S12: detecting from the state of node DRBD virtual disk, if normal, that is, when display UpToDate character, represent from
The DRBD virtual disk of node is in synchronous normal condition with host node, then enters distal end role and check, because using
When Keepalived is serviced, host node can be sent to always from node VRRP broadcast packet, tell that it also lives from node, distal end angle
Color inspection namely monitor whether can receive host node transmission broadcast packet, when from node listen to host node send it is wide
When broadcasting packet, illustrate that host node also lives, does not need to switch the identity from node；It is wide less than what host node was sent when being monitored from node
When broadcasting packet, just will start related service adapter tube resource, virtual ip address drift to it is a certain from node, and by the identity from node
It is changed into host node, Mount mount point carry file system then is carried out to new host node again, and carry out carry dotted state
It is detected with virtual IP address state, when carry dotted state and normal virtual IP address state, terminates this heartbeat detection, when main section
When point breaks down, the continuity and high degree of availability of business ensure that from the conversion of the identity of node.

Sampling of data step: each Backup Data stored from node of sampling；
Verification of data step: the data that each Backup Data sampled from node is stored with host node one by one are subjected to core
It is right, and to each from vertex ticks checked result；For example, checked result can take the mode of hundred-mark system to show, according to backup number
Percentage is determined according to the similarity degree of the data stored with host node, it is assumed that Backup Data and the data that host node stores are complete
It is overlapped, then checked result is absolutely, it is assumed that Backup Data can be overlapped with the data only half that host node stores, then checked
It as a result is 50 percent；
Node screening step: it is filtered out according to checked result standard compliant from node；For example, checked result is percent
90 or more comply with standard；
Performance judgment step: judge the standard compliant performance from node, and carried out according to the superiority and inferiority of performance to from node
Priority ranking；Performance can be judged from many aspects, for example, the memory capacity of storage server, processor processing speed,
Handling capacity etc.；
Virtual IP address drifts about step: virtual IP address drifting to the slave node of highest priority, and save based on switching from node
Point.
It is destroyed because being possible to from the Backup Data of node, when host node is without failure, will be incited somebody to action
The data that each Backup Data sampled from node is stored with host node one by one are checked, first is that in order to detect from node standby
