Hi,
We also had a recent failures for rwtest01,02,03 and 04. Please see
below the sequence of events as well as the solution for this:

Sudeesh John Reported:
=================================================================
The test cases rwtest01, rwtest02,rwtest03,rwtest04 from ltp suite are
failing
for RHEL4U5 on x3850M2 architecture.
Software Environment:
1. "uname -a" output----

Observations :
If we provide the file size to test, then the test is passing
Example:
[EMAIL PROTECTED] doio]# ./rwtest -N rwtest01 -c -q -i 60s -f sync
1m:rw-sync-$$
rwtest01 1 PASS : Test passed

I have run the test on the machine x3500 up with 2.6.9-67.ELsmp from the
fdisk
partition then the test is passed.
--uname -a output--

rwtest01 1 PASS : Test passed

Then I created a lvm volume with ext3 file system and copied the ltp suite into
the volune and tniggered the test, the test is failing

There seems to be some problem with the SHELL of lvm volume, for which
the if
statement at line 358 of rwtest is not getting executed and not proper
parameters being passed to the test Binary.
When you want to run individual test cases manually, you should avoid using the
command line directly. Instead the below approach is recommended:
Create a File say rwtesting under ltp/runtest directory. Then copy:
./rwtest -N rwtest01 -c -q -i 60s -f sync 10%25000:rw-sync-$$
in to ltp/runtest/rwtesting file
And then run the test like:
./runltp -f rwtesting

>From my understanding this is not a problem with the shell. Hope this is a bug
in the ltp 'rwtest' test case.
My observation :
from ltp-full-20080131/testcases/kernel/fs/doio/rwtest
............
............
322 # If df is a symlink (to busybox) then do not pass the $dir and $dfOpts
323 # parameters because they don't work as expected
324 [ -h $(which df) ] && dir=""; dfOpts=""
325
326 blks=$(df $dfOpts $dir |
327 (while read fs blks used avail cap mountpoint
...........
the variable dfOpts (in #324) is seting to NULL even if the df is not a symbolic
link.(It has to be "-P" itself to get the output portable).And so the "df
$dfOpts $dir" (line #326) command is not giving a result expected by the
succeeding statements.
I have written a patch for this. I hope this will work.
