Migration of VMs from Proxmox A to Proxmox B in same cluster: Target Storage does not show up

[Scampicfx]

Hey there,

- Proxmox Server A is connected to a dedicated NFS storage A which is only available for Proxmox Server A
- Proxmox Server B is connected to a dedicated NFS storage B which is only available for Proxmox Server B

I created a cluster so that both Server A and Server B can get managed from the same web interface.

My goal is to migrate VMs from A to B.

The problem is: When right-clicking on a VM and selecting "Migrate", I do not have any option to select Target Storage. The drop down menu simply isn't there.
I tried to do a migration from A to B with following VMs:
- A VM on Server A, which is stored on local disk
- A VM on Server A, which is stored on NFS storage

Both VMs have the same problem: I can't migrate them to Server B because the Target Storage Dropdown Menu is missing.

As mentioned, both Server have their unique NFS storage which isn't shared between the hosts.

I am happy to use other methods of migrating the VMs as well. I thought doing it with "right click -> migrate" might be easy. But it looks like it is more complicated.

Any help would be appreciated! Thank you so much!

Cheers,
Chris

The problem is: When right-clicking on a VM and selecting "Migrate", I do not have any option to select Target Storage.

Is the VM up and running? The offer of a "Target storage" in the "Migrate VM" dialog is only given for running VMs.

Hey,
I tried both: VMs up and VMs offline.
Since I couldn't solve this issue until now I will try to do backup/restore method.

If anybody else comes here: My solution was to do Backup -> Restore.

Why not just allow export on nfs storage A to host B and on storage B host A also ?!?

Hey waltar, could you quickly describe what you mean by "allow export"?

 

[waltar]

Proxmox Server A is connected to a dedicated NFS storage A

So inside your dedicated storage there is an nfs export defined (mostly written into /etc/exports in linux based os) but I think was done by gui of it which allows access of server A. That should be extended to allow server B also.
Same for dedicated storage B is configured for access of server B which shoud be extended for server A also.

Shouldn't this work on CLI withqm migrate <vmId> <destHost> -targetstorage <targetStorage> anyway? If vm is running then add -online
