It's been an awful long time since I've ever needed to extend disk space, could someone please help me with a procedure.
I've added the disks to the SAN, and I've resized the LUN to +1TB
The machine "sees" the extra disk space.
Do I now need to increase the size of the physical volume (how?), then resize the logical volume, then resize the file system or am I supposed to add another physical volume, add the new PV to the volume group and then expand the logical volume and resize the file system.
