Red Hat Bugzilla – Bug 435426
test5 basic connectathon tests fail between RHEL5.1 and AIX 6.1.0 SP2
Last modified: 2014-05-21 13:14:45 EDT
Description of problem:
Having a configuration in which the server is RHEL5.1 Gold and the client is
AIX 6.1.0 SP2, when I run the test5 basic command (-b) of the connectathon suite
on AIX after doing a NFSV4 mount I get the following errors:
./runtests -b -t /mnt/nosec/test5
Starting BASIC tests: test directory /mnt/nosec/test5 (arg: -t)
./test5: read and write
./test5: (/mnt/nosec/test5) 'bigfile' has size 1048576, should be 0
basic tests failed
Version-Release number of selected component (if applicable):
Steps to Reproduce:
We have the error because the asked TRUNCATION is ineffective. If we suppress
the TRUNCTATION in the test5, it works.
On the AIX side, open and truncate the file are done all at once. but
linux looks to split it into two operations, it opens first and then truncate.
Another analyse on the AIX side gives the following:
>At this point the file size is 1048576.
>>The client send the following compound request over to the server.
>>OP_OPEN, with size of 0.
>>OP_NVERIFY, with the file verifier when the file size is 1048576.
>>The server reply with
>>OP_PUTFH --- NFS4_OK
>>OP_OPEN --- NFS4_OK
>>OP_NVERIFY --- NFS4ERR_SAME
>>One would think that if server return NFS4_OK for OP_OPEN that OP_OPEN

The file system on the linux server is ext3.
