Getting confused with the linux nfs versions?

Hi all

I am using RHEL 5. I used mount filesystem from solaris to my linux as well as from my linux to other linux and solaris systems. By default i didnt mention any nfs version at the time of mounting. Now i just want to know which version i am using ? Here are some things where i put concentration. Please take a look and explain me if u can.

[root@lux08 nfsfs]# cat /proc/fs/nfsfs/servers
v3 0acd110a 801 1 lm01
v3 0acd11ed 801 1 lux07

what does v3 means?

[root@lux08 nfsfs]# rpm -qa |grep -i nfs

whether it is indicating that i nfs version 1.0.9 is installed or else?

[root@lux08 nfs]# cat /proc/fs/nfs/exports
# Version 1.1
# Path Client(Flags) # IPs
/e403 integ12(rw,no_root_squash,sync,wdelay,no_subtree_check)
/users *(rw,root_squash,sync,wdelay,no_subtree_check)

here again it is version 1.1?....

I don't use RH but I do use 'NFS'.

Man is your friend!

excerpt from 'man nfs';

nfs - nfs and nfs4 fstab format and options
The fstab file contains information about which filesystems to mount where and with what options. For NFS mounts, it contains the server name and exported server directory to mount from, the local directory that is the mount point, and the NFS specific options that control the way the filesystem is mounted. Three different versions of the NFS protocol are supported by the Linux NFS client: NFS version 2, NFS version 3, and NFS version 4.
From the above you should identify what 'v3' is.

I suggest that you read the rest of the 'man' page.
