Looking forward to trying this myself.

Hi,

Under the installation folder below data and sites, check the json files for any errors. Also check data\jobs. If it still fails & need assistance, feel free to send the logs to [e-mail].

I attached screenshot from my deployment for reference.

Thanks,

Yes, the feature is on development and should be out shortly (in 1 or 2 months).

[fading shard]

There's nothing in the "data/sites" folder. All the logs are 0 bytes (only the service_setup.log is there but no error messages in there, looks successful).
Send you an email.

[fading shard]

Ok it's working now. Was some certificate error (the cert of the backend service was not trusted).
@wraith mica Send many thanks to NiMo please!

[little hill]

I’ve tried to get him in here previously. He would love this place and have a lot to contribute.

[woeful ingot]

But also don't want to distract him from what he's doing. Go NiMo go.

@Proxmox users
Have anyone managed to get discard working when running Proxmox with NFS? Feels like I've tried everything and can't get the qcow files to shrink after they have grown. Only thing that works is a disk migration 😥

[reef urchin]

The NetApp documentation says that ONTAP does not currently support the DEALLOCATE command with NFSv4.2. It also mentions an RFE that this has been requested.

[onyx scaffold]

Thanks Jeff! Found the KB aswell. Still learning to navigate NetApp docs & KB pages, first time NetApp user since a couple of weeks ago.

[cobalt tangle]

@wraith mica we are desperately waiting for full vmware to proxmox migration with NetApp Shift. Cloud you please let me know when you have an ETA? That would be so nice 🙂

[wraith mica]

Just curious, how many VMs are they planning to migrate? Early option is around Mid March.

[cobalt tangle]

Around 2000 VMs maybe a little more

[static zinc]

What's the latest on this? OnTAP support while running on Proxmox is the only think hold my team back from migrating everything off of VMware.

[clear palm]

Can it be that ONTAP Tools 10.5P1 doesn't like ONTAP Cluster names like "na-cluster02" ? It shows "Invalid hostname og IP address" when I try to add the storage backend (from vSphere plugin)... it I try the IP address it tells me "The certificate is invalid or is missing the 'Subject Alt Name'"..... hmmm this all worked in ONTAP Tools 9 BTW... isn't that just great?

...same error if I try it from the Tools Manager GUI...

After disabling the "certificate validation flag" in the maint menu as described in a KB.. and waiting 15 mins. it was finally able to add the clusters... I tried to add them from the ONTAP Tools manager GUI... and associate it to a vCenter... yet I cannot see it in the vCenter plugin?

[little hill]

@wraith juniper any thoughts here?

[robust moth]

did you check the certificate and that it really contains the correct SAN entries?

[clear palm]

Yeah they did... as mentioned I fixed it by logging into the console as maint... then selecting 1, and 3 to clear the cert. validation flag... then I guess 100 microservices had to restart 😉 Because it didn't work right away... but ather 10-15 min. it worked... Maybe it's me... but I still don't understand how the setup from inside the Tools Manager GUI is supposed to work? I add the vCenter... then I tried to add a few clusters (which had existing datastores in the vCenter) as Backend Storage... and assigned the backend storage to the vCenter... then did a bunch of rescans and discoveries... but they never show up inside the vSphere plugin... I ended up removing the backends and adding them from the vSphere plugin, and then it was able to discover the datastores.... I am sorry to say, but I think this is close to the worst software NetApp has done yet... I have a customer where we have a case on upgrades gone bad from 10.2 to 10.3 to 10.5... the initial case was started 6 months ago.. sadly we cannot just re-install because we have protection setup as SMAS on the cluster, and 10.3 and/or 10.5 doesn't pickup on protections done in 10.2.... so it's painful going with 1-2 developers at each bi-weekly remote session... kubernetes is just painful when you have to debug issues... 🙂 But as least this new install ended up working after the fix...

[robust moth]

yeah but disabling certificate validation is just a workaround, the original issue with the certificate still persists

[wraith juniper]

I've heard it's being looked into, but I'm not familiar with the OTS roadmap.

[wraith juniper]

Are you trying to use secure multitenancy with OTV? If not, the way you want to add storage to OTV is via the vCenter UI, not the manager UI.

Regarding certificates, the default ONTAP self-signed cert lacks any SAN entries, so we have a KB article on how to generate new self-signed certs using a standard Linux CLI: https://kb.netapp.com/data-mgmt/OTV/VSC_Kbs/How_to_generate_a_self-signed_certificate_with_Subject_Alternative_Name_(SAN)_for_ONTAP_use_with_ONTAP_tools_for_VMware_vSphere_10.5_and_later

Modern certificate validation requires the server hold SANs, and as a best practice, I recommend you have two SANs that resolve to each other. - a DNS SAN, and an IP SAN.

[viscid nacelle]

Is it right that to uninstall OTV you have to removed all vms from the data stores , surely this just a management tool and I should be able to remove without impacting VMs

[robust moth]

depends on whether you're using vVols or not, I guess

[viscid nacelle]

No vVols just nfs mounted flexvols

[glossy vortex]

I’m looking to try NetApp Shift, but unfortunately I don’t have access to a proper NetApp lab environment for testing at this time.

When adding a new site, do I need to use NetApp cluster administrator credentials, or can I use an account scoped to a specific SVM, such as vsadmin?

I’m a bit hesitant to use cluster admin credentials for this purpose.

[glossy vortex]

nevermind, it seems to work
just didnt take for the first few tries

probably some typo somehwere

[frank crystal]

ok silly question that might have already been answered but is there any kind of document stating minimum ontap, esxi, and nutanix versions for using the shift toolkit with nutanix... have a customer keen on using it

[robust moth]

here

Nutanix probably uses kvm with qcow2 disks? if so, you'll have to import them manually after converting

[frank crystal]

It's going to be first party soon:
https://www.netapp.com/blog/modernize-virtualization-nutanix-partnership/

[sacred atlas]

You would have have to use Nutanix Move to migrate from esxi to AHV

[robust moth]

I don't think this is about Shift... it's more about adding ONTAP storage to Nutanix clusters

but yeah, they have multiple other conversion-types on the roadmap for shift, just no commitments yet. I'm sure vmware->ahx is on that list somewhere 🙂

[swift sundial]

Nutanix's MOVE and NetApp's SHIFT are being intergrated into each other.

[eternal wagon]

I hope it’s gonna be officially named
“Move n’ Shift”

[rotund tendon]

Hi @wraith mica , any chance I could get a progress update on the addition of Proxmox migration into the Shift Toolkit?

[onyx scaffold]

It's live in the latest version https://docs.netapp.com/us-en/netapp-solutions-virtualization/migration/shift-toolkit-migrate-esxi2proxmox.html

[onyx scaffold]

To give a bit more feeback - we have tested this and decided to keep using Shift to only do the conversion from VMDK to QCOW2. The full migration, that does work nicely, does not allow you to specify a bunch of setting on the newly created VM that we would like to set prior to even booting the VM in proxmox. E.g Machine Type is default, while we use q35. Disks are created without any options and so on. It's a step in the right direction but not yet there. The missing features should be easy to add tho 😄

[rotund tendon]

I hope to start using this over the coming months so thanks for the progress you guys have made so far

[onyx scaffold]

Im just a user like you. All credits to the devs working on Shift 🫶

[shrewd stone]

+1 for the VM setting features

[little hill]

[shrewd stone]

That looks good, love the integrated CVE scanner too

[boreal thunder]

Did SnapManager for Hyper-V get killed off? All the documentation links point me to NetApp Backup and Recovery now?

[little hill]

All of the SnapManagers were consolidated a few years ago into SnapCenter, and to the best of my knowledge, all of that is being rolled up into Console Backup & Recovery. Let me poke around and get a real answer for you, or confirm my hunch.

[fading shard]

https://mysupport.netapp.com/info/communications/ECMLP2884118.html
EOS was Nov-2025.

Backup & Recovery now supports Hyper-V so I would check that out. There is also more stuff coming for customers who don't like the cloud and want something more "local".

[fluid kernel]

Are you saying Console Backup & Recovery will replace SnapCenter or is the plan still two concurrent products?

[glossy vortex]

I find it surprising that NetApp Backup and Recovery does not support Proxmox

[reef urchin]

It might support Proxmox. What is your configuration?

We had some questions about KVM support and SnapCenter that would apply to Proxmox. I had a discussion with the PM team and got a documentation fix. See the. "other hypervisors" section here: https://docs.netapp.com/us-en/snapcenter/protect-sco/reference_storage_types_supported_by_snapcenter_plug_in_for_oracle_database.html#storage-types-supported-on-linux

If you need support for protection of data on a Proxmox datastore, that's different. That would require an agent that can interact with Proxmox itself for discovery and other storage management tasks. That's not easy to do. However, most virtualized environments I work with use guest-owned storage, like iSCSI LUNs or NFS shares mounted to the guest. In those cases, the use of a hypervisor is irrelevant. We should support SnapCenter and NBR in those configurations. If that applies to you, let me know. I'll talk to the PM team and see about getting a formal statement of support along the lines of what I got added to SnapCenter support.

[glossy vortex]

for datastore-level, VM-consistent backups, this is already partially possible with NetApp Storage Manager for Proxmox: create vm-consistent backups and replicate them to a secondary ONTAP system using SnapMirror.

[raw basin]

@little hill I have this question as well.

[dreamy linden]

Well replace is maybe not completly correct, right? The (I call it) "new" release as part of the NetApp Console lanch (fka BlueXP) the "Unifed" Backup&Recovery (fka Cloud Backup Service) does address many more application consitant options like NAS, RH Openshift, KVM, HyperV and K8s already, does rely on SaaS components and yet kinda overlap with SnapCenter features like VMware, Oracle or SQL consitant array based data Protection and recovery BUT always addressed hyperscalers "ONTAP options" as well plus from the beginning enabled a Cyres compliant Air-gap ONTAP to Object Storage "of your" choice solution (leveraging SnapMirror Cloud).
