Topic : lvm.conf

Posted By: mitgib on March 23, 2015, 2:26 am

Noticed this after I migrated a KVM container which was using LVM, on Ubunt14.04 LTS for the host node, /etc/lvm/lvm.conf needs the following modified to prevent the host OS from freaking out

Code

    # By default we accept every block device:

    filter = [ "a/sda/", "r/.*/" ]

This node only has a /dev/sda block device, but edit as needed if you have more than a single block device

Hi,

Can you please elaborate what issue you faced after migration from ubuntu which were resolved after changing the lvm.conf ?
As these changes are not required.

I added this based on my configuration of OpenStack as detailed here http://docs.openstack.org/juno/install-guide/install/apt/content/cinder-install-storage-node.html

This advice is given for Ubuntu and RHEL, so it is not ubuntu specific. See step 8

I've added this to Virtualizor as preventative. Users who have access to ISO images will do whatever is available, so I cannot expect them not to use LVM within their containers.
