[Linux-cluster] Cluster and LVG/LV

[Chris Edwards]

Yes to both.  Right now the cluster is running GFS and I can migrate VM's between the nodes.

This question is coming up because I have been trying to do a snap shot and I realized the snapshot is stored on the Volume Group that the LV is located on.  I did not realize  this and I cannot do a snapshot because I did not leave enough space in each of the Volume Groups for each of the VM's.

Chris,

Are you running a clustered LVM, and do you expect to be able to use Xen migration?

Jeff

If I am installing multiple Xen VM's in a cluster with shared iSCSI space with Logical Volumes for each virtual machine should I put each LV in its own logical volume group or should I use one logical volume group for all of the LV's?

Thanks!
