Power on function

dsiminiuk

Restarting the toolstack from XO or XCP-ng didn't clear it.

I'm manually powering up host 2 to migrate all VMs and change the pool master so I can reboot host1.

dsiminiuk

The unresolved task disappeared once host2 became available.

dsiminiuk

Now that host1 is powered off.

Parameters seem ok.

power-on-mode ( RO): iLO
power-on-config (MRO): power_on_ip: 192.168.1.44; power_on_user: Administrator; power_on_password_secret: 94171423-9ac2-beac-6b87-81699a0a7de6

Run...

xe host-power-on host=cdb42b94-7ec6-47b4-aaef-d4c52f6bd7b3

The cursor sits at column 1 after the newline from the command and never times out.

I know this isn't an XO problem, but in case somebody else gets this far...

I'm going to have to get into tcpdump to find out what is going on there.

olivierlambert

Are you trying to power on the master? If yes, it won't work, only the master can boot slaves.

dsiminiuk

@olivierlambert No, I'm on the master trying to power on the slave.

dsiminiuk

Async.host.power_on  (on xcpnghost1) 0%

Persists in the web UI Tasks panel no matter what I do.
Restarted toolstack,
Shut down the entire environment and restarted.
No way to cancel it or delete it.

olivierlambert

Are you sure it's not a XO refresh issue?

dsiminiuk

@olivierlambert It's been there since I played with power on function that failed.

Where is this task event stored? On the master? On XO?

How can I query it from a command line?

olivierlambert

xe task-list on any pool member

dsiminiuk

@olivierlambert said in Power on function:

xe task-list

Oh, that was too easy. There it is.

uuid ( RO)                : e1896255-fbec-76d6-c2f4-9c2829c1f72b
          name-label ( RO): Async.host.power_on
    name-description ( RO):
              status ( RO): pending
            progress ( RO): 0.000

xe task-cancel uuid=e1896255-fbec-76d6-c2f4-9c2829c1f72b

Doesn't cancel it.

olivierlambert

Okay and a toolstack restart on the master doesn't clean it?

dsiminiuk

@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.

dsiminiuk

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

uuid ( RO)                : 4d1971f4-4895-78c8-2856-d679d457b75e
          name-label ( RO): Async.host.power_on
    name-description ( RO):
              status ( RO): pending
            progress ( RO): 0.000

olivierlambert

It's not the same task (new UUID)

dsiminiuk

@olivierlambert correct, which tells me it has been added again by something else. XO? Where I initated the command originally?

olivierlambert

You can check who did this in the audit.log file of your master

olivierlambert

This is for task destroy, not a task creation.

dsiminiuk

@olivierlambert it is all I see from:

fgrep Async.host.power_on /var/log/audit.log

olivierlambert

Grep on host.power_on to see if it's better.
