It would be simpler to add a LUN to the OS and then add that to the volume group. You can then work with the filesystems cleanly, even if they are mounted. Is there a reason you cannot allocate another LUN to the virtual server? I'm told by our VMWare man that we have a limited number of LUNs he can attach.
If you are trying to keep it simple for neatness, could you add a much larger LUN, add it to the volume group, use pvmove to migrate the data from the existing LUN to the new one and release the old LUN? That way you will end up with the same number of LUNs attached.

This is actually a VxVM question. I have a volume/filesystem spread over 4*146G disks. Now I want to shrink the filesystem - which I can do using vxresize. However, I want to shrink so that two of the four disks that the filesystem occupies are removed from the volume. Can I do that? (3 Replies)
