Hi All,
I join to this message an extract of the engine.log.
To complete informations, the node which I turn off is a R620 with a drac7
fence agent.
When poweroff, after few seconds (perhaps 1 minute), this server is turn
on automatically (drac command I think).
Adding Roy to the discussion. @Roy, any ideas?
This VM is Windows 10 but I also have test with linux VM and the
result
is the same.
Another question not related to this subject is that all my windows VM are
with an orange exclamation point. I don't see anywhere any reason !
Thank's,
SJ

Hi everybody,
After testing some features on 3.5, we are planning to finaly go to 3.6.
Some problems still exist.
A major problem still remain on the « Highly Available » option on vm wich
doesn't work. I had a cluster with 4 engines and a simple vm. When I start
a poweroff from the node where this vm is living, the node is shutting down
but my vm doesn't restart on another node of the cluster.
Do you have a fencing agent configured for your host? It is configureable
under 'Edit Host'->'Power Management'. If there is no fencing agent
configured, the engine can not make sure that the host is really off when
it is non responsive. To avoid disk corruptions without a fencing agent, it
does nothing. You can find more about HA here [1]. About fencing here [2].
The power managment of all the node are correctly configure.
Oh I missed that. When that is configured correctly, as @Simone already
said, the logs would be great.
The HA feature of then hosted-engine is working well (except it is very
long).
Glad to hear that this is working. Regarding the (sometimes long)
downtimes, you can find some numbers here [3].
Another problem consist of passing usb host device to the virtual machine.
We've got some specials usb keys for activating old application and we need
to attach this key to vm. At first, I try with standard usb mass storage
key to test this approach. I can't start virtual machine when I add usb
device, I always have the message « The host . did not satisfy internal
filter HostDevice because it does not support host device passthrough ».
Have any idea where I can find an HowTo to help me ?
Tanks for your help,
SJ
