Description Trefex 2015-08-17 09:17:47 UTC
Description of problem:

After adding a node to a 2-node setup, I performed a `gluster volume rebalance live fix-layout start`, and after some time, the fix-layout fails with the following error.

How reproducible:

We tried 3-4 times and it happened everytime.

Additional info:

Steps to reproduce:

1. Add a new node to a 2-node setup (already full with files)
2. Start a `gluster volume rebalance live fix-layout start`
3. Wait 20k-40k seconds
4. rebalance failed

we block reading from socket till event-handler completes. This might cause spurious disconnects due to ping-timer expiry if handlers take more time. In this bug, the load seems to be from readdirp. I just looked at readdirp reply path. It involves looping over dentry list from various translators:

1. protocol/client construct dentry list and hence it traverses the list.
2. afr does a loop over dentries
3. dht does a loop over dentries
4. syncop_readdirp_cbk (rebalance process use syncops) copies each dentry and constructs a new list.

I am suspecting whether such heavy processing in handler might've prevented the client from reading the ping response from socket (if ping response was queued behind readdirp response), resulting in timeout of ping-timer.

One solution is that it would be better if we start reading from socket once we read a complete rpc msg. We need not wait till rpc-program/rpc-clnt above transport to process the reply.

<rpc_clnt_ping_timer_expired>

                gettimeofday (&current, NULL);
                if (((current.tv_sec - conn->last_received.tv_sec) <
                     conn->ping_timeout)
                    || ((current.tv_sec - conn->last_sent.tv_sec) <
                        conn->ping_timeout)) {
                        transport_activity = 1;
		}

                if (transport_activity) {
                        gf_log (trans->name, GF_LOG_TRACE,
                                "ping timer expired but transport activity "
                                "detected - not bailing transport");

                        if (__rpc_clnt_rearm_ping_timer (rpc,
                                         rpc_clnt_ping_timer_expired) == -1) {
                                gf_log (trans->name, GF_LOG_WARNING,
					"unable to setup ping timer");
                        }

                } else {
                        conn->ping_started = 0;
                        disconnect = 1;
                }

</rpc_clnt_ping_timer_expired>

As can be seen above, ping_timer_expired takes "transport_activity" into account before actually disconnecting (Its not just ping response we are looking at). Hence RCA in previous comment is most likely wrong.
