[HTCondor-users] condor mount disk problem in shell script

[åä <kan.wu@xxxxxxxxxxxxx>]

my shell script is:

sudo mkfs.ext4 /dev/vdb
if [ $? == 0 ]; then
    echo "format /dev/vdb success"
else
    echo "format /dev/vdb fail"
fi
out_dir=/data
sudo mkdir -p $out_dir
sudo mount /dev/vdb $out_dir
if [ $? == 0 ]; then
    echo "mount /dev/vdb to /data success"
else
    echo "mount /dev/vdb to /data fail"
fi

sudo chown wukan:wukan $out_dir
echo "..........." >> /data/test.txt
if [ ! -f /data/test.txt ]; then
    echo "/data/test.txt file is not exist"
else
    echo "/data/test.txt file is exist"
fi

when i run this script in condor worker machine in condor system.

the statement "sudo mount /dev/vdb $out_dir" does not work yet.

when i execute command "df -h"

the dir /data does not mount to /dev/vdb success.

but the log say it work ok.

the log content is:

format /dev/vdb success
mount /dev/vdb to /data success

What's the problem may be? but when i run this script outside of the condor system.

the script work ok.and the dir /data  mount to /dev/vdb success.
