Pacemakerの設定を保存したり、読み込んだりするためのメモです。
以下のように、すでにクラスター構成が出来ている状態とします。
[root@db01 ~]# pcs status Cluster name: drbd_cluster WARNINGS: Corosync and pacemaker node names do not match (IPs used in setup?) Stack: corosync Current DC: db01 (version 1.1.21-1.el7-f14e36f) - partition with quorum Last updated: Tue Jun 9 20:16:52 2020 Last change: Tue Jun 9 15:38:50 2020 by root via cibadmin on db02 2 nodes configured 6 resources configured Online: [ db01 db02 ] Full list of resources: Resource Group: Group-FS FS (ocf::heartbeat:Filesystem): Started db01 vipcheck (ocf::heartbeat:VIPcheck): Started db01 VIP (ocf::heartbeat:IPaddr2): Started db01 prmPing (ocf::pacemaker:ping): Started db01 OraLsnr (ocf::heartbeat:oralsnr): Started db01 OraSrv (ocf::heartbeat:oracle): Started db01 Daemon Status: corosync: active/enabled pacemaker: active/enabled pcsd: active/enabled
ここで現在利用されている設定を保存するには、「crm configure save」を使います。
[root@db01 ~]# crm configure save /var/tmp/drbd.crm [root@db01 ~]# cat -n /var/tmp/drbd.crm 1 node 1: db01 \ 2 attributes standby=off 3 node 2: db02 \ 4 attributes 5 primitive FS Filesystem \ 6 params run_fsck=no device="/dev/drbd0" directory="/mnt/drbd" fstype=xfs \ 7 op monitor interval=15s timeout=40s \ 8 op start interval=0s timeout=60s \ 9 op stop interval=0s on-fail=ignore timeout=60s 10 primitive OraLsnr oralsnr \ 11 params sid=XE \ 12 op monitor interval=30s timeout=120s depth=0 \ 13 op start interval=0s timeout=120s \ 14 op stop interval=0s timeout=120s 15 primitive OraSrv oracle \ 16 params home="/u01/app/oracle/product/11.2.0/xe" sid=XE user=oracle \ 17 op monitor interval=120s timeout=60s \ 18 op start interval=0s timeout=120s \ 19 op stop interval=0s timeout=120s 20 primitive VIP IPaddr2 \ 21 params cidr_netmask=24 ip=192.168.1.221 nic=enp0s3 \ 22 op monitor interval=30s \ 23 op start interval=0s timeout=20s \ 24 op stop interval=0s timeout=20s 25 primitive prmPing ocf:pacemaker:ping \ 26 params attempts=5 debug=true host_list=192.168.1.1 multiplier=1 name=default_ping_set timeout=50s \ 27 op monitor interval=10s on-fail=restart timeout=60s \ 28 op start interval=0s on-fail=restart timeout=60s \ 29 op stop interval=0s on-fail=fence timeout=60s 30 primitive vipcheck VIPcheck \ 31 params count=3 target_ip=192.168.1.221 wait=5 \ 32 op monitor interval=10s on-fail=restart start-delay=0 timeout=60s \ 33 op start interval=0s on-fail=restart timeout=60s \ 34 op stop interval=0s on-fail=ignore timeout=60s 35 group Group-FS FS vipcheck VIP prmPing 36 colocation colocation-FS-OraLsnr-INFINITY inf: FS OraLsnr 37 colocation colocation-OraLsnr-OraSrv-INFINITY inf: OraLsnr OraSrv 38 order pcs_rsc_order_set_FS_OraLsnr _rsc_set_ FS OraLsnr 39 order pcs_rsc_order_set_OraLsnr_OraSrv _rsc_set_ OraLsnr OraSrv 40 property cib-bootstrap-options: \ 41 have-watchdog=false \ 42 dc-version=1.1.21-1.el7-f14e36f \ 43 cluster-infrastructure=corosync \ 44 stonith-enabled=false \ 45 no-quorum-policy=ignore \ 46 cluster-name=drbd_cluster \ 47 last-lrm-refresh=1560163421 48 rsc_defaults rsc_defaults-options: \ 49 resource-stickiness=INFINITY \ 50 migration-threshold=1
また、設定ファイルを読み込む場合は、「crm configure load」を使います。
[root@db01 ~]# crm configure load /var/tmp/drbd.crm
