From Bugzilla Helper: User-Agent: Mozilla/4.61 [en] (X11; U; Linux 2.2.12-20 i686) Description of problem: the nfs partition appears to mount according to the 'df' command, but the 'ls' command show an empty directory. The following shows up the /var/log/messages: Jun 13 07:54:01 sturgeon kernel: call_verify: server requires stronger authentication. Jun 13 07:54:01 sturgeon kernel: NFS: cannot retrieve file system info. Jun 13 07:54:01 sturgeon kernel: nfs_read_super: get root inode failed Jun 13 07:54:01 sturgeon kernel: nfs warning: mount version older than kernel and after the ls command Jun 13 07:55:08 sturgeon kernel: call_verify: server requires stronger authentication. Jun 13 07:55:26 sturgeon last message repeated 10 times How reproducible: Always Steps to Reproduce: 1. mount sunbox:/home /home 2. df /home 3. ls /home Actual Results: 'ls /home' showed an empty directory Expected Results: we should see a list of user directories. Additional info: This machine has a single processor and was configured as a workstation with almost everything installed.
I suspect the server is expecting some flavor of secure RPC for filesystem access, but not requiring it for mounting the filesystem. Currently, Linux does not have support for secure RPC. Reclassifying under "kernel", which implements the NFS client functionality.
