mounting a fedora LVM from Ubuntu

cerealdaemon · 04-20-2006, 08:58 PM

I installed Fedora 4 to an LVM across two 60 gig disks, but I don't know the syntax to mount that to a seperate Ubuntu install on a different disk. Data and whatnot are on the fedora install, and to the best of my knowledge, you can't just mount a single drive of an LVM and get a drive with useable data.

root@Akona:/home/zack# /sbin/fdisk -l

You can't just mount an lv.

if your ubuntu has lvm installed you can try the following ( as root! )

Code:

vgscan (say your volumegroup is VolGroup00)
vgchange -ay VolGroup00
lvs (check which name the fedora root filesystem has, say /dev/VolGroup00/LogVol00)
cd /mnt
mkdir fedora_root
mount /dev/VolGroup00/LogVol00 fedora_root

This should mount your fedora root filesystem on /mnt/fedora_root. You will have to fill in the blanks, that's all.

Hope this helps?

if the commands 'vgscan' and 'vgchange' don't exist, you can try it with preceding them with 'lvm', so they will be: 'lvm vgscan' and 'lvm vgchange -ay'

how do I install lvm on ubuntu?

I am not familiar with ubuntu, so I cannot answer that question.

Don't you have the package lvm2 installed (as root, isn't the command lvm available) ?

I got the lcm command working, but I don't know where to go from there. How do I pull the data off of the lvm onto the other hard drive using the lvm command?

The commands I provided in my first response can be preceeded with the lvm command (for example 'vgchange -ay' can also be achieved with: 'lvm vgchange -ay'.

Try the list of commands I replied above to see if you can get any further...?
