[Linux-cluster] mounting a replicated lun

[Paras pradhan]

So what I understand overall is, I assign this new lun to all cluster nodes
, remove the orignal lun from all cluster nodes and since the lun has lvm
and I don't need the original lun , I don't need to worry about
vgiimport(changing the vg name) . right?

Thanks
Paras.
