FOG Registration Error. Hostname with that name already exists
-
@Wayne-Workman
That might help. How do i delete just this host from mysql?Why does FOG seem to be “defaulting” to this host during the Full Host Registration Process?
I did a query on the table and FOG appears to be overwritting the host in the “hosts” table again from looking at the “hostCreateDate” field
-
@Wayne-Workman
I deleted that host from both the hosts table and the hostMAC table in mysql. I am still getting the same error when attempting to Register a Host -
I was able to resolve this issue by deleting all (10) hosts with a hmID = 0
-
Now, The issue is happening again!!
-
@Tom-Elliott This is what i have done. I started by deleting each host individually. It looks like 4 hosts found there way into having a hmHostID of 0 between yesterday morning and now? I ended up deleting the remaining two hosts with the hmHostID of 0 to resolve the problem for now.
Any Ideas on how this is happening?

@cojohnson you willing to try the working RC 11 to see if it’s working better?
-
I had 3 more hosts in mysql with a hmHostID of 0 within the last 45 minutes.
I was trying to register a host and first got an "Truncated " error followed by my normal error. I immediately tried a reboot and got my hostname error. I dont know if this will assist in the troubleshooting process. I figured it was worth a mention!

@cojohnson and @Tom-Elliott, that hostname that was inputted is only 12 characters long, not 15.
Also, I’ve got this thing I wrote a while back that monitors hosts in FOG, we can modify it to keep an eye on the hosts with 0 as an ID and figure out exactly when it’s happening. I’d just need some time with you via Join.me. Also, do try RC-11 as Tom suggested. If you message me via the forums chat, I can give you steps on how to do that.

@cojohnson Can you run these SQL queries in MySQL please, and give us the results?
mysql -D fog SELECT `hostID`, `hostName` FROM `hosts` WHERE `hostID` = '0'; SELECT * FROM `hostMAC` WHERE hmID = '0' OR `hmHostID` = '0'; SELECT * FROM `groupMembers` WHERE `gmID` = '0' OR `gmHostID` = '0' OR `gmGroupID` = '0'; SELECT * FROM `snapinGroupAssoc` WHERE `sgaID` = '0' OR `sgaSnapinID` = '0' OR `sgaStorageGroupID` = '0'; SELECT * from `snapinAssoc` WHERE `saID` = '0' OR `saHostID` = '0' OR `saSnapinID` = '0'; quit -
@Wayne-Workman Thanks, I am available today whenever you get a chance to have a conversation. Here are the results of the queries you wanted me run. I deleted these entries and will update the thread if the issue arises again
-
@cojohnson can you please try working RC 11 after cleaning up the db? I’m pretty sure that it will address the random 0 entries too.
-
@Tom-Elliott I will do the upgrade! Thanks for all of your hard work!
-
@Tom-Elliott
The issue just started happening again! On RC11.
-
@Tom-Elliott
I deleted the Hosts from the table and delete a unused Storage Group. So i am functional right now and will update the thread if i have any more problems.Do you have any ideas?
-
@cojohnson Nope. Working RC 12 has some improvements though. If you want to try that.
I’ve not been able to replicate the issue myself. Then again, I wasn’t able to replicate it in RC-10, though I did find what was causing it.
-
@cojohnson Can you try these commands? This is just out of pure curiosity on my part, but could potentially reveal an issue.

@cojohnson All of those are dirty entries that are either hosts with no MAC, or MACs with no host, or associations with no host. They can all be deleted with the below commands. Do me a favor please, and in about a week from now, re-run the earlier commands I asked you to run ( the select ones) and see if there is any output again or not. Also pinging @Tom-Elliott so he’s aware of this.
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`); -
I ran those commands again today after troubleshooting why all computers of one model “HP Stream 11” are not getting their hostnames changed by the FOG Client.
Note I still get the “Hostname with that name already exists” error when there are entries for the command:
