HA Operation Would Break Failover Plan

olivierlambert

So you have HA enabled on the pool, right? How did you enabled in the first place? (the command used)

Midget

xe pool-ha-enable heartbeat-sr-uuids=<XOSTOR UUID>

I ran this on the pool master.

olivierlambert

Can you do a xe pool-ha-compute-max-host-failures-to-tolerate please?

Midget

@olivierlambert 3 good Sir.

olivierlambert

Hmm that's probably the issue

Can you do xe pool-param-set ha-host-failures-to-tolerate=2 uuid=pool-uuid and then retry to enable HA on your VM?

Midget

It's been a long week. I have wasted your time. I never installed the guest tools.../facepalm

EDIT
I realized it right after I ran that command. HA is now enabled.

olivierlambert

So the error message was not great. It worked a soon you got tools installed in the VM?

Midget

@olivierlambert Correct Sir. I apologize for wasting your time.

olivierlambert

Don't worry. The error message was not great. Time to enjoy the week-end

Hi,
I'm getting same error - HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN() - when I try to put host in maintenance mode.
I have 3 nodes in pool and I set xe pool-ha-compute-max-host-failures-to-tolerate to 1.
In error log I'm not able to find why causes this error.
Any ideas? Tools are installed on all VMs.

@arc1 What does xe pool-ha-compute-max-host-failures-to-tolerate return?

@Danp said in HA Operation Would Break Failover Plan:

xe pool-ha-compute-max-host-failures-to-tolerate

It returns 1.:
[13:34 log]# xe pool-ha-compute-max-host-failures-to-tolerate
1
