Node registration failed in 1.3.0-RC30

[Maorui2k]

Server

• FOG Version: 1.3.0-RC30
• OS: Ubuntu 16.04

Client

• Service Version: Not installed yet
• OS: Windows 7 Pro

Description

I tried to register the node via iPXE, but failed at the last moment.

The node’s screen showed few lines of “Attempting to send inventory…failed” and “Rebooting system as task is completed”. And then the node just hung there.

The server syslog has following lines:
Dec 9 17:00:46 relay FOGPingHosts[11744]: PHP Fatal error: Uncaught Error: Cannot unset string offsets in /var/www/fog/lib/service/pinghosts.class.php:180

Updated to RC36, and both full & quick registration worked as expected!

[Tom Elliott]

I don’t follow.

You’re trying register a node into fog? (Do you mean a host, or an actual FOG Storage Node?)

The error log you posted has nothing to do with host registration.

[Wayne Workman]

He means a host.

[Tom Elliott]

@Wayne-Workman How do you know that?

[Wayne Workman]

@Tom-Elliott because of the error he quoted, “Attempting to send inventory…failed”

[Tom Elliott]

@Wayne-Workman How do we know what the OP is trying to do?

You know for a fact that they’re trying to register a host? I don’t know that based on the information.

Maybe they’re trying to create a new FOG Storage Node thinking they need to “register it” like a normal host?

We don’t know what the OP is trying to do, which is why I asked the question of the OP.

[Maorui2k]

I meant to register a host to fog… I tried again, same result, but syslog had no error messages.

I can find the host in management GUI, but except MAC address, all other fields are empty, not sure if this is right.

[Wayne Workman]

@Maorui2k These are some DB cleanup commands, run them and share their output with us, and after you run them try to register the host again. Run these via terminal on your server.

sudo -i
mysql -D fog
DELETE FROM `hosts` WHERE `hostID` = '0';
DELETE FROM `hostMAC` WHERE hmID = '0' OR `hmHostID` = '0';
DELETE FROM `groupMembers` WHERE `gmID` = '0' OR `gmHostID` = '0' OR `gmGroupID` = '0';
DELETE FROM `snapinGroupAssoc` WHERE `sgaID` = '0' OR `sgaSnapinID` = '0' OR `sgaStorageGroupID` = '0';
DELETE from `snapinAssoc` WHERE `saID` = '0' OR `saHostID` = '0' OR `saSnapinID` = '0';
DELETE FROM `hosts` WHERE `hostID` NOT IN (SELECT `hmHostID` FROM `hostMAC`);
DELETE FROM `hostMAC` WHERE `hmhostID` NOT IN (SELECT `hostID` FROM `hosts`);
DELETE FROM `snapinAssoc` WHERE `saHostID` NOT IN (SELECT `hostID` FROM `hosts`);
DELETE FROM `groupMembers` WHERE `gmHostID` NOT IN (SELECT `hostID` FROM `hosts`);
quit

Here is the output, seems no hostID=0 record. I de-registered and re-registered, same error message. I also reinstalled the Ubuntu & fog server, the result is same.

mysql> select * from hosts;

There were some issues with registration recently (like this one) that have been fixed, can you please update to the latest RC and try again?

[Maorui2k]

Updated to RC36, and both full & quick registration worked as expected!
