Subject: [PATCH 221/221] protocol/client: propagte GF_EVENT_CHILD_PING only
|
|
for connections to brick
|
|
|
|
Two reasons:
|
|
* ping responses from glusterd may not be relevant for Halo
|
|
replication. Instead, it might be interested in only knowing whether
|
|
the brick itself is responsive.
|
|
* When a brick is killed, propagating GF_EVENT_CHILD_PING of ping
|
|
response from glusterd results in GF_EVENT_DISCONNECT spuriously
|
|
propagated to parent xlators. These DISCONNECT events are from the
|
|
connections client establishes with glusterd as part of its
|
|
reconnect logic. Without GF_EVENT_CHILD_PING, the last event
|
|
propagated to parent xlators would be the first DISCONNECT event
|
|
from brick and hence subsequent DISCONNECTS to glusterd are not
|
|
propagated as protocol/client prevents same event being propagated
|
|
to parent xlators consecutively. propagating GF_EVENT_CHILD_PING for
|
|
ping responses from glusterd would change the last_sent_event to
|
|
GF_EVENT_CHILD_PING and hence protocol/client cannot prevent
|
|
subsequent DISCONNECT events
