Failover timer question

Hi!

Currently trying to tune OracleVM 3.2.8 + OEL6.5 64 bit as VM to survive storage failover.

I have tuned Oracle VM heatbeat parameter the following way:

in /etc/sysconfig/o2cb set to "O2CB_HEARTBEAT_THRESHOLD = 301" and ovs servers restarted

Then 4 Repositories were added to 2 OVS servers via SAN LUNs. In each repository 1 VM was started.

Plan was to run same script in each VM that just copies data from one file to other to make write load on LUNs.

script:

----

#!/bin/bash

while [ true ]

do

echo "writing samplefile" ; dd if=/root/samplefile | pv | dd of=sample-copy

done

----

Initially script was started in just 1 VM.
