Storage Management (Usage / Slow)

[Quazz]

@ITCC You’ll need a storage group for each location and assign the image to both groups, with the main office being the main storage group so FOG knows in which direction to replicate.

Please refer to Tom’s answer instead

[Tom Elliott]

@Quazz Correction:

You need a storage group layout that’s for your locations. Nodes can be assigned to those different groups to create a kind of “load-balancing” system.

A location can be defined as a Group nodes are associated with their respective groups. If you really need to associate a particular Node for a host, you can still do so without necessarily requiring a new group as a part of that location. The only issue I see this posing is while a host may be designated to go to a particular node, other hosts might use that same node as it’s a part of the same group.

I think i have made good progress, but would like to check with you.
(watched the video)

So i want a remote site (Junior Node) to deliver images to PC’s on that site and not to the Senior Node. (also don’t want the Senior to try and pick an image from Junior Node… do i want to split the Groups?)
I’m currently not getting replication (Added note 30 mins ago)

@ITCC What OS is fog running on? I need to know to give you commands to check stuff.

[ITCC]

Debian based

[Wayne Workman]

@ITCC What is the output of service FOGImageReplicator restart and service FOGImageReplicator status and tail -100f /opt/fog/log/fogreplicator.log

[ITCC]

on the new node the status is down.
does it pull or push from master?

[ITCC]

Sorry for the small picture but this happens now when imaging anything.

Sorry foe the small view.
Says windows 7 when windows10

Execute those on the master node.

[ITCC]

i’ll complete tomorrow and reply with log output.

I want to make sure the locations don’t run from each other.
what do i need to do to make sure the Junior only takes from the server in the JS?

I ask as my StorageGroup says free 20 (19 as imaging now)

[ITCC]

i’ve noticed that the main server is sending the image to the node and then the node is downloaded the image to machines that are not on the JS site. (this image is also not replicated to the node, in this example)

[Quazz]

@ITCC You’ll probably want to use the location plugin.

[ITCC]

on the video it states that selecting a host location “locks” the machine to that server.
This doesn’t seem to be the case.

Please advise.

[ITCC]

Location plugin installed, just trying to configure not to use WAN for anything other than replication.

[Tom Elliott]

@ITCC The image I see says Junior is the node transmitting data.

I don’t know what the exact layout is. If Senior and Junior nodes are part of the same group AND the location is only defined to use the Group, AND the hosts are associated to that location, OR The hosts are not associated to the location, the imaging will happen in a load balanced mode.

I guess I’d need to see an example of the tasking, and the host with its location setting and the location definition.

[ITCC]

Senior is master
Junior is Node
imageA set not to replicate (holds Senior Image)
imageB set for replication
Replication complete

ImageA&B members of DefaultStorageGroup

Storage Management - SS - Group = Default
Storage Management - JS - Group = Default

[ITCC]

when i image a PC in SS the image goes VIA the JS NODE and then to the host.

[Lee Rowlett]

@ITCC to setup how you want so no image goes across the wan but replication, setup like below (Be mindful you will have no resillience and if JS is busy for example and you want to image a machine at JS it will wait rather than use SS - which by the sounds of things is how you want it to work anyway)

Storage Group Definitions:
Storage Group - SS
Storage Group - JS

Storage Node Definitions:
Storage Node - SS - In Storage Group SS
Storage Node - JS - In Storage Group JS

Location Definitions:
Location SS - Storage Node - SS - Storage Group - SS
Location JS - Storage Node - JS - Storage Group - JS

Image Definitions:
ImageA - Storage Group - SS AND JS
ImageA - Storage Group - SS AND JS
make sure you tick whichever is primary (that you will upload your image to and want replication to come from)

so Location JS will only have Node JS available and vice versa.

You will be utilizing the use of Group to Group Replication which @TomElliott awesomely implemented sometime ago.

Whenever you upload an image, whatever location you choose will be the node it uploads to, just make sure you do it to whichever you set as primary otherwise you newly upload image with be overwritten.

Hope this helps
