腦裂恢復文件系統未安裝後

我有一個帶起搏器+裂腦的主動/被動高可用性集群。在腦裂狀態後，我使用自動腦裂恢復來恢復我的系統。

問題在於，由於文件系統資源由 CRM 管理，因此在腦裂恢復後沒有安裝它。裂腦恢復後什麼都沒有安裝！

看來我應該使用stonith設備，但我的老闆要求我在沒有任何額外設備的情況下解決它！如何將腦裂情況通知給起搏器，以便它重新掛載文件系統資源？

編輯：我的 crm 配置

node drbd3
node drbd4
primitive apache ocf:heartbeat:apache \
       params configfile="/etc/apache2/apache2.conf" httpd="/usr/sbin/apache2" \

       expected-quorum-votes="2" \
       stonith-enabled="false" \
       no-quorum-policy="ignore"

和我的 drdb 配置：

global { usage-count no; }
common { syncer { rate 100M; } }
resource r0 {
       protocol C;
       startup {
               wfc-timeout  1;
               degr-wfc-timeout 1;
       }
#       disk{
#               fencing resource-only;
#       }
       handlers {
               #split-brain "/usr/lib/drbd/notify-split-brain.sh root";
#                fence-peer "/usr/lib/drbd/crm-fence-peer.sh";
#                after-resync-target "/usr/lib/drbd/crm-unfence-peer.sh";

       }

       net {
               cram-hmac-alg sha1;
               shared-secret "test";
              # allow-two-primaries;
               after-sb-0pri discard-zero-changes;
               after-sb-1pri discard-secondary;
               after-sb-2pri call-pri-lost-after-sb;
       }
       on drbd3 {
               device /dev/drbd0;
               disk /dev/sda1;
               address 10.8.0.93:7788;
               meta-disk internal;
       }
       on drbd4 {
               device /dev/drbd0;
               disk /dev/sda1;
               address 10.8.0.94:7788;
               meta-disk internal;
       }
}
#include "drbd.d/global_common.conf";
#include "drbd.d/*.res";
~                          

對於上述情況，您可以添加以下行來/etc/rc.local解決問題 -

#drbdadm secondary resource-name<resource> 
#drbdadm disconnect resource-name<resource>
#drbdadm -- --discard-my-data connect resource-name<resource>

將上述命令添加到 NODE-1

$$ primary/Active node $$ /etc/rc.local文件

drbdadm connect resource-name<resource>

將上述命令添加到 NODE-2

$$ Secondary/Passive node $$ /etc/rc.local文件
