Hi all,
I just performed a test which fail miserably. I have two nodes node-1 and node-2 Global file system /gfs is on node-1.
Two HA services running on node-1. If I unplug the cables for node 1 then those two services should transfers to Node-2. But node-2 did not take over the services. But if I do proper shutdown/reboot on node-1 then those two services are transferring to node-2 without problem.
Please Help!
clustat from node-2 before unplug of cable for node-1:
[root@Node-2 ~]# clustat Member Status: Quorate
Member Name ID Status ------ ---- ---- ------ Node-1 1 Online, rgmanager Node-2 2 Online, Local, rgmanager
Service Name Owner (Last) State ------- ---- ----- ------ ----- service:nfs Node-1 started service:ESS_HA Node-1 started
clustat from node-2 After unplug of cable for node-1:
[root@Node-2 ~]# clustat Member Status: Quorate
Member Name ID Status ------ ---- ---- ------ Node-1 1 Offline Node-2 2 Online, Local, rgmanager
Service Name Owner (Last) State ------- ---- ----- ------ ----- service:nfs Node-1 started service:ESS_HA Node-1 started
