Hey there,

Could you describe the steps for expanding the LUN? From expanding on IBM
to resizing the disk on oVirt.
I don't work with IBM, but I believe it is similar to HP, Infortrend,
Dell... Is your IBM Storage FCP or iSCSI?

Can you identify if the LUN has been expanded on the host, using the
multipath -ll command?
