Hi,
Please see the following problem reported by Supriya:
rwtest03 is failing when run on a NFS environment.
Is this reproducible?
To reproduce this, mount the ltp suite using NFS and run the following
commands:
cd /opt/pFVTR/ltp-full-20070731-m64/testcases/kernel/fs/doio
export PATH=$PATH:/opt/pFVTR-temp/ltp-full-20070731-m64/testcases/bin/
export LTPROOT=/opt/pFVTR-temp/ltp-full-20070731-m64
./rwtest -N rwtest03 -c -i 60s -n 2 -f buffered -s mmread,mmwrite -m random -Dv
10%25000:mm-buff-$$ 500b:/test/growfiles/msdos/rwtest03%f
The log message she got was this:
# ./rwtest -N rwtest03 -c -i 60s -n 2 -f buffered -s mmread,mmwrite -m random
-Dv 10%25000:mm-buff-$$
