2.6.3 NFS kernel warning

2.6.3 NFS kernel warning

[Nick Warne]

Hello all,

I am not registered with the list, so please CC if possible - thanks.

I am not sure if this is a problem to report (as opposed to my old 
system's problem), but I get this now in dmesg after building 2.6.3 
tonight:

nfs_read_super: get root inode failed

This is 2.6.3 mounting a NFS from an old 486 box running Linux 2.2.13 
- and the NFS processes of the same age.

The mount still works OK though; logs from the 486 report no 
warnings/errors apart from the version 3 is unknown.

But I am intrigued why it gives this warning (and the inode.c code 
seems to imply it is a fatal error, AFAIK) if it still works?

Thanks, and regards,

Nick

"mount" is probably telling the kernel that it is mounting an NFSv3
partition. When that happens, the kernel retries using NFSv2...
