解決:

fdisk /dev/sdb 刪除該分區保存，然后再重新新建分區并保存即可

問題6:

提示unknown resource

#?drbdadm?primary?r1 r1:?Failure:?(158)?Unknown?resource additional?info?from?kernel: unknown?resource Command?'drbdsetup?primary?r1'?terminated?with?exit?code?10

解決:

#?/etc/init.d/drbd?start

問題7及解決:

#?drbd-overview?1:r1/1??Connec/Connec?Second/Unknow?UpToDa/DUnkno#?systemctl?stop?firewalld#?drbd-overview?1:r1/1??Connec/StaAlo?Second/Unknow?Outdat/DUnkno#?getenforce?0

?

問題8:

node2無法連接node1,顯示node1為StandAlone

node1:

[root@node1?~]#?drbd-overview?1:mysqldata/1??Connec/Connec?Second/Unknow?UpToDa/DUnkno

node2:

[root@node2?~]#?drbd-overview?1:mysqldata/1??Connec/StaAlo?Second/Unknow?UpToDa/DUnkno

解決:

[root@node2?~]#?drbdadm?--discard-my-data?connect?all [root@node2?~]#?drbd-overview?1:mysqldata/1??Connec/Connec?Second/Unknow?UpToDa/DUnkno? [root@node2?~]#?drbd-overview????????????????????##從上一狀態轉為該狀態需要些時間1:mysqldata/1??Connected(2*)?Secondary(2*)?UpToDa/UpToDa

問題9及解決:

node1和node2互相認為對方StandAlone

node1:

[root@node1?~]#?drbd-overview?1:mysqldata/1??Connec/StaAlo?Second/Unknow?UpToDa/DUnkno? [root@node1?~]#?drbdadm?--discard-my-data?connect?all [root@node1?~]#?drbd-overview?1:mysqldata/1??Connec/Connec?Second/Unknow?UpToDa/DUnkno

node2:
