I'm mounting a NFS filesystem on my machine. How do I figure out what version of the NFS protocol the server uses? I don't have access to the NFS server machine, but I do have root on my client machine.
Is there anything I can run on my client machine to identify what version of the NFS protocol is being used by the server, or what versions it supports?
I wasn't able to find any useful information in
/var/log/messages or kernel debugging output (
I have tried running
nfsstat, but I'm not sure if it is giving me any useful information. However, when I run
nfsstat -s to request information about the server, I don't see anything useful:
# nfsstat -s Server rpc stats: calls badcalls badfmt badauth badclnt 0 0 0 0 0
When I run
nfsstat -c to request information about the client, I do see some information about
Client nfs v3, but I'm not sure how to interpret this. Does this tell me anything about the protocol being used between my client machine and the NFS server? Does it mean I am currently using v3 of the NFS protocol? Does it tell me anything about what versions of the NFS protocol the server supports, e.g., NFS v4?
