I am not an expert in drbd, but with the configuration that I have
according to the documentation, should not this situation happen, or
am I wrong?

[DRBD-user] secundary not finish synchronizing

[Ricky Gutierrez]

Hi list , I have a problem, I have two mail servers that replicate a
secondary disk between them, there I have the mailboxes, they are as
primary and secondary with centos 7, the problem is that there was a
power cut twice, the primary server finished synchronizing with the
secundary , and then there was another power cut and the secondary
shutdown too, after this the power was restored and both power  on.

The problem is that I have lost data yesterday and today 

version of drbd

drbd84-utils-sysvinit-9.1.0-1.el7.elrepo.x86_64
kmod-drbd84-8.4.10-1_2.el7_4.elrepo.x86_64
drbd84-utils-9.1.0-1.el7.elrepo.x86_64
