Troubleshoot at packet level using the following command
#tcpdump -ieth0 -vv -nn -X host 10.9.1.1
- Add entry to /etc/exports file (ON NFS SERVER01)
# <NFSshare dir> <ip address to allow (optional parameters)>
/archive 10.9.1.0/24(no_wdelay,rw,async)
/archive/shareHL7 10.9.1.9(rw,sync) 10.9.1.11(rw,sync) 10.9.1.12(rw,sync) 10.9.1.0/24(ro,async) 10.9.1.8(rw,sync) - Test if the share is active on the server
Client01:# showmount -e server01 - On NFS Client01 (Open /etc/fstab file)
# Server:/<dir>/ <mountpoint> <type> <optional parameters>
NFSSERVER01:/archive/shareHL7 /archive nfs rw,hard,bg,tcp,nfsvers=3,rsize=32768,wsize=32768 0 0 - Allow hosts access TCP (/etc/hosts.allow)
Add following line
portmap: 10.9.1.8 , 10.9.1.9 , 10.9.1.11 , 10.9.1.12 - Re-read exports file
You should run the command exportfs -ra to force nfsd to re-read the /etc/exports file
ISSUES: mount to NFS Server failed: RPC Error: Program/version mismatch (retrying).
