The present invention discloses a method for realizing disaster recovery switching of storage without interrupting the Linux system service, and belongs to the field of computer storage. The method for realizing disaster recovery switching of storage without interrupting the Linux system service disclosed by the present invention uses storage disaster recovery, failover and Linux system technologies. The Failover function is implemented by an underlying RVM and an upper layer pacemaker; the RVM implements the master and backup data mirroring and synchronization; and the pacemaker implements resource switching and ensures that the data is not lost. According to the method for realizing disaster recovery switching of storage without interrupting the Linux system service disclosed by the present invention, when carrying out disaster recovery switching, there is no need to restart the machine and to interrupt the service, on the premise of ensuring stability, rapid storage of data is ensured, and the good promotion and application value is realized.
