Thanks for the detailed explanation. We do have network failover setup, so completely network failure is unlikely. Still, I removed acpid, just in case. Thank you again. On Tue, Mar 25, 2014 at 11:47 AM, Digimer wrote: > On 24/03/14 11:45 PM, Digimer wrote: > >> Consider a fence-loop or an er

Re: [Pacemaker] How to avoid dual fencing ?

Hi 邓尧, This question requires a little longer answer. The delay that Kristoffer talks about is where you set one node to wait a certain number of seconds before fencing the other node. In the opposite direction, the other node does not wait to fence, so in the case where both nodes try to

How much time delay difference is enough ? I'm currently setting the delays at 5s and 15s, dual fencing does disappear, but I'm sure whether the difference is large enough for all situations. On Mon, Mar 24, 2014 at 8:00 PM, Kristoffer Grönlund wrote: > On Mon, 24 Mar 2014 19:41:16 +0800 > 邓尧 w

Hi Andrew, thank you for your answer. I found that blog entry before. I'm pretty sure I'm too stupid to get my information out of that blog entry. You write there: "[...] If the level of detail in the cluster log file is still insufficient, or you simply wish to go blind, you can turn on debuggi

I'm configuring a 2-node cluster on CentOS 6 with corosync + pacemaker + cman. Everything works well except fencing. I'm using IPMI as the fencing device, I know it's not the best fencing device, but this is the only option I have. Manual fencing a node (pcs stonith fence ) works well: peer node g

[Pacemaker] Pacemaker cluster took almost 2 hours to migrate

Hi, We have a 2-node Pacemaker (1.1.7 on Fedora Core 16) cluster that runs a PostgreSQL database on a DRBD drive, Apache, Tomcat and a few custom services. The load is pretty low (a few HTTP clients, a few database clients, infrequent database updates - every hour or so). It worked perfectly f
