Hi,
I'm using a QNAP as storage for my host. The datastores are all connected via NFS V4. Unfortunately, I am now forced to change the name of the QNAP (old: QNAP1; new: QNAP01). This also changes the login (old: QNAP1\esx1; new: QNAP01\esx1).
My problem: How can I change the access data in the existing datastore?
Or am I forced to delete the datastore and register again?
Thanks in advance,
SleiderDE
Hello everyone,
I am replying here on behalf of all the replies. - Thank you very much!
Long story short:
Changes to the connection of an NFS datastore are not possible without the affected VMs having downtime.
This applies both to changing an IP and to changing the NFS V4 credentials.
You must therefore in any case:
Thanks again to everybody!

Try following steps:
Hello All,
This NFS v4 Datastore Name getting change in vCenter is the Well known and historic issue.
You need make Sure in the vCenter Server and vSphere the Datastore need to have the Unique name and Unique UUID
If due to any reason like power or storage outage it is getting change it means there is issue on the storage array end.
Else you can unmount or forcefully remove the Datastore and ask vCenter Sysops engineer to perform stale Datastore entries from vCenter Database (VCD) and then register back
Do let me if you need any thing else
Happy to Help

Changing the name of your QNAP storage and its associated login credentials can indeed affect your NFS connections, especially in a VMware ESXi environment. You'll need to update the NFS datastore settings to reflect these changes.
Steps to Update NFS Datastore Settings in VMware ESXi:
Backup Your Data: Before making any changes, ensure you have backups of all critical data stored on the NFS datastores.
Access the ESXi Host: Connect to the ESXi host or vCenter using the vSphere Client. Unmount the NFS Datastore: Navigate to the 'Storage' section. Find the NFS datastore connected to your QNAP. Right-click on the datastore and select 'Unmount'. This will disconnect it without deleting the data.
Update NFS Configuration: Go to 'Networking' and find the NFS settings. Update the NFS path with the new QNAP name (e.g., from /QNAP1/data to /QNAP01/data). Update the access credentials (from QNAP1\esx1 to QNAP01\esx1).
Remount the Datastore: Navigate back to 'Storage'. Add new datastore and select 'NFS'. Enter the updated NFS path and credentials. Remount the datastore.
Verify Connectivity --> Update Any Associated Services or VMs.
Downtime: This process will require downtime for any VMs or services using the NFS datastore.
