[ovirt-users] expanding a master lun storage domain on the san side

[Nathanaël Blanchet]

Hello,

Since I can live migrate the storage to another lun so as to put the 
master domain in maintenance, it is quite very long (2,5To) and I will 
have to do the same in the other side.
Is it a risk to Resize the relevant PV without putting the domain in 
maintenance?
In my memory, it is not a risk to expand a physical volume while it not 
recommended to shrink the volume...
