Hi, please don't create new threads for the same topic. So it seems that 'rhel' is the name of the VG you're trying to activate, correct? To mount it you need to mount the path to the LV instead of the partition as I already wrote in my earlier response [1]. Try again with: mount /dev/rhel/root /mnt [1] http://lists.openstack.org/pipermail/openstack-discuss/2021-July/023807.html Zitat von KK CHN <kkchn.in@gmail.com>:

List,

I am in the process of uploading OS and data LVM disk image from ovirt(KVM) files fo our OpenStack Ussuri setup with KVM and glance.

I am able to upload the disk ( qcow2 images and profile the VM image). But I could not able to get the logical volume visible to the populated VM.

Here the data volume is LVM partition as another disk image handed over to us by our service provider.

here the steps I followed to get the LVM partition (/dev/vdc2) in question to get visible to our VM without success.

Kindly help to solve this issue.

How to make this /dev/vdc2(LVM partiton) attached to the VM. ?

Thank you, Kris
