Today I upgraded one of our KVM physical host servers to Centos 5.6. The other server remains on Centos 5.5. I've configured a storage pool in libvirt to use LUNs from an iscsi storage system as the volumes for each VM. After the upgrade, I decommisioned one of the VMs and removed the LUN from the storage system. Normally after this kind of operation, I simply need to run this command and the server will see that the LUN no longer exists and remove the volume. # virsh pool-refresh --pool=dev-kvm-storage Pool dev-kvm-storage refreshed This works fine on the centos 5.5 host, but the centos 5.6 still lists the old lun in the vol-list and displays zeros for the capacity. # virsh vol-info 7.0.0.26 --pool=dev-kvm-storage Name: 7.0.0.26 Type: block Capacity: 0.00 Allocation: 0.00 Do I need to do something different now for the newer version of libvirt that is included with centos 5.6? Here are the kernel and libvirt versions I'm using: Centos 5.6: kernel-2.6.18-238.9.1.el5 libvirt-0.8.2-15.el5_6.4 Centos 5.5: kernel-2.6.18-194.26.1.el5 libvirt-0.6.3-33.el5_5.3 Any help is greatly appreciated.
