Tue Nov 22 16:27:22 UTC 2016

Did you install the drbd-pacemaker package? That’s the package that contains the resource agent.

Subject: [ClusterLabs] DRBD Insufficient Privileges Error

Hi,

I am trying to setup  two node H/A cluster with DRBD. Following is my configuration

[root at node-1 ~]# pcs config
Cluster Name: Cluster-1
Corosync Nodes:
node-1 node-2
Pacemaker Nodes:
node-1 node-2

Resources:
 Resource: vip (class=ocf provider=heartbeat type=IPaddr2)
  Attributes: ip=103.9.185.211 cidr_netmask=32
  Operations: start interval=0s timeout=20s (vip-start-interval-0s)
              stop interval=0s timeout=20s (vip-stop-interval-0s)
              monitor interval=30s (vip-monitor-interval-30s)
Resource: apache (class=ocf provider=heartbeat type=apache)
  Attributes: configfile=/etc/httpd/conf/httpd.conf statusurl=http://localhost/server-status
  Operations: start interval=0s timeout=40s (apache-start-interval-0s)
              stop interval=0s timeout=60s (apache-stop-interval-0s)
              monitor interval=1min (apache-monitor-interval-1min)
Master: StorageClone
  Meta Attrs: master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true
  Resource: storage (class=ocf provider=linbit type=drbd)
   Attributes: drbd_resource=drbd0
   Operations: start interval=0s timeout=240 (storage-start-interval-0s)
               promote interval=0s timeout=90 (storage-promote-interval-0s)
               demote interval=0s timeout=90 (storage-demote-interval-0s)
               stop interval=0s timeout=100 (storage-stop-interval-0s)
               monitor interval=60s (storage-monitor-interval-60s)

Stonith Devices:
Fencing Levels:

Location Constraints:
  Resource: apache
    Enabled on: node-1 (score:50) (id:location-apache-node-1-50)
Ordering Constraints:
  start vip then start apache (kind:Mandatory) (id:order-vip-apache-mandatory)
Colocation Constraints:
  vip with apache (score:INFINITY) (id:colocation-vip-apache-INFINITY)

Resources Defaults:
No defaults set
Operations Defaults:
No defaults set

Cluster Properties:
cluster-infrastructure: corosync
cluster-name: Cluster-1
dc-version: 1.1.13-10.el7_2.4-44eb2dd
have-watchdog: false
no-quorum-policy: ignore
stonith-enabled: false

The problem is I am getting insufficient privilege error on second node

[root at node-1 ~]# pcs status
Cluster name: PSD-1
Last updated: Mon Nov 21 01:44:52 2016          Last change: Mon Nov 21 01:19:17 2016 by root via cibadmin on node-1
Stack: corosync
Current DC: node-1 (version 1.1.13-10.el7_2.4-44eb2dd) - partition with quorum
2 nodes and 4 resources configured

Online: [ node-1 node-2 ]

Full list of resources:

vip    (ocf::heartbeat:IPaddr2):       Started node-1
apache (ocf::heartbeat:apache):        Started node-1
Master/Slave Set: StorageClone [storage]
     storage    (ocf::linbit:drbd):     FAILED node-2 (unmanaged)
     Masters: [ node-1 ]

Failed Actions:
* storage_stop_0 on node-2 'insufficient privileges' (4): call=16, status=complete, exitreason='none',
    last-rc-change='Mon Nov 21 01:19:17 2016', queued=0ms, exec=2ms

PCSD Status:
  node-1: Online
  node-2: Online

Daemon Status:
  corosync: active/disabled
  pacemaker: active/disabled
  pcsd: active/enabled

but DRBD seems okay for both nodes

  [root at node-1 ~]# drbd-overview
 0:drbd0/0  Connected Primary/Secondary UpToDate/UpToDate
 [root at node-2 ~]# drbd-overview
 0:drbd0/0  Connected Secondary/Primary UpToDate/UpToDate

Log of node2

Would appreciate any way out of this.

Thanks,
