Description Suzanne Hillman 2005-03-30 18:17:18 UTC
+++ This bug was initially created as a clone of Bug #138775 +++

From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
NFS mounts can be performed in the foreground, or in the background.
Foreground mounts are tried once, and will fail immediately if there
is any problem.  Background mounts allow the mount command to fork
a process if the first mount attempt fails that will run in the
background until the mount request succeeds.

Sometimes it is desirable for foreground mounts to retry, as well.
For example, a busy NFS server may drop a mount request, in which
case the mount command on the client should retry a couple of
times before giving up completely.

Version-Release number of selected component (if applicable):
mount-2.11g-6

How reproducible:
Sometimes

Steps to Reproduce:
1. Try an NFS mount request with the "fg" option against a very busy 
NFS server
2.
3.
    

Actual Results:  If the server drops the request, the mount command 
will exit with an error.

Expected Results:  If the server drops the request, the mount command 
should retry the requests a couple of times before giving up.

Additional info:

Oracle has hit this problem, and would like it addressed in RHEL AS 
2.1 and in RHEL 3.0.

The RHEL4 mount command already does do retransmissions
