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
Jun 13 07:54:01 sturgeon kernel: call_verify: server requires stronger
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
and after the ls command
Jun 13 07:55:08 sturgeon kernel: call_verify: server requires stronger
Jun 13 07:55:26 sturgeon last message repeated 10 times
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.
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.
