How do I mount existing Fedora LVM after new Kubuntu install?
 
Hi,
I have a 500gb hdd with xp, and fedora8 installed. There are 170+gb free space after those two. I installed Kubuntu here.

I assumed that Kubuntu would edit grub to include kubuntu, xp as well as fedora, but it only does kubuntu and xp.

Unfortunately, the Fedora8 was installed as LVM, but all my files are here and want to be able to transfer betweed the kubuntu and fedora partitions.

I tried to make sure Kubuntu wasn't touching the LVM partition during install, but when I go to kmenu> System Settings> Advanced> Disk & Filesystems It's showing what should be a Fedora LVM as a mount point of /proc. What does this mean? There's nowhere to change that and I'm not sure I want to risk it.


fdisk -l shows this:


Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

/dev/sda7 39424 60801 171718753+ 83 Linux


fstab has this (looks like my windows partitions and my optical drive.)

# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc defaults 0 0
# /dev/sda7

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec 0 0


I've thought about just adding /dev/sda5 to fstab but how do I find out its UUID?

This is getting frustrating.

Help me out guys. I need those files off my LVM.

I can post grub's menu.lst from pre and post Kubuntu if needed 'cause I can kept copies before I did the install.

So far I like Anaconda LOTS better.

Any thoughts?

Since the LVM is present as a partition, try these steps

# pvscan
# vgscan
# vgchange -a y

After this the logical volumes must be visible. Try mouting them and getting the data

After the command of vgchange, you must get some information on the numberof logical volumes which got activated.

Hi!
Sorry, I've taken so long to reply.
I tried those commands. Here is what they displayed.

Quote:

pvscan
No matching physical volumes found
Quote:

vgscan
Reading all physical volumes. This may take a while...
No volume groups found
Quote:

vgchange -a y
No volume groups found
Is this because the LVM isn't in fstab?

... or am I doing something wrong?

Thanks for your help!

Thanq you!

This solved my problems. I got the following:

[root@Loke ~]# pvscan
PV /dev/sdc1 VG datadisc lvm2 [698,64 GB / 0 free]
PV /dev/sdb1 VG datadisc lvm2 [698,64 GB / 0 free]
PV /dev/dm-0 VG VolGroup00 lvm2 [148,84 GB / 32,00 MB free]
[root@Loke ~]# vgscan
Reading all physical volumes. This may take a while...
Found volume group "datadisc" using metadata type lvm2
Found volume group "VolGroup00" using metadata type lvm2
[root@Loke ~]# vgchange -a y
1 logical volume(s) in volume group "datadisc" now active
2 logical volume(s) in volume group "VolGroup00" now active

after that I mounted the device manually:
[root@Loke ~]# mount -t ext3 /dev/datadisc/LogDatadisc /home/<my home dir>/dl/

when it worked I edited /etc/fstab with the new mounting point.

Those commands results are what happen when you run those commands with user of not high enough privileges (root user).

Either use sudo in front of each command, or su - to login as root user.

If you want some LVM notes and tips see my wiki: http://nickyeates.com/technology/uni...filesystem_lvm

THANKS bhaslinux and thanquol!!! You helped solve a 1.5 year long problem of data being stuck on some drives of mine. I had made the LVM2 group with EVMS a few years back, and all a sudden EVMS didnt know how to mount it anymore. EVMS was a graphical raid and LVM creation utility, that has since gone under. Luckily these commands brought it right up!

Code:

pvscan
pvdisplay (physical volume display)
vgdisplay (volume group display)
lgdisplay (logical group display)

Code:

root@lms:~# vgscan
  Reading all physical volumes.  This may take a while...
  Found volume group "Media" using metadata type lvm2

root@lms:~# vgchange -a y
  1 logical volume(s) in volume group "Media" now active

Saw in file listings of /dev/Media/ and /dev/mapper/ that devices existed!

Code:

root@lms:/dev/mapper# mkdir /media/olddocuments
root@lms:/dev/mapper# mount -t ext3 /dev/Media/CargoPlane /media/olddocuments/
