Fog 1.1.0 multicast sits at "Starting to restore image (-) to device (/dev/sda1)

Tom Elliott

Thanks for reporting and I’ll fix it right now.

Toying around complete… Conclusions:
A) once base.inc.php is included, the full FOGCore/FOGBase is initialized. There doesn’t look to be any way I can see with the current structure to have the classes wait for the database when used as a daemon. Once called, an exception and exit is desired for normal circumstances (called via the CGI/Apache SAPI) if the database isn’t available. If we create an exemption for daemons (CLI SAPI) during DB class construction, then we are stuck with having to determine which service is currently executing and output to the correct output device the daemon for messages and waiting. I don’t see this as desirable operation inside the base DB classes as this isn’t the job of the DB class, or for that matter FOGCore/Base.

B) have a class specific to daemons that handles wait_interface_ready and wait_db_ready routines. Feasibly, the only use for these routines would be for the daemons anyways.

I’ve gone ahead and have done option B.

Attached are the patched /opt/fog/service/FOG*/FOG* files, as well as a Daemon.class.php (/var/www/fog/lib/fog/Daemon.class.php).
$Daemon->wait_db_ready() and $Daemon->wait_interface_ready() are both implemented. wait_interface_ready() has some fixes to make it a little more compatible with servers that are using Network-Manager/Network-Manager-Gnome.

Tested against Debian 7.6 and Ubuntu 14.04, with and without NM purged.

Hi

I have the same problem with fog 1.2 and ubuntu 10.04.
It stays at : Starting to restore image (-) to device (/dev/sda1) on my 8 computers
Any idea

Thanks

Mentaloid

1.2.0 stock has the known issue above… if you don’t wish to use the SVN tree, then the above scripts in my previous post could be applied manually.

I have the same setup as phm2000 and same issue. I tried the SVN tree following this instructions [url]http://www.fogproject.org/wiki/index.php/SVN[/url]

Unfortunattely the issue is still there.

Hi Mentaloid

I tried your files but same issue.
I tried svn, same issue.
The multicast task dissapear from list after 1 minute but individual tasks stays on active task list.

Have you tried making sure FOGMulticastManager service is actually running properly?

[code]sudo service FOGMulticastManager stop && sleep 30 && sudo service FOGMulticastManager start[/code]

Hi,

i made a complete fresh installation with Ubuntu Server 12.04.5 (and also Debian 7.5) and the lastest FOG SVN 2270 (yesterday) with in a NAT VM. I can´t do a multicast deploy of an image. I created a group and assigned one single client (NAT VM too) to this group. its not working (multicast deploy with a group to a single client also not working) . It´s starts up until it cames to the partclone screen. After this it hangs and nothing happens. With Unicast everything works fine and i can create and deploy an image.

In the LOG-Viewer i found serveral entrys about

[CODE][09-10-14 7:18:25 am] | Task (1) mcgroup-with-one-client is already running PID 3999
[09-10-14 7:18:35 am] | Task (1) mcgroup-with-one-client is already running PID 3999
[09-10-14 7:18:45 am] | Task (1) mcgroup-with-one-client is already [/CODE]

I´m also noticed that the time is incorrect. I tried to correct it with the hints i found in the forum but it shows still the wrong time. I´am also tried to apply the patches i found here in the thread but it looks like they are already there.

With the new SVN i found the Option Multicast-Image under “Image-Management”. When i create with this an multicast session, start the clients over pxe and select “Join Multicast Session” the multicast restore working. This is really confusing that it is working this way but not the way through the group management.

Here the install Log:

I hope you can help me

I’m aware of a problem with multicast starting and the only work around I have found is to truncate your multicastSessions and multicastSessionsAssoc tables. On the fog server, kill all the current udp-sender processes.

[code]mysql -u root [ -p’PASSWORDHERE’ #only if you have a mysql password] fog
truncate table multicastSessions;
truncate table multicastSessionsAssoc;
delete * from tasks WHERE taskTypeID=‘8’;
exit;
sudo killall udp-sender; sudo killall udp-sender; sudo killall udp-sender
sudo service FOGMulticastManager restart;[/code]

Then recreate your multicast task (not the one to “join” session). All should work.

kimbo

No sorry i had no luck. multicast still not working. unicast for create/deploy an image are working. he still hangs at the same point at the partclone screen. I also tried debug mode - everything looks fine, no errors on screen until this point.

MarcoN

Has there been any news on this on development point of view?

Hi

I tried it but without success, it stays blocked at “starting to restore image”

Bobfrid

Not sure this is related to any of the previous issues in the thread, but I had several Ubuntu 14.04 Fog servers using 1.2.0 that would unicast perfectly but get “starting to restore image” when multicasting.

I finally found that the FOG_UDPCAST_INTERFACE value under Multicast Settings was wrong. It was set to eth0 while my adapter was eth1. Not sure how I managed that, but hope it helps someone.

MarcoN

Thanks for the suggestion Bobfrid, but unfortunattely i had my FOG_UDPCAST_INTERFACE set to eth0 ,and this is the correct interface.

TaTa

This works for me on svn 2765 as suggested by Tom but this is not permanent. Multicast always breaks when the server restarted and clients stuck at “Starting to restore image screen…” Does anyone know how to make it permanent? Thank you.

Chris Shanks

Hey Guys, Just wondering if people are still having this problem with newer versions of svn (2923). Tom is this something you have time to look at amongst everything else you do?

Thanks

Tom Elliott

I’m aware that people are still having issues.

As such,

If you add the necessary components to the rc.local file for your particular OS, things should work as expected.

The first steps seem to me that you would need to disable services to don’t start properly at boot time.

These services, in my knowledge, consists of:

tftpd-hpa (ubuntu), mysql (ubuntu), FOGMulticastManager, FOGSnapinReplicator, FOGImageReplicator, and FOGScheduler.

I’d also like to state that this issue only appears (from the capabilities I’ve found) to happen with OS’s that deal with startup scripts through the use of systemd (e.g. systemctl) and does not seem to affect sysvinit as programs are started on a priority list rather than dependent upon the startup of devices/networking while the main program starts first.

The step’s I’d take to do this:

For Ubuntu/Debian based on systemd run
[code]sudo update-rc.d mysql remove
sudo update-rc.d tftpd-hpa remove
sudo update-rc.d FOGMulticastManager remove
sudo update-rc.d FOGImageReplicator remove
sudo update-rc.d FOGScheduler remove

only if on current version of SVN that contains snapinreplicator

sudo update-rc.d FOGSnapinReplicator remove

#Run these just to ensure things are truly off
sudo sysv-rc-conf tftpd-hpa off
sudo sysv-rc-conf mysql off
sudo sysv-rc-conf FOGMulticastManager off
sudo sysv-rc-conf FOGImageReplicator off
sudo sysv-rc-conf FOGScheduler off

Only if on current version of SVN that contains SnapinReplicator

sudo sysv-rc-conf FOGSnapinReplicator off
[/code]

Then edit the /etc/rc.local so it looks like:
[code]#!/bin/bash
sleep 30
systemctl start tftpd-hpa
systemctl start mysql
systemctl start FOGMulticastManager
systemctl start FOGScheduler
systemctl start FOGSnapinReplicator
systemctl start FOGImageReplicator
exit 0[/code]

Then edit the /etc/rc.local (on ubuntu) or /etc/rc.d/rc.local (Fedora/Maybe Centos/Redhat 7?)
Add the lines (before exit 0). If the file is being created you’ll need to add the exit 0 as the last line.

For Fedora/CentOS/Redhat
[code]systemctl disable FOG{MulticastManager,Scheduler,SnapinReplicator,ImageReplicator}[/code]
Edit /etc/rc.d/rc.local (unless /etc/rc.local exists in which case us /etc/rc.local)
If /etc/rc.local does not exist, first run:
[code]touch /etc/rc.d/rc.local;chmod +x /etc/rc.d/rc.local[/code]
Then edit the file and make it look like:
[code]#!/bin/bash
sleep 30
systemctl start FOGMulticastManager
systemctl start FOGScheduler
systemctl start FOGSnapinReplicator
systemctl start FOGImageReplicator
exit 0[/code]

I tried this and get an error when running the delete commands after successfully running the truncate commands. "error 1064 (42000): you have an error in your sql syntax…check … for the right syntax to use near ‘* from tasks WHERE taskTypeID=‘8’’

I was just copying from the post so not sure if there was a typo.

Thanks,
Caleb

Sebastian Roth

Syntax should be:
[CODE]delete from tasks WHERE taskTypeID=‘8’;[/CODE]

Be aware that this sql statement deletes stuff from your database and you won’t be able to get those entries back easily! I am not saying that you should not delete. Just want to make sure you know what you do!
