Re: [Pacemaker] pacemaker fails to start drbd using ocf:linbit:drbd

Hi Bart, . Just some more thoughts: Are you sure that drbd was really stopped? Does this error also happen after a clean restart (without drbd starting at runlevel), i.e. "lsmod | grep drbd" without results? How long does it take if you setup drbd (attach,syncer,connect,primary) manually? Wh

Re: [Pacemaker] pacemaker fails to start drbd using ocf:linbit:drbd

Hi Bart, my guess is that you did forget the start-delay attribute for the monitor operations, that's why you see the time-out error message. Here is an example: op monitor interval="20" role="Slave" timeout="20" start-delay="1m" \ op monitor interval="10" role="Master" timeo

[Pacemaker] resource monitor operations on wrong nodes

Hi, I have a non-symmetric cluster (symmetric-cluster="false") with four nodes. On two nodes I have allowed a resource group: location grpFS-pref1 grpFS 200: wdf-ux-0040 location grpFS-pref2 grpFS 200: wdf-ux-0041 grpFS is configured as: group grpFS resFS resVIP resAPP the other nodes are n

Hi Rasto, I played around with the MC and it is really a promising integrative approach for managing a DRBD and Pacemaker Cluster. For now it is really nice for demonstration purposes like detaching the primary with failover. What I am missing is a resource cleanup (crm resource cleanup ), is t

Hi, first of all: the succesful redesign of the clusterlabs website looks very nice and the splash page is a really good idea! However I found some small teething troubles: * "Explore" tab: - The link "Site updates" is not working yet. - I would also suggest to add a direct link to the wiki (Ho

[Pacemaker] Design: 8 vs 4x2 nodes Cluster

Hi there, I want to realize a rather complex setup, so I have a couple of questions: The cluster (as a shared nothing variant) should provide: * 4 services (=server) depending on each other. * 3 of them can only be realized as active/passive failover, synched with DRBD (M/S) * The servers ru
