Hello, a customer has the following configuration: 1 server that exports a directory called /prova/dati 1 client that mounts the remote directory on the client runs a program that created and update several files. Some times the server is turn down while the client still has the remote directory mounted. Is there a fast way to know that the remote server is actualy unavailable? If he issues a write on a file, non longer served, he sees the message: NFS3 server bluff not responding still trying and the command doesn't return. Digital Unix 4.0 Thanks, Gea

My usual recommendations are "ping <server>" and "rpcinfo -p <server>". If you want to see if NFS is acutally willing to talk back to you, then "rpcinfo -u <server> nfs 3" is good. Ping tells you if the server is up at all, rpcinfo -p tells you if portmap is running and what has registered with it, rpcinfo -u or -t actually calls the service. -- <> Eric (Ric) Werme <> This space under reconstruction <> <> <werme@zk3.dec.com> <> <> [posted by Notes-News gateway] | |||||

Do you know if it is possible to have the same information from a system call that I can be used by a C program? I've tested the stat* routines with no success. Thanks, Gea | |||||

Hi You could mount soft rather than hard, and be sure you application checks I/O status returns on I/O calls, then you would find out within the NFS timeout. |
