tests: Fix spurious failures in stats-dump.t test
The test fails to grep and find queue_size, in a brick stats dump, having succesfully found aggr.* values in the same. The troubleshot is that, the writer thread in io-stats, that dumps this in a particular interval, truncates the file just before the grep attempts to read the contents, and hence the failure. The fix is to stop the dumper thread, and then wait for a couple of seconds and then check the output, so that the thread writer does not interfere with the test. Fixes: bz#1615582 Change-Id: I29f95488a2ad693abe1dd525b1d87a9d1eee29a2 Signed-off-by: ShyamsundarR <>
