Reattempting to update database...Failed

Tywyn

Hi everybody,

running fog 1.5.2 and today I tried to clone 12+18 computers.
Imaging itself went fine but when the clients tried to reconnect to update the database after the cloning, they all came to this point:

Apache errorlog:

[Tue Aug 07 12:37:08.653642 2018] [proxy_fcgi:error] [pid 2669] [client 10.10.11.63:48862] AH01071: Got error 'PHP message: PHP Notice:  A non well formed numeric value encountered in /var/www/html/fog/status/bandwidth.php on line 109\nPHP message: PHP Notice:  A non well formed numeric value encountered in /var/www/html/fog/status/bandwidth.php on line 109\nPHP message: PHP Notice:  A non well formed numeric value encountered in /var/www/html/fog/status/bandwidth.php on line 110\nPHP message: PHP Notice:  A non well formed numeric value encountered in /var/www/html/fog/status/bandwidth.php on line 110\n'

After this the fog gui also did not react anymore.
Had to reboot the fog-server.

Second try resulted in the same behavior.

Any ideas?
Thanx in advance, Rainer

OK there are two things you need to do.

Upgrade to at least FOG version 1.5.4
There are some tweaks that you need to do to 1.5.4 to make FOG happy.

Lets assume this is the issue we’ve found after FOG 1.5.4 has been released.

Change to the /etc directory from the fog server linux command prompt.
Search for www.conf file. It can be in a number of locations depending on what version of php is installed. Use this command.
find /etc -name www.conf (hopefully you will only find one)
Edit that file file and ensure these settings are accurate. Don’t just add them since all should be there except php_admin_value[memory_limit] = 256M you will need to add that entry.

php_admin_value[memory_limit] = 256M
pm.max_requests = 2000
pm.max_children = 35
pm.min_spare_servers = 5
pm.start_servers = 5

Save and exit your text editor.
Reboot the fog server.
See if that fixes what is wrong. You really should only see this strangeness under heavy load, but I guess it might show up sooner under certain conditions.

@george1421 Hi,

thanx for your advice. Tried to update. Here is what I did:
For the previous installation of 1.5.2:

cd /root
git clone https://github.com/FOGProject/fogproject.git
cd /root/fogproject/bin
./installfog.sh

Now for the update to 1.5.4:

cd /root/fogproject
git pull https://github.com/FOGProject/fogproject.git
cd /root/fogproject/bin
./installfog.sh

The install fails. Here is the errorlog:

@tywyn What version of ubuntu are you using? It appears that third party library is no longer available.

Tywyn

@george1421
~$ cat /etc/issue
Ubuntu 16.04.5 LTS \n \l

george1421

@tywyn This appears to be a ubuntu issue. A quick google-fu shows up quite a few posts with the same error.

I’m a rhel not debian guy so I can only post what I found.

Try to add these repositories your self by hand with:

sudo add-apt-repository ppa:ondrej/php
sudo add-apt-repository ppa:ondrej/apache2
sudo apt-get update
sudo apt-get upgrade

Then rerun the installer.

@george1421

Unfortunately does not work either:

# add-apt-repository ppa:ondrej/php
Cannot add PPA: 'ppa:~ondrej/ubuntu/php'.
ERROR: '~ondrej' user or team does not exist.

@Tywyn Could be a proxy or locales issue:

It was a proxy-issue. I have had http_proxy environment set, but I did not have https_proxy.
Fixing that I ran into a timeout concerning a connection to a key-server.

gpg: requesting key E5267A6C from hkp server keyserver.ubuntu.com
Error: retrieving gpg key timed out.

So I decided to add another NIC to bypass the proxy and connect directly to the internet an so the install went through.
There still remain 3 questions concerning the update process:

Installscript says:

   # It is not recommended that you install this on a production system #
   #        as this script modifies many of your system settings.       #

when I have a production system running fog, which method shall I use then, if not running install-script?

Accessing the url provided I cannot see, where I can install/update my database schema

 * You still need to install/update your database schema.
 * This can be done by opening a web browser and going to:

   http://10.10.11.63/fog/management

 * Press [Enter] key when database is updated/installed.

Having done an update without changing anything in the config, but adding a second NIC with a new default gateway: Do I have to bother about the error-message below?

* Setting up and starting DHCP Server......................... !!! No router address found !!!
!!! No dns address found !!!
OK

What this means is, be careful when you install FOG on a server that has any other services running in production. For example if you have a web server running on this system, running a FOG installation can break the other website’s apache configuration.

After the upgrade which version do you see in the blue cloud on the web UI? Just wondering. From version to version there might be DB schema updates but I am not sure if there were any from 1.5.2 to 1.5.4, possibly not.

Please post your FOG DHCP config here so we can have a look (/etc/dhcp/dhcpd.conf).

@Sebastian-Roth
On the dashboard I can see in the lower right corner: 1.5.4

@all: Thanx for your help

Quazz

@tywyn Please fill in the variables

routeraddress='yourrouterip'
plainrouter='yourrouterip'
dnsaddress='yourdnsserver (possibly router)'
dnsbootimage='yourdnsserver (possibly router)'

in /opt/fog/.fogsettings

Assuming you want FOG to handle DHCP of course…

If not set

dodhcp='N'
bldhcp='0'

in /opt/fog/.fogsettings

@quazz said in Reattempting to update database...Failed:

dnsaddress=‘yourdnsserver (possibly router)’
dnsbootimage=‘yourdnsserver (possibly router)’

Hi,

thank you for your hint. 2 remarks:

I am struggeling with the documentation here: https://wiki.fogproject.org/wiki/index.php/.fogsettings#dnsaddress
It says that the parameter dnsaddress is used for dhcp setup. What does that actually mean? Is this value put in /etc/dhcp/dhcpd.conf as option domain-name-servers ipadress;

Same documentation says, that dnsbootimage is no longer used?

Quazz

@tywyn That’s correct on both accounts. It doesn’t hurt to fill it in, but if you’re on 1.5 you can ignore dnsbootimage indeed.

The DHCP server needs to be able to point clients to a local DNS server so that they know where to look.

Tywyn

Thanx.
The thread can be marked als solved. Can I do this somewhere or can just a board admin do that?
