Hi!
I'm facing a weird hang in iotest 233 on my Fedora 41 laptop. When running
./check -raw 233
the test simply hangs. Looking at the log, the last message is "== check
plain client to TLS server fails ==". I added some debug messages, and it
seems like the previous NBD server is not correctly terminated here.
The test works fine again if I apply this patch:
diff --git a/tests/qemu-iotests/common.nbd b/tests/qemu-iotests/common.nbd
--- a/tests/qemu-iotests/common.nbd
+++ b/tests/qemu-iotests/common.nbd
@@ -35,7 +35,7 @@ nbd_server_stop()
read NBD_PID < "$nbd_pid_file"
rm -f "$nbd_pid_file"
if [ -n "$NBD_PID" ]; then
- kill "$NBD_PID"
+ kill -9 "$NBD_PID"
fi
fi
rm -f "$nbd_unix_socket" "$nbd_stderr_fifo"
... but that does not look like the right solution to me. What could prevent
the qemu-nbd from correctly shutting down when it receives a normal SIGTERM
signal?
