Hi, All
As one node died, another node is to recovery it.
In the function dlm_send_begin_reco_message, if the DLM_BEGIN_RECO_MSG message
is sent to one active node failed, the recovery node will retry to send the
message until it success.
I think in the function dlm_send_finalize_reco_message, we should send the
DLM_FINALIZE_RECO_MSG again to the node when failed.
It should not break out the loop as sending FINALIZE_RECO_MSG to one active
node failed.
It would be good to retry send message to active node until all active nodes
processed the message successfully.
static int dlm_send_finalize_reco_message(struct dlm_ctxt *dlm)
{
stage2:
memset(&fr, 0, sizeof(fr));
fr.node_idx = dlm->node_num;
fr.dead_node = dlm->reco.dead_node;
if (stage == 2)
fr.flags |= DLM_FINALIZE_STAGE2;
while ((nodenum = dlm_node_iter_next(&iter)) >= 0) {
if (nodenum == dlm->node_num)
continue;
+ retry:
ret = o2net_send_message(DLM_FINALIZE_RECO_MSG, dlm->key,
&fr, sizeof(fr), nodenum, &status);
if (ret >= 0)
ret = status;
if (ret < 0) {
mlog(ML_ERROR, "Error %d when sending message %u (key "
"0x%x) to node %u\n", ret, DLM_FINALIZE_RECO_MSG,
dlm->key, nodenum);
if (dlm_is_host_down(ret)) {
/* this has no effect on this recovery
* session, so set the status to zero to
* finish out the last recovery */
mlog(ML_ERROR, "node %u went down after this "
"node finished recovery.\n", nodenum);
ret = 0;
continue;
}
+ msleep(100);
+ goto retry;
- break;
}
}
As break out in the loop, some nodes process the message OK, others may be
failed.
