Description Alan Olsen 2003-10-25 06:30:31 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4) Gecko/20030807

Description of problem:
H have a large file server that has four drives exported to the subnet I am on.
 On my Redhat 9 box, I mount all of those drives.  Then if I move files from one
exported file system to another (from one drive to another over the NFS mount)
the system will lock hard.  No messages in syslog.  No messages in syslog on the
other machine.  The system that is being mounted is fine.

This is consistant behaviour.  Sometimes I will get hangs when transfering large
quantities of files, but sometimes not.  Mount to mount kills the system dead.

The firewall is turned off.

Version-Release number of selected component (if applicable):
kernel-2.4.20-18.9 nfs-utils-1.0.5-1

How reproducible:

Steps to Reproduce:
1. mount -t nfs /mnt/export1
2. mount -t nfs /mnt/export2
3. mv -v /mnt/export1/big-mess-o-files /mnt/export2

Actual Results:  Locks the system.

Expected Results:  Should move the files.

I was unable to reproduce this problem with a more recent kernel
so I' closing this as fixed in current release.
