I had the occasion to experience such behavior because of bad optical fibers for instance, generating huge number of network errors. You also have “network failure” messages in your logs and it’s “Waiting for connection”. In your case I’d say the first thing to do is to test this network : Can both nodes ping each other address on this network ? Does an ifconfig of each address report errors ? Etc… I bet when your replication network is up again, your cluster will run fine.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#1F497D'>Pascal.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0cm 0cm 0cm'><p class=MsoNormal align=left style='text-align:left'><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>De :</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> drbd-user-bounces@lists.linbit.com [mailto:drbd-user-bounces@lists.linbit.com] <b>De la part de</b> simon<br><b>Envoyé :</b> samedi 18 août 2012 03:37<br><b>À :</b> drbd-user@lists.linbit.com<br><b>Objet :</b> [DRBD-user] Drbd : PingAsk timeout, about 10 mins.<o:p></o:p></span></p></div></div><p class=MsoNormal align=left style='text-align:left'><o:p> </o:p></p><p class=MsoNormal><span lang=EN-US>Hi all,<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>I used drbd 8.3.7 on HA.
