主题: about vms can't migrate automatically in HA

 

hello,my enviroment :
host A : engine ,
host B : compute,host of cluster
host C : compute,host of cluster
And run a vm in host B,mount nfs on host B
i use A to provide nfs storage to host B and C as shared storage.i just want to realize HA without any mannul operation.

the problem is:
1,i just satified the condition of HA ,like configure power manager,vm HA parameters...and keep default else.
if i just maintenance host B,it works well to migrate vm,okay.

And then i power down by power manager,it seems that vm can run on host C until host B reboot by power manager,but it also works,it is weird ,through host B is down,i expect host C will mount nfs automatically ...

2, i force to power failure host B,the result is: 

host B and C both turn to Non Responsive,and the storage is down,everything is bad ..are there some place i ignore?

it make me feel helpless.
best regard.
