Iscsi Storage connection with the opennebula

[FrancJP (Francisco Picolini)]

Hello @Nyi_Shin,

The steps are described in the documentation already shared before:
https://docs.opennebula.io/6.10/open_cluster_deployment/storage_setup/iscsi_ds.html

There you have the info on how to create the image datastore, the steps to follow, and even a warning on the same comment that you made:
“As this Datastore is just a container for existing devices, images does not take any size from it. All devices registered will render a size of 0 and the overall devices Datastore will show up with 1MB of available space”

There are also other topics in the forum about this that might help you:

Opennebula iSCSi Datastore Capacity at 1MB

Hi All, I have recently deployed Opennebula Front End Server on top of KVM ( on Ubuntu 20.04 ).

Any recommendations ? Appreciate your help on this. regards Sagar Versions of the related components and OS (frontend, hypervisors, VMs): Steps to reproduc…

Help with iscsi_libvirt datastores

Hey, thank you two for your answers. What a pity! @hangar.hosting With NFS I wanted to try it next. @nicolas_belan I see your approach as meaningful, to use the “image datastore” via filesystem like “shared mode” and for the “system datastore” using LVM. But what I do not quite understand at LVM, the nodes must also be directly connected to the storage? Because my thought is that I would connect the storage via iSCSI (open-iscsi) to the host with the running front-end and use it for the …

But again, check the documentation, and let us know where you are stuck.
