We configure cluster with rhcs with storage partition.we created pv and vg. we can see pvdisplay and vgdisplay with all information about pv and vg which we created.
But we can not see vg file on /dev , /dev/mapper and therefore not able to format it and use.
please suggest to resolve this problem.
