Como arreglar errores de NFS y RPC

RPC: Port mapper failure – Timed out error

Si en la consola nos sale estos errores:

Normalmente al ver este error y tratar de montar el recurso nos saldra mount.nfs: Connection timed out con nuestra NFS share.

Check NFS services on NFS server

Lo primero es probar si el servicio esta activo

Si no esta corriendo o esta bloqueado debe reiniciar el servicio NSF.

Check connectivity between NFS server and client

Estar seguro que se puede llegar al servidor NFS desde el cliente usando ping y telnet a puertos como 111 y 2049

Check if RPC info is reachable from client

Si el problema es de conectividad tendremos el siguiente error mynfsserver: RPC: Port mapper failure - Timed out

Check if you can read exported share info from client

Usar el siguiente comando para saber si el recurso esta compartido.

Si todos los comando dan las respuestas esperadas, estamos listo para montar el recurso compartido.
