I tried a few times to grow LVM by adding additional PV to VG, and then executing 'lvextend' command. I am not sure what I am doing wrong but I get the message that there is error locking on one of the nodes, and then the GFS hangs.
Here are some of the details:
[root@fenmrdev03 ~]# vgs

Command I tried:
[root@fenmrdev03 ~]# lvextend -l100%FREE /dev/nuvg4/nulv4
