The switching of disk is not completed in heartbeat threshold range, each node can not still update the time of oneself in system
Stamp, then system trigger enters the operation of service mode, i.e., virtual machine relevant with the domain enters halted state by system itself,
To protect data integrity.Shared storage also enters service stopping involved in maintenance state, domain, and passes through system bullet frame and postal
The modes such as part inform that user is abnormal, and please handle in time.This process is system itself detection function, is not needed artificially dry
In advance, guarantee to can be handled in time the problem.
For example, running in virtual machine, business is more important, then the heartbeat threshold value setting time is shorter, such as 30s, it is ensured that
The probability that virtual machine loses data lowers, but the fault-tolerance of simultaneity factor can reduce, i.e. the time of permission heartbeat disconnection is longer, holds
Mistake is higher.When there is heartbeat disk exception, i.e. IO error or disk loss, can system default heartbeat threshold value be 30s.
Within the scope of 30s, virtualization system detects whether the backup heartbeat disk of heartbeat disk.If it exists, backup magnetic is detected first
The IO characteristic of disk obtains the scsi id of backup heartbeat disk, and is directed toward by database update heartbeat disk when IO is met the requirements
Disk scsi id, make heartbeat disk be directed toward backup heartbeat disk.
If system does not back up heartbeat disk in handoff procedure, the IO characteristic of backup heartbeat disk is unsatisfactory for requiring and surpass
Heartbeat threshold time 30s is crossed, then system trigger domain enters service mode, suspends operation, and guarantees data integrity.
