WOL - no working for groups.

[ablohowiak]

Ubuntu 14.04.4, fog 1.3 RC5
Individual systems will WOL, but not groups. There is no error in the apache log.

[Tom Elliott]

Wake On LAN will happen on all hosts in RC-6. This does also mean it will slow down group taskings a bit as it has to call SQL query for each host in the task.

[Wayne Workman]

Simple question but I have to ask it, make sure there are hosts in the group.

[ablohowiak]

@Wayne-Workman
I can appreciate starting simple. There are hosts in the group.

[Wayne Workman]

I moved this to fog problems for now.

When you do the WOL with groups, have a second tab open in your browser with the log viewer open. web interface -> fog configuration -> log viewer -> apache error logs

When you click the wol confirmation, watch the log viewer for a spamming of errors. If there are any, post those please.

[Tom Elliott]

WOL for groups is handled by the FOGScheduler service.

@Wayne-Workman
Just one line:

[:error] [pid 31478] [client :51206] PHP Strict Standards: Only variables should be passed by reference in /var/www/html/fog/lib/fog/fogpage.class.php on line 390, referer: http://fog/fog/management/index.php?node=group&sub=edit&id=1469

The results say the task was created, but nothing listed in active tasks.

[Tom Elliott]

@ablohowiak I’ll take a look at the active group tasks. I’m just guessing by “WOL -no working for groups” you’re meaning WOL Tasking specified from the Advanced Tasks menu item?

[ablohowiak]

@Tom-Elliott
Yes, but also as an imaging task, but I’ll need to re-confirm that piece. The service had crashed. I’ve confirmed the failure of WOL thru advanced task.

[Tom Elliott]

@ablohowiak I don’t understand.

When you create “imaging” tasks from the groups page, it’s not creating the actual tasks?

[ablohowiak]

@ablohowiak
No, that was as an advanced task.

[Tom Elliott]

@ablohowiak I still don’t understand.

When you group task an imaging type (Deploy, Deploy - Without Snapins, Deploy - Debug, Multicast) from groups does it create the tasks? The Advanced Tasks->Wake On Lan does not ever create task manager taskings.

Wake On LAN will happen on all hosts in RC-6. This does also mean it will slow down group taskings a bit as it has to call SQL query for each host in the task.

@Wayne-Workman Hi, working with @ablohowiak .

Here is what we got.
RC7
WOL to a group does NOT work.
WOL to individual host DOES work.
Groups to have members.
WOL does NOT work when deploying imaging task to group.

Apache Log

[Wed Aug 10 14:38:25.164390 2016] [:error] [pid 8234] [client 10.118.150.87:62661] PHP Warning: array_walk() expects parameter 1 to be array, null given in /var/www/html/fog/lib/fog/group.class.php on line 214, referer: http://fog/fog/management/index.php?node=group&sub=deploy&id=1504&type=14

[Tom Elliott]

@UWPVIOLATOR I need more information. The info, as I’m seeing, tends to show that hosts’ aren’t associated to that group. Why do I say that? The message you’re seeing will only show if there’s no hosts to work with.

From what I am seeing, this is exactly the case.

If you’d like you can try using the patch here:
https://github.com/FOGProject/fogproject/commit/23a856e8757a15b595c20c74ea9032427ef62084

See if it helps. Basically what it will do is attempt to grab the group’s hosts regardless of task type and tell all hosts to wake up if necessary.

@Tom-Elliott Thanks! this did the trick. WOL to groups is now working, but the apache log is spitting out this error now.
