DRBD 起搏器失敗

我是 Pacemaker 和 DRBD 的新手，但我必須將它們一起配置。我創建了 2 個 drbd 資源： Drbdwww 和 DrbdMysql 但是當我使用 drbd_mon 時出現以下錯誤：

Stack: corosync
Current DC: s-ha-web1 (version 1.1.15-e174ec8) - partition with quorum
Last updated: Mon May  8 21:58:45 2017          Last change: Mon May  8 21:58:36 2017 by hacluster via crmd on s-ha-web1

2 nodes and 7 resources configured

這是我的起搏器配置：

crm configure property stonith-enabled=false
crm configure property no-quorum-policy=ignore

crm configure primitive vip ocf:heartbeat:IPaddr2 params ip=192.168.100.100 cidr_netmask=24 nic="eth1" op monitor interval="30s" timeout="20s"

crm configure primitive Drbdwww ocf:linbit:drbd params drbd_resource="rwww" op monitor interval="30s" role="Slave" op monitor interval="29s" role="Master" 

crm configure primitive fsDrbdwww ocf:heartbeat:Filesystem params device="/dev/drbd0" directory="/var/www/html" fstype="ext4"

crm configure primitive DrbdMysql ocf:linbit:drbd params drbd_resource="rmysql" op monitor interval="30s" role="Slave" op monitor interval="29s" role="Master" 

crm configure primitive fsDrbdMysql ocf:heartbeat:Filesystem params device="/dev/drbd1" directory="/var/lib/mysql_drbd" fstype="ext4"

有人能幫我嗎 ？如果您需要更多資訊，請告訴我。

你在這裡錯過了很多。

首先，您需要為每個 DRBD 設備設置一個主從資源集。

然後，您可能想要創建資源組（fs、ip、服務），使用託管和排序約束來告訴這些組僅在其各自的 DRBD 設備被提升為主設備的位置/之後開始。資源組意味著組內資源的託管和排序。

Google 應該提供大量關於使用 DRBD 和 Pacemaker 設置 HA LAMP 堆棧的指南。

編輯：以答案的形式提供了更多資訊……我現在可以更具體了。

這就是您的 CIB（起搏器配置）應如下所示：

對 DRBD 資源的操作失敗可能意味著您沒有正確設置 DRBD 設備。您是否已經為設備創建了元數據？如果是這樣，您是否已經強制將一個節點提升到主節點以開始初始同步？的輸出是cat /proc/drbd什麼樣的？
