Hi All,
I am looking to upgrade our SVM's from NFS v3 to NFS 4.1 / 4.2. The SVM's host volumes for VMware Datastores (Vsphere 7), Linux Servers, Oracle, Linux NFS mapped storage and CIFS shares presented to Windows and Linux clients.
Our Linux infrastructure is Red Hat 7 and we are in the process of rebuilding to Red Hat 9. We have seen some NFS file locking issues in Red Hat 9 and a suggestion has been made that upgrading to NFS 4.1 / 4.2 may solve this issue.
Enabling NFS 4.1 / 4.2 looks as simple as a tick box in the SVM settings and ensuring that all Export Policies in the SVM allow for NFSv4 access protocols.
Is there anything else I need to look out for?
Is the transition to NFS 4.1 / 4.2 seamless from a client perspective?
Looking at VMWare, it appears that there wont be an impact and that NFS 4 datastores will only be used when creating new datastores.
Any pieces of advice would be welcome. It looks like a fairly simple change, but the impact if something goes wrong would be large.
Thanks,
Ben
