I would be interested to know if you can use leases/delegations to solve the issue. If you can not, can leases/delegations be extended instead of proposing an new API? >From theory, the high-available NFS-Ganesha and Samba services should have solved similar problems already. IIRC Anoop CS And Soumya have been working on this mostly. If you have specific questions about the implementation in Samba or NFS-Ganesha, ask on this list and include them on CC. Also, we do have the (low-volume) integration@xxxxxxxxxxx list for discussions around integrating gfapi with other projects. There might be others that are interested in these kind of details.
