Red Hat Bugzilla – Bug 111072
NFS version 3 shows strange error with IRIX servers.
Last modified: 2007-11-30 17:06:59 EST
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):
Steps to Reproduce:
1. nfs mount a directory off IRIX server
2. rm -rf on the directory
fails to remove the directory itself and returns a 525 error message
Delete the directory without any problem.
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

tcpdumps on the issue with nfsvers=3 option
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?
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:
