Question

我想设置带有六个节点的corosync / pacemaker的多节点集群。节点有：WEB1 - WEB2，API1 - API2，DB1 - DB2。目前，我已经设置了DB节点（使用drbd进行FS复制，postgresql和DB_Virtual_IP）和API节点（仅限API_Virtual_IP）。

配置：

node api1
node api2
node db1 \
        attributes standby="off"
node db2 \
        attributes standby="off"
primitive api_vip ocf:heartbeat:IPaddr2 \
        params ip="API_IP_HERE" nic="eth0" iflabel="apivip" \
        op monitor interval="5"
primitive drbd_pg ocf:linbit:drbd \
        params drbd_resource="pg-claster" \
        op monitor interval="0" timeout="240" start \
        op stop interval="0" timeout="120"
primitive pg_fs ocf:heartbeat:Filesystem \
        params device="/dev/drbd0" directory="/data/pgdb" options="noatime,nodiratime" fstype="ext4" \
        op start interval="0" timeout="60" \
        op stop interval="0" timeout="120"
primitive pg_lsb lsb:postgresql \
        op monitor interval="30" timeout="60" \
        op start interval="0" timeout="60" \
        op stop interval="0" timeout="60"
primitive pg_vip ocf:heartbeat:IPaddr2 \
        params ip="DB_IP_HERE" nic="eth1" iflabel="pgvip" \
        op monitor interval="5"
group PGServer pg_fs pg_lsb pg_vip
ms ms_drbd_pg drbd_pg \
        meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1" notify="true"
location cli-prefer-PGServer PGServer \
        rule $id="cli-prefer-rule-PGServer" inf: #uname eq db1
location cli-prefer-api_vip api_vip \
        rule $id="cli-prefer-rule-api_vip" inf: #uname eq api1
location loc-drbd_pg_01 ms_drbd_pg -inf: api1
location loc-drbd_pg_02 ms_drbd_pg -inf: api2
location loc-pg_lsb-prim_01 pg_lsb -inf: api1
location loc-pg_lsb-prim_02 pg_lsb -inf: api2
location loc-pgserver_01 PGServer -inf: api1
location loc-pgserver_02 PGServer -inf: api2
location loc_api_vip_01 api_vip 100: api1
location loc_api_vip_02 api_vip 10: api2
location loc_api_vip_03 api_vip -inf: db1
location loc_api_vip_04 api_vip -inf: db2
colocation col_pg_drbd inf: PGServer ms_drbd_pg:Master
order ord_pg inf: ms_drbd_pg:promote PGServer:start
property $id="cib-bootstrap-options" \
        dc-version="1.1.7-ee0730e13d124c3d58f00016c3376a1de5323cff" \
        cluster-infrastructure="openais" \
        expected-quorum-votes="4" \
        stonith-enabled="false" \
        no-quorum-policy="ignore" \
        default-resource-stickiness="110"

使用此配置crm_mon打印“失败的操作：”：

Online: [ db1 db2 api2 api1 ]

 Master/Slave Set: ms_drbd_pg [drbd_pg]
     Masters: [ db1 ]
     Slaves: [ db2 ]
 Resource Group: PGServer
     pg_fs      (ocf::heartbeat:Filesystem):    Started db1
     pg_lsb     (lsb:postgresql):       Started db1
     pg_vip     (ocf::heartbeat:IPaddr2):       Started db1
api_vip (ocf::heartbeat:IPaddr2):       Started api1

Failed actions:
    pg_lsb_monitor_0 (node=api2, call=4, rc=5, status=complete): not installed
    drbd_pg:0_monitor_0 (node=api2, call=2, rc=5, status=complete): not installed
    pg_lsb_monitor_0 (node=api1, call=4, rc=5, status=complete): not installed
    drbd_pg:0_monitor_0 (node=api1, call=2, rc=5, status=complete): not installed

那么，这是正常情况，还是有一些其他参数来确定哪些节点资源可以运行和监控？

Answer 1

您在api1和api2上都缺少postgresql启动脚本，或者启动脚本具有不正确的权限或模式。检查两个节点上的postgresql启动脚本，然后运行'crm resource cleanup drbd_pg'

如何在多节点群集上设置资源
