DRBD起搏器失败

Question

我是新来的心脏起搏器和DRBD的，但我必须把它们配置在一起。我创建了两个drbd资源: Drbdwww和DrbdMysql，但是当我使用drbd_mon时，我有以下错误：

Stack: corosync
Current DC: s-ha-web1 (version 1.1.15-e174ec8) - partition with quorum

这是我的起搏器配置：

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"

有人能帮我吗？如果你需要更多的信息，请告诉我。

Answer 1

你在这里错过了很多。

首先，您需要为每个DRBD设备设置一个主从资源集。

然后，您可能想要创建一组资源(fs、ip、service)，使用协同定位和排序约束告诉这些组只在它们各自的DRBD设备被提升为master之后才开始。资源组意味着资源在组内的位置和顺序。

Google应该提供许多指南，说明如何使用DRBD和Pac怪人来设置HA灯栈。

编辑:更多信息是以答复的形式提供的.我现在可以说得更具体了。

您的CIB (起搏器配置)应该是这样的：

node 1: s-ha-web1
node 2: s-ha-web2
primitive Drbdwww ocf:linbit:drbd \
    params drbd_resource="rwww" \
    op monitor interval="30s" role="Slave" \
    op monitor interval="29s" role="Master"
primitive DrbdMysql ocf:linbit:drbd \
    params drbd_resource="rmysql" \
    op monitor interval="30s" role="Slave" \
    op monitor interval="29s" role="Master"
primitive fsDrbdwww ocf:heartbeat:Filesystem \
    params device="/dev/drbd0" directory="/var/www/html" fstype="ext4" \
    op monitor interval=30s timeout=30s
primitive fsDrbdMysql ocf:heartbeat:Filesystem \
    params device="/dev/drbd1" directory="/var/lib/mysql_drbd" fstype="ext4" \
    op monitor interval=30s timeout=30s
primitive vipwww ocf:heartbeat:IPaddr2 \
    params ip=192.168.100.100 cidr_netmask=24 nic="eth1" \
    op monitor interval="30s" timeout="20s"
primitive vipmysql ocf:heartbeat:IPaddr2 \
    params ip=192.168.100.101 cidr_netmask=24 nic="eth1" \
    op monitor interval="30s" timeout="20s"
primitive httpd ocf:heartbeat:apache \
    op start interval=0s timeout=40s
    op stop interval=0s timeout=60s
    op monitor interval=20s timeout=20s
primitive mysql ocf:heartbeat:mysql \
    op start interval=0s timeout=120s
    op stop interval=0s timeout=120s
    op monitor interval=20s timeout=30s

    meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true

    meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true
property cib-bootstrap-options: \
    stonith-enabled=false \
    no-quorum-policy=ignore

DRBD资源上的失败操作可能意味着您没有正确设置DRBD设备。您是否已经为设备创建了元数据？如果是这样的话，您是否已经强制将一个节点提升到主节点以启动初始同步？cat /proc/drbd的输出是什么样子的？

Answer 2

谢谢你的回答。我与vip Drbdwww DrbdMysql fsDrbdwww fsDrbdMysql apache2 mysql一起创建了一个名为haweb的组，但是当我想创建主从资源时，出现了一个错误，因为Drbdwww和DrbdMysql是haweb组的子代。我删除了haweb组并使用

ms ms_drbdMysql DrbdMysql \
        meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true
ms ms_drbdwww Drbdwww \
        meta master-max=1 master-node-max=1 clone-max=2 clone-node-max=1 notify=true

但我还是失败了(阻止)：

 Master/Slave Set: ms_drbdwww [Drbdwww]
     Drbdwww    (ocf::linbit:drbd):     FAILED s-ha-web2 (blocked)
 Master/Slave Set: ms_drbdMysql [DrbdMysql]
     DrbdMysql  (ocf::linbit:drbd):     FAILED s-ha-web2 (blocked)
* fsDrbdwww_start_0 on s-ha-web1 'unknown error' (1): call=14, status=complete, exitreason='Couldn't mount filesystem /dev/drbd0 on /var/www/html',
    last-rc-change='Mon May  8 23:24:04 2017', queued=0ms, exec=17ms
* fsDrbdMysql_start_0 on s-ha-web1 'unknown error' (1): call=21, status=complete, exitreason='Couldn't mount filesystem /dev/drbd1 on /var/lib/mysql_drbd',
    last-rc-change='Mon May  8 23:24:04 2017', queued=0ms, exec=17ms

现在，我在服务器1上有一些资源，在服务器2上有一些其他的资源:(我将搜索更多关于协同定位和组的信息！谢谢

编辑:我不知道如何创建我的团队(S)和定位(S)，我是否必须创建两个VIP ?一个为apache +DRBD，一个为mysql和DRBD？
