When i mount nfs on client,i got following errors,but all of nfs service are ready on server and client:

  3.  
  4. mount: 1831-008 giving up on: 
  5. server:/mksysb 
  6. System call error number -1.

  2. export list for server: 
  3. /mksysb (everyone) 
  4. [server@root:/]l***c -g nfs

  14. Subsystem         Group            PID          Status  
  15.  portmap          portmap          4718748      active

  2. Subsystem         Group            PID          Status  
  3.  biod             nfs              4980920      active 
  4.  rpc.statd        nfs              4718750      active 
  5.  rpc.lockd        nfs              4915372      active

  11. Subsystem         Group            PID          Status  
  12.  portmap          portmap          5177512      active 

So,why mounted unsuccessful???

I checked the /etc/hosts file on server that couldn't find the client list in /etc/hosts.So,i added the client list to /etc/hosts file on and mounted again then success.

  1. # mount server:/mksysb /mnt 
  2. # mount |grep nfs 
  3. server /mksysb          /mnt             nfs3   Jun 15 15:17
