I am running RHEL5. We have a volume group created with a SAN LUN as the backend storage. We are using multipathing to access this LUN. The storage admins have grown this LUN on their end. I would like to discover the new LUN size and add the available space to the existing volume group through LVM. I would prefer to do it without rebooting.
I found a similar post here: http://www.linuxquestions.org/questi...growth-873345/
Would I be able to follow the 2nd posts' instructions in order to do this without a reboot? I don't believe we have any partitions set up as the whole LUN is assigned to 1 volume group, which contains 1 logical volume.
Rather than using the extendlv command, I should be able to use the LVM GUI to edit the LV and "Use remaining" space, correct?
