Description

This issue was created by maloo for Chris Horn <[e-mail]>

This issue relates to the following test suite run: https://testing.whamcloud.com/test_sets/266b7a77-975d-473d-963d-f78a22e7209f

test_1 failed with the following error:

Timeout occurred after 65 mins, last suite running was runtests

Maloo tagged this failure as LU-13065, but it looks different to me.

The last lines in suite log show us unmount clients, not OSTs as in LU-13065:

echo Stopping client \$(hostname) /mnt/lustre opts:;
lsof /mnt/lustre || need_kill=no;
if [ x != x -a x\$need_kill != xno ]; then
    pids=\$(lsof -t /mnt/lustre | sort -u);
    if [ -n \"\$pids\" ]; then
             kill -9 \$pids;
    fi
fi;
while umount  /mnt/lustre 2>&1 | grep -q busy; do
    echo /mnt/lustre is still busy, wait one second && sleep 1;
done;
fi

console log for client 2 (trevis-53vm2) shows hung mount.nfs tasks:

At a quick glance, I don't see anything wrong with Lustre
