After updating from 4.2 to 4.3, users on Debian systems could no longer log in successfully. Login was ok, but the desktop did not appear immediately. It took at least 5 minutes until the users finally had their desktop.
User home directories were mounted to the Debian clients via NFS (as /home/users/USERNAME).
In the logs of both the server and the Debian client, there were indications that the NFS-lockd was not available. NFS-lockd is superfluous with NFSv4.
The clients had mounted the shares in /etc/fstab with “v3”.
Change version option in the client’s
/etc/fstab from “v3” to “v4”.
Verify the rpc service is enabled and running on the UCS server as this service is needed for NFS locking.
