[Pacemaker] cibadmin set node offline?

[James Gibbard]

Hi,

I have setup a 2 node cluster, using the following packages:

pacemaker                           1.1.10+git20130802-1ubuntu2
corosync                            2.3.3-1ubuntu1

My cluster config is as so:

node $id="12303" ldb03
node $id="12304" ldb04
primitive p_fence_ldb03 stonith:external/vcenter \
        params VI_SERVER="10.17.248.10"

        op start interval="0" timeout="500s"
primitive p_fence_ldb04 stonith:external/vcenter \
        params VI_SERVER="10.17.248.10"

        op stop interval="0" timeout="120" \
        op monitor interval="20" timeout="30" \
        meta target-role="Started" is-managed="true"

        last-lrm-refresh="1407325251"


This exact configuration has worked during the setup, but I have
encountered a problem with my inactive node ldb03. Corosync shows this node
as up:

root at ldb03:~# corosync-cmapctl | grep members
runtime.totem.pg.mrp.srp.members.12303.config_version (u64) = 0
runtime.totem.pg.mrp.srp.members.12303.ip (str) = r(0) ip(10.10.10.8)
runtime.totem.pg.mrp.srp.members.12303.join_count (u32) = 1
runtime.totem.pg.mrp.srp.members.12303.status (str) = joined
runtime.totem.pg.mrp.srp.members.12304.config_version (u64) = 0
runtime.totem.pg.mrp.srp.members.12304.ip (str) = r(0) ip(10.10.10.9)
runtime.totem.pg.mrp.srp.members.12304.join_count (u32) = 1
runtime.totem.pg.mrp.srp.members.12304.status (str) = joined

and crm status and crm node status show it as online:

Last change: Wed Aug  6 14:02:00 2014 via crm_resource on ldb04
Stack: corosync
Current DC: ldb04 (12304) - partition with quorum
Version: 1.1.10-42f2063
2 Nodes configured
7 Resources configured
Online: [ ldb03 ldb04 ]

root at ldb03:~# crm node status
<nodes>
  <node id="12304" uname="ldb04"/>
  <node id="12303" uname="ldb03"/>
</nodes>


but....after seeing this entry in my logs:
Aug  6 13:26:23 ldb03 cibadmin[2140]:   notice: crm_log_args: Invoked:
cibadmin -M -c -o status --xml-text <node_state id="ldb03" uname="ldb03"
ha="active" in_ccm="false" crmd="offline" join="member" expected="down"
crm-debug-origin="manual_clear" shutdown="0"/>

I noticed that cibadmin shows it as normal(offline)
root at ldb03:~# crm node show
ldb04(12304): normal
ldb03(12303): normal(offline)

The offline state is not present in anything but cibadmin. Not the cib.xml,
not corosync-quorumtool and a tcpdump shows multicast traffic from both
hosts.

I tried (hesitantly) to delete the line using cibadmin, but I couldn't
quite get the syntax right. Any tips on how to get this node to show as
online and subsequently be able to run resources? Currently, when I run crm
resource move, this has no effect, no errors and nothing noticeable in the
logfiles either.

Sorry for long thread....I can attach more logs/config if necessary.

Thanks,

Jamie.
