Host downtime before automatic failover < 5 Minutes not posible

Submitted by gnilebein on Thu, 10/06/2011 - 06:57

The status.pl cronjob runs every 5 minutes by default.

If you configure a Host downtime before automatic failover smaller then 5 minutes, it will never work.

Please add a feature to adjust the cronjob depending on the configured wait time or create a cronjob for the failover.

It can lead to further problems:

The wait time is 5 Minutes:

13:52: Xen host goes down 13:55: Run Cronjob, but the 5 minute wait time is not over. The failover won't start 13:57: Wait time is over... But no cronjob at this time 14:02: Cronjob will start the failover.

In this time you have to wait 10 Minutes befor the automatic failover is done...

Yes, that is sort-of expected .. the 5 minute timer starts when Cloudmin first detects the VM is down, which can only happens on 5-minutely run of status.pl.

One work-around is to adjust the /etc/webmin/server-manager/status.pl job to run every minute, at Webmin -> System -> Scheduled Cron Jobs. This will increase the load on your master system due to more frequent status checks though..
