On my SLES 10, SLES 11, and CentOS 6 servers, I'm able to list information about each NFS mount via
nfsstat -m, e.g.:
/usr/local from nfssrv1:/vol/foo Flags: rw,relatime,vers=3,rsize=65536,wsize=65536,namlen=255,hard,nolock,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=blah,mountvers=3,mountport=4046,mountproto=udp,addr=blah
We've got some older SLES 9 servers running kernel 2.6.5, and they report back "invalid option -m" when I try that command, so its not supported on the older nfs clients. How can I find out what flags are being used on these servers?
My goal is to compare the default mount options between servers to troubleshoot some NFS issues in our environment.
