Storagenode and queues

[Wayne Workman]

@theWizard If all storage nodes are assigned to the same location and are all in the same group, there’s no point in using the location plugin. You can uninstall it in the plugin management area, then try again, see what happens.

There is because the machines that are used to build images on are set to the main server then when uploading/downloading those machines 1 slot is opened up and there is then no need to wait for replication ( we can be updating and uploading images at the same time as deploying machines with the image it will be replacing so our replication only runs once a day).
Location plugin aside if i open 1 slot on server then deploy 5 machines only 1 will start and others will be queued.

I can disable location plugin for testing purposes though no problem.

Ok disabled location plugin and set main server queue to 1, meaning there is 1 slot on main server and 5 on each of the nodes ( 26 total )
Launched two machines to image and only one started, the other sits in the queue i assume because the result of
http://fogserver/fog/service/ipxe/boot.php?mac=28:f1:0e:15:34:e8

Is trying to use the server instead of any of the storage nodes.

@theWizard Did you disable the location plugin, or completely uninstall it? Also are you sure the image you’re working with exists on the other nodes?

[Wayne Workman]

I’m going to setup a test at home to see if queuing works right. I’ll be back in a few hours.

@Wayne-Workman
Yea i checked all nodes and the images are there as they should be, like i say if i set the queue on main server to 0 it will then use a single storagenode and not any others i.e queue of 5 on node A and fire a group of 20 to deploy only 5 will start and the other 15 will sit in the queue even tho Nodes B C D have 5 slots each too.

Yea i removed it from installed plugins.

Ok, just tested this at home with 2 storage nodes both on RC-25. I put both in the same storage group and waited for replication to complete. I didn’t install the Location Plugin. I set both storage nodes to 1 maximum clients, and then I started imaging two computers with the same image.

It load balanced properly (see pictures below). So now, the question is how do you have your system setup? Can you post a screenshot of your Storage Management area like I did in the 1st picture below so we can see how you have your nodes, groups, masters, and max clients arranged please?

Thinking more on this, it could be a DB connection issue or mis-matched version issue. For all of your storage nodes, visit this URL, replacing x.x.x.x with each of their IP addresses.

x.x.x.x/fog/service/getversion.php

• All should respond
• None should give any sort of error
• All should be on the exact same version as the main server, which should be RC-25.

Output for them all should look like:

1.3.0-RC-25

@Wayne-Workman

Completed on each one no errors at all each one returning RC-25 including server

I think i cracked it, after you mentioned DB connection issues i checked everything using workbench and found fogstorage user had no schema privaleges at all ! Not sure how they would dissapear but after adding back in fog seems to be picking other storagenodes correctly.
Thank you for the help and guidance.
This can be marked as no bug but maybe helpful for others to check if they encounter issues.
