[quote=“Jose Antonio Sanchez, post: 35969, member: 25349”]I could not get Ubuntu to PXE boot with network access, it doesn’t see any network cards… Ubuntu Live takes a while to boot on a 100MB network too…

The ethtools… I’ll give it a try…

DebugMode does show the Link Speed as it boots:

e1000e: eth0 NIC Link is Up 100Mbps Full Duplex, Flow Control: None

I learned that you can Shift + PgUp to scroll back into the boot time messages…[/quote]

Yeah ran into the same problem, here’s my solution on Ubuntu:
sudo dhclient eth0

[quote=“Jose Antonio Sanchez, post: 35934, member: 25349”]Is there a way to display Link Speed? 10Mbit 100Mbit 1000Mbit??
Or is there a very light boot disk that can do it???

I looked over at the ipxe.org site and could not find anything on link/media speed…

Any ideas???

Having this info helps reduce the time figuring out which PC is the bad one when there is very slow multicast…[/quote]

I usually live boot ubuntu then test from speedtest.net.

Also can break the group into smaller groups, then test multicast speed, determine which group is slower, repeat until you only have a few computers to test.

I had to troubleshoot a lab of 60 computers and that’s how I did it. Not super elegant unfortunately.

It might also be possible to boot into debug mode and run a few linux commands like ethtools to see link speeds.

[quote=“Jose Antonio Sanchez, post: 35737, member: 25349”]/images as in the same as where the computer images get stored and therefore that’s where my /ubuntu folder should be at
[/quote]
That one.

/var… is boot_url and web directory
/images is where the rest of your images are stored. that should have a fully extracted ubuntu dvd in a directory there. i

set boot_url [url]http://${fog-ip}/fog/service/ipxe[/url]
set boot_nfs 128.104.71.88:/images

So I no longer think Multicast not working on CentOS 7 is related to a database issue. Tested by importing a functional Centos 6.5 Fog 1.2 database to the CentOS 7 install of fog and updating the users privileges. Anybody got any ideas?

[quote=“Jose Antonio Sanchez, post: 35731, member: 25349”]madskillz23,

Did you get Ubuntu 14.04 to boot??

I extracted all the files from the ISO and put them into /images/ubuntu14041/ and it tries to boot but I get the “(initramfs) Unable to find a live file system on the network” message…[/quote]

I am pretty sure these work. Let me know if they don’t though and I should be able to find the backup copy of the arguments.
[CODE]:Xubuntu14
kernel ${boot_url}/xubuntu14.04/casper/vmlinuz.efi root=/dev/nfs/ boot=casper netboot=nfs nfsroot=${boot_nfs}/xubuntu14.04/
initrd ${boot_url}/xubuntu14.04/casper/initrd.lz
boot

initrd ${boot_url}/ubuntu14.04/initrd.lz
#imgargs
boot[/CODE]

Here are the lines neccesarry to make NFS work in the install script. Could use the same selector template for rhel 7 versions as the code above in NFS, but it might be better to generalize something.
[CODE] systemctl restart nfs-server.service >/dev/null 2>&1;
systemctl restart rpcbind >/dev/null 2>&1;
systemctl enable rpcbind >/dev/null 2>&1;
systemctl enable nfs-server.service 2>&1;[/CODE]

Here’s the code to fix the installer for MySQL in all redhat based distros. I tested it on my own system and it should work.
Still stuck on getting multicast working.
[CODE]ConfigureMySql()
{
echo -n " * Setting up and starting MySQL…";
RHVER=rpm -qa|grep release|xargs rpm -q --queryformat '%{VERSION}'|cut -c -1;
if [ “$RHVER” == “7” ];
then
systemctl enable mariadb.service >/dev/null 2>&1;
systemctl restart mariadb.service >/dev/null 2>&1;
else
chkconfig mysqld on;
service mysqld restart >/dev/null 2>&1;
service mysqld status >/dev/null 2>&1;
fi
if [ “$?” != “0” ];
then
echo “Failed!”;
exit 1;
else
echo “OK”;
fi
}[/CODE]

Its probably a problem with your DHCP config. The boot filename should not be pxelinux.0, it should be undionly.kpxe. I just setup another fog server using CentOS 6.5 today and there are no quirks with that distro.

For all images run:

[CODE]mkdir /images/IMAGE_NAME

mv /images/dev/IMAGE_YOU_JUST_UPLOADED/* /images/IMAGE_NAME

chmod 777 /images/IMAGE_NAME[/CODE]

This is a bandaid that will allow you to image right now, it doesn’t fix the root of the problem.

Hi Tom, thank you for the response. The issue I have is that while my site has many FOG servers, they are now all independent and on separate subnets protected by firewalls. All of my CentOS 7 nodes I am testing are the ONLY fog servers on those subnets. They all are completely independent of one another, each one being responsible for PXE, httpd, imaging, and WOL etc. They are all master/enabled, and unicast works just fine from those servers. Also, doing manual multicast by manually sending the udp-cast command and a client debug task, I am able to multicast just fine.

I just took down the CentOS 7 server on one of the lab vlans, replaced it with a CentOS 6 FOG server, and now multicast works. The multicast log reports “*No Tasks found” by default. I seriously doubt any parts of the configuration in FOG have changed besides the OS’s in this new setup. I believe that $StorageNode should be returning the info of the current machine, and on CentOS 7 it is not, even though that server is master, enabled, and stores images.

I now believe this is a database issue, as on CentOS 7, the database/schema updater is never promted for on the web interface during the install process, because the installer script doesn’t properly handle systemd init scripts for mySQL. I will work on fixing and testing that part this afternoon, and see if that helps things.

Is it the same exact physical machine in both images? Manufactures sometimes switch out hdd’s among the same models of machines and that will result in different speeds.

Otherwise if you uploaded from both fog and clonezilla, FOG uses more compression than Clonezilla which results in a slower download speed, but less disk space taken up on your server.

Any developers have an idea why the $StorageNode in the following command isn’t valid here? Php is not my forte. I believe this is the first step into finding out why multicast doesn’t work on CentOS 7.
This is in 1.2.0/packages/web/lib/fog/MulticastManager.class.php
[CODE]$StorageNode = current($this->FOGCore->getClass(‘StorageNodeManager’)->find(array(‘isMaster’ => 1,‘isEnabled’ => 1,‘ip’ => $this->FOGCore->getIPAddress())));[/CODE]

Are you sure its not a firewall issue between subnets?

[quote=“irishfoguser, post: 35553, member: 25364”]mount /dev/md0p1 /images worked no idea what the p1 means but thanks.[/quote]
p1 means partition 1

[CODE] * Setting up and starting MySQL…Note: Forwarding request to ‘systemctl enable mysqld.service’.
Failed to issue method call: No such file or directory
OK[/CODE]
Note to developers, this is an issue in all systemd systems. Link to various solutions pasted below, it involves a simple systemd init script. I will try and roll my own, and post the results here, but you may choose to go in a different direction. Also possibly just changing it to “systemctl enable mariadb.service” would work as well.

[quote=“Jose Antonio Sanchez, post: 35452, member: 25349”]Correct… on Ubuntu I did:

[INDENT=1]initctl list[/INDENT]
[INDENT=1] [/INDENT]
and found no FOG services at all… Which is weird (or the services should be listed elsewhere???), but I have already imaged a few labs with Ubuntu 14.04 with Multicast no problem… well, tftpd had to be restarted and on another standalone Ubuntu 14.04 box dhcp had to be started manually…

Seems like CentOS and Ubuntu keep having service startup problems…[/quote]

Ubuntu 14.04 and CentOS 7 are both not recommended for production fog systems at this point. initctl seems like a systemd thingy, which shouldn’t work on Ubuntu. Could be wrong on that, I’ve personally never used it.

On a fun note, here’s the logic behind the exception on my multicast.log printout. Working on figuring out what’s going wrong with that.

[CODE]$StorageNode = current($this->FOGCore->getClass(‘StorageNodeManager’)->find(array(‘isMaster’ => 1,‘isEnabled’ => 1,‘ip’ => $this->FOGCore->getIPAddress())));
if (!$StorageNode || !$StorageNode->isValid())
throw new Exception(sprintf(" | StorageNode Not found on this system."));[/CODE]
