presumably the socket failure injectino is what triggred the issue.. and why it usually works.
Updated by Nathan Cutler over 7 years ago
The offending code in qa/workunits/cephtool/test.sh is:
function test_mon_ping()
{
ceph ping mon.a
ceph ping mon.b
expect_false ceph ping mon.foo
ceph ping mon.\*
}
I guess it should run the "ceph ping" commands, say, five times and sleep 5 seconds between each try?
Answer:
(11:28:12 PM) sage: smithfarm: hmm, i think the ping socket error should trigger a reconnect attempt and be masked at that level
(11:28:49 PM) sage: proably need to reproduce it with a client log debug objecter = 20 and debug ms = 20 log with the socket error injection turned up

That's with "ms inject socket failures: 500" which is unchanged. What's a reasonable higher value to try - 1000? 5000?
Updated by Chang Liu about 7 years ago
Its value should be lower so that fault is easier to reproduce. Now, ping socket error will reconnect automatically as:
./bin/ceph ping mon.a
