Power on function
-
@olivierlambert It did now but never did before
I wonder if it is because the same host the command was run against was the master at the time and is now. Perhaps server 2 as master previously failed when the command was on server 1.
Makes no sense to me. All good for now. Thank you.

@olivierlambert Nope, I didn't wait long enough. It's back.

It's not the same task (new UUID)
-
@olivierlambert correct, which tells me it has been added again by something else. XO? Where I initated the command originally?
-
You can check who did this in the
audit.logfile of your master

This is for task destroy, not a task creation.
-
@olivierlambert it is all I see from:
fgrep Async.host.power_on /var/log/audit.log
-
Grep on
host.power_onto see if it's better. -
fgrep host.power_on audit.log.1 | fgrep -v destroy | fgrep -v cancel

-
It's possible that XAPI recorder the
host.power_onand loop on trying to do that, but to be fair, I never saw that before
Can you power on that host to see if it stops?
-
Going back as far as I can to audit.log.7.gz only takes me back to June 30 and this has been a problem for more than a month so I don't think I can find the original request.

I had the whole rack powered off yesterday, 2 - XCP-NG 8.1 servers (DL380 Gen9), 1 Freenas (DL380 Gen9) for iSCSI VDIs. It still came back.
-
So now everything is back online but despite that you got the task?

Yes, everything is up and working, just the task appears in XO and also on the master's tasks list as we see.
-
Weird. Can you disconnect XO from this pool, restart toolstack on master, and see if the task is popping again? I think it will, I don't see why XO would do that.

I would remove the hosts from XO, restart toolstack, add hosts back to XO? Is this correct?
-
Don't add host back in XO for few minutes, and check if
xe task-listgot the task appearing without any XO connection. -
Host #2 has been powered off during these checks. I will power it on so that all pool members are available and try xe task-cancel again. Then proceed with your suggestion. Standby.
-
OK this is interesting (host1 is master). I powered on host2 and ... the task disappeared from xe task-list and XO Tasks.
I powered off host2 again and the task is back.
