Hi all,

Just in case ones needs it, in order to remove the secondary network interface from engine, you can go to:
Virtual Machines -> Hostedengine -> Network Interfaces -> edit -> unplug it -> confirm -> remove it.

It was simple...

Hi Knarra,

Then I had already enabled NFS on ISO gluster volume.
Maybe i had some networking issue then. I need to remove the secondary interface in order to test that again.

Hi Knarra,

The ISO domain is of type gluster though I had nfs enabled on that volume.
you need to have nfs enabled on the volume. what i meant is nfs.disable off which means nfs is on.

For more info please refer to bug https://bugzilla.redhat.com/show_bug.cgi?id=1437799
I will disable the nfs and try. Though in order to try I need first to remove that second interface from engine.
Is there a way I can remove the secondary storage network interface from the engine?
I am not sure how to do that, but   you may shutdown the vm using the command hosted-engine --vm-shutdown which will power off the vm and try to remove the networks using vdsclient. (not sure if this is right, but suggesting a way)

Thanx

Hi all,

When setting up hosted engine setup on top gluster with 3 nodes, I had gluster configured on a separate network interface, as recommended. When I tried later to upload ISO from engine to ISO domain, the engine was not able to upload it since the VM did not have access to the separate storage network. I then added the storage network interface to the hosted engine and ISO upload succeeded.
May i know what was the volume type created and added as ISO domain ?

If you plan to use a glusterfs volume below is the procedure :

1) Create a glusterfs volume.
2) While adding storage domain select Domain Function as 'ISO' and Storage Type as 'glusterfs' .
3) You can either use 'use managed gluster volume' check box and select the gluster volume which you have created for storing ISO's or you can type the full path of the volume.
4) Once this is added please make sure to set the option nfs.disable off.
5) Now you can go to HE engine and run the command engine-iso-uploader upload -i <gluster_iso_domain_name> <iso_file>

Iso gets uploaded successfully.


1st question: do I need to add the network interface to engine in order to upload ISOs? does there exist any alternate way?
AFAIK, this is not required when glusterfs volume is used.

Attached is the screenshot where i have only one network attached to my HE which is ovirtmgmt.

Then I proceeded to configure bonding for the storage domain, bonding 2 NICs at each server. When trying to set a custom bond of mode=6 (as recommended from gluster) I received a warning that mode0, 5 and 6 cannot be configured since the interface is used from VMs. I also understood that having the storage network assigned to VMs makes it a bridge which decreases performance of networking. When trying to remove the network interface from engine it cannot be done, since the engine is running.

2nd question: Is there a way I can remove the secondary storage network interface from the engine?

Many thanx
