IV46091: AIX NFSV4 CLIENT DOESN'T UPDATE LEASE TIME IF SERV LEASE CHANGES
Closed as fixed if next.
After an initial mount of an NFSv4 filesystem on AIX, the lease time of the NFSv4 server is saved off. If all the filesystems from this NFSv4 server are unmounted (on the client), and the lease time changed on the server, the new lease time value is not used by the AIX client. It'll continue to use the old value. This will result in the lease renew operations to not happen within time, and causes the lease to expire. The NFSv4 server could fail delegations and locks if leases expire.
Reboot AIX client after the lease time on the NFSv4 server has been changed.
Code changes are in a risky code path (State Manager4 module), SM4 ( State Manager4 ) architecture is very stable and making any modification on how we update the lease time would have impact on NFSv4's major functionality such as returning a delegation, lease renewing, file locking. Hence it is advisible to dropp the changes in development releases only. this issue as of now is hit only by IBM Corp ( Z/OS servers ). Code approver is also of the same openion.
This APAR is being closed FIN. This means that a solution to this APAR is expected to be delivered from IBM in a release (if any) to be available within the next 24 months.
