Nexus3 shared storage startup failed

  I want to keep the artifacts of the validation environment and the Disaster recovery environment synchronized。monitor the environment nexus sonatype-work files through inotify, and use Rsync for data synchronization。
  Here are my problems。

1、The Disaster recovery environment nexus cannot be started。When I close the verification environment neuxs, the Disaster recovery environment starts successfully。(Only one process can exist at a time)
2、Due to the above problems, I use crontab to set the scheduled restart of Nexus (. / nexus restart). Sometimes the process exists and 8081 cannot be accessed。(Share sonatype-work data)
Who can tell me what caused it。thank~
