Can't add "all" hosts under one group

[Hanz]

I would like to add all my hosts under one group to make resetting encryption data easier.

I’m running SVN 6321 and wanted to know if this has been addressed before updating to newest version.

[Wayne Workman]

In r6303 this works fine for me. How are you trying to do it exactly?

[Tom Elliott]

I don’t understand.

[Hanz]

@Tom-Elliott still on 6321, created group “Whole” and tried to add all 1600+ hosts to that group, but after it says the group updated successfully, there are no members in group “Whole”…Is there a limit to the amount that can be added at once ?

[Tom Elliott]

@Hanz There is, but it varies depending on the server.

[Hanz]

@Tom-Elliott any suggestions ? 8G Ram I5 proc. is what I have now. Any settings for this ?

[Wayne Workman]

@Hanz can you add a random 5 to the group successfully?

[Hanz]

@Wayne-Workman random five works fine

[Wayne Workman]

@Hanz I can probably make a SQL statement that will do the group add for you in the mean time, but we do need to get this figured out. Can you check the apache error logs and mysql error logs?

[Hanz]

@Wayne-Workman here is the apache error log from the instance.

[Mon Feb 22 08:39:23.847739 2016] [:error] [pid 5050] [client 10.72.2.46:60053] PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0, referer: http://10.72.3.50/fog/management/index.php?node=group&sub=membership&id=63

[Wayne Workman]

@Hanz ok can you try what the error suggests?

Here’s a command to find that file:

find / | grep /php.ini

[Hanz]

@Wayne-Workman sry didn’t see that error before when looking…changed it to 2500 and rebooted server…still getting same error.

[Mon Feb 22 08:39:23.847739 2016] [:error] [pid 5050] [client 10.72.2.46:60053] PHP Warning: Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars in php.ini. in Unknown on line 0, referer: http://10.72.3.50/fog/management/index.php?node=group&sub=membership&id=63

[Wayne Workman]

@Hanz Sure you got the right file? Double check for typos? It should work…

[Hanz]

@Wayne-Workman I’ve got /etc/php.ini , /etc/php.ini.rpmnew, /usr/share/doc/php-common/php.ini-production, and /usr/share/doc/php-common/php.ini-development.

I changed the first one and double checked the line to make sure it was saved.

[Wayne Workman]

@Hanz Ok then… I don’t know what is causing it then. Stand by - I’ve about got a script done that does what you want.

[Hanz]

@Wayne-Workman I could do this with phpMyAdmin right ? I dunno why I didn’t think of that. Anyways I’ll go that route, but leave this just so the devs know this is going on, at least on 6321.

Also running php 7.0 from remi

[Wayne Workman]

@Hanz This script does what you want.

# This script adds all fog hosts to the below specified group name.
# the group name is case sensitive.

groupName=My-caseSensitive-Test-group-Name

snmysqluser="$(grep 'snmysqluser=' $fogsettings | cut -d \' -f2 )"

        for i in ${hostIDs[@]}; do
                mysql -s -h$snmysqlhost -u$snmysqluser -p$snmysqlpass -D fog -e "insert into groupMembers (gmHostID,gmGroupID) values (${i},$groupID)"
