Hi, NFS hard mounts should not help with sanlock. It should just kill the VMs after 60 seconds same as a soft mount. The sanlock timeout: I asked RedHat support about that in a case for my RHV environment. They said this should not be changed.
Only thing that came to my mind: disable storage leases in case of planned storage maintenance.
