 Posted: Tue Dec 12, 2006 7:02 pm Post subject: Mounting Linux LVM filesystem in Gentoo |
 |
|
Hi guys,
I am trying to mount a linux LVM filesystem in gentoo. I installed Fedora because I have to use it at work, so decided to play around with it at home, however I want to be able to access that file system from my gentoo installation.
I couldn't how to mount a Linux LVM in Gentoo.
I have two hard drives, /dev/hda and /dev/hdb of which hdb is the fedora distro.
/dev/hdb2 is the Linux LVM file system which I found out by fdisk.
Any help would be greatly appreciated.

Execute 'lvmdiskscan' and mount it from /dev/mapper.

Thanks, I think I'm heading in the right direction now but I'm a little stuck.
I ran lvmdiskscan which produced the following, however there is not /dev/mapper in /dev/.
Thanks
Paul

lvmdiskscan only scans for the drives, it does not activate them.
You’ll need name of the VolumeGroup. You can get it by invoking:
| Code: | | pvdisplay /dev/hdb2 |
(look for line beginning with VG)
To activate it invoke
| Code: | | vgchange -a y <VG_name> |
and all the devices should appear in /dev.
