4. Create auxiliary scripts required for cli_user tests:

Create a file /usr/share/zfs/zpool.d/upath with this content or execute the following command:

su -
mkdir /usr/share/zfs/zpool.d
cat > /usr/share/zfs/zpool.d/upath <<EOT
#!/bin/sh
if [ "\$1" = "-h" ] ; then
        echo "Show the underlying path for a device."
        exit
fi
 # shellcheck disable=SC2154
echo upath="\$VDEV_UPATH"
EOT
sed -i '/./!d' /usr/share/zfs/zpool.d/upath

Then create a file /usr/share/zfs/zpool.d/iostat with the following content or execute the following commands:

cat > /usr/share/zfs/zpool.d/iostat <<EOT
#!/bin/sh
#
# Display most relevant iostat bandwidth/latency numbers.  The output is
# dependent on the name of the script/symlink used to call it.
#
helpstr="
iostat:         Show iostat values since boot (summary page).
iostat-1s:      Do a single 1-second iostat sample and show values.
iostat-10s:     Do a single 10-second iostat sample and show values."
script="\${0##*/}"
if [ "\$1" = "-h" ] ; then
    echo "\$helpstr" | grep "\$script:" | tr -s '\\t' | cut -f 2-
    exit
fi
if [ "\$script" = "iostat-1s" ] ; then
    # Do a single one-second sample
    interval=1
    # Don't show summary stats
    brief="yes"
elif [ "\$script" = "iostat-10s" ] ; then
    # Do a single ten-second sample
    interval=10
    # Don't show summary stats
    brief="yes"
fi
if [ -f "\$VDEV_UPATH" ] ; then
    # We're a file-based vdev, iostat doesn't work on us.  Do nothing.
    exit
fi
out=\$(iostat -x "\${VDEV_UPATH##*/}" \
    \${interval:+"\$interval"} \
    \${interval:+"1"} | tail -n 2)
     
# Sample output (we want the last two lines):

#
# Get the column names
cols=\$(echo "\$out" | head -n 1)
# Get the values and tab separate them to make them cut-able.
vals=\$(echo "\$out" | tail -n 1 | tr -s '[:space:]' '\\t')
i=0
for col in \$cols ; do
    i=\$((i+1))
    # Skip the first column since it's just the device name
    if [ \$i -eq 1 ]; then
        continue
    fi
    # Get i'th value
    val=\$(echo "\$vals" | cut -f "\$i")
    echo "\$col=\$val"
done
EOT
sed -i '/./!d' /usr/share/zfs/zpool.d/iostat

After that do the following steps:

cd /usr/share/zfs/zpool.d
cp iostat iostat-10s
cp iostat iostat-1s
chmod +x upath iostat iostat-10s iostat-1s

5. Login by user ztest and run tests

You can run tests with the special test script. The script can be created with any text editor or by executing the following command:

After running of this script you will find the log in the /var/tmp/zfstest.<ISO TIME>.txt file. It will contain information in the format that is used in Test Results.

Before running of this script you have to get IDs of tree 8-GB disks from this VM. You can do it with the diskinfo command and run the test script with these IDs in parameters (you can find IDs in the DISK column of the diskinfo output), for example:

...

Then you can disconnect in any time by pressing Ctrl-A d and connect back in the new SSH session by the command:

ztest@zone:~# screen -r
