdb)?

thanks

Mounting a Linux LVM volume

thanks for your note.
I can not simply mount Ubuntu on the LVM file system.

I will go back to Fedora.

please considered this issue close for me, thanks

Hi,

I think you will be more than happy with Ubuntu. It is better than Fedora as far as packages and ease of use is concerned. For the LVM issue, you should try the methos given by coopstah13. It should work.

O.k. This is what I have from fdisk -l

fdisk -l

Disk /dev/sda: 250.0 GB, 250000000000 bytes

/dev/sdb2 64 97282 780898304 8e Linux LVM

when I try to mount using

"mount /dev/sdb2 /media/800GB"
mount: you must specify the filesystem type

So what file system? How can I find out?

[yancek]

"mount /dev/sdb2 /media/800GB"

This site explains a lot about Ubuntu 9.10 and is worth a read if you are using it. By defaul, it uses ext4 filesystem type so, unless you changed it during the install, the following command should work. You will have to have created the directory 800GB in the /media directory for it to work:

mount -t ext4 /dev/sdb2 /media/800GB

read my previous post on how to mount LVM!!

[pom]

Dear coopstah13,

I am afraid I do not know what command to use to mount LVM volume, per your
broad answer.

Per Yancek, his suggestion does not work either.

[root@PomLinux ~]# mount -t ext4 /dev/sdb2 /media/800GB
mount: unknown filesystem type 'ext4'

and that is why I posted in another post asking how to check file system.

thanks

first log in as root
then type the following commands
#lvscan
#pvscan

then identify your volumegroup correctly. it should be there in /dev/......
in the future commands replace /dev/logical-volume by whatever logical volume that your volume group is

then
#vgchange /dev/volumegroup -a y

after this you will be able to mount your filesystem
