Description David Joo 2003-11-26 23:56:59 UTC 
Description of problem:
When IRIX server nfs exports and RHEL3 has mounted a directory, when
client s do rm -rf on a directory it will delete the contents but also
give out an error message and not delete actual directory.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1. nfs mount a directory off IRIX server 
2. rm -rf on the directory
3.
  
Actual results:
fails to remove the directory itself and returns a 525 error message

Expected results:
Delete the directory without any problem.

Additional info:
When the directory is mounted with "nfsvers=2" option, it works well.
However, if it is mounted with "nfsvers=3" then problem keeps on appears

Comment 3 Steve Dickson 2003-11-27 15:17:05 UTC 
Could you post a tcpdump file (i.e. tcpdump -w file) of this error?

Another customer running DEC Alpha 4.x is experiencing NFS problems of
a very similar nature. In the IRIX case, RHL9 could mount the share
with no additional options, and no problems were encountered. Same
with DEC Alpha. RHL9 works fine, RHEL3 hangs when any operation is
attempted in the files under the share. After remounting with
nfsvers=2, no more problems.

Steve, do you need any additional info on this one?
Comment 8 Jeff Hillman 2004-02-16 17:33:21 UTC 
I am experiencing the same issue.  We have multiple linux clients 
with different OS's, but this issue is isolated to RHEL 3.0, and we 
are running the WS version.  We are running kernel 2.4.21-9elsmp and 
the IRIX NFS server is 6.5.20f.  We are also running an IRIX NIS 
server of the same version using automount with NFS, but we removed 
NIS from the picture and verified this is with NFS.  We get Unknown 
Error 525 when trying to do the rm -rf command.

This is a known IRIX server bug:
