I like to use crm history log to get the logs from all the nodes in a single flow, but it depends quite a bit on configuration what gets logged where.. > > What happened: > I tried to configure a simple drbd resource following > http://clusterlabs.org/doc/en-US/Pacemaker/1.1-plugin/html-single/Clusters_from_Scratch/index.html#idm140457860751296 > I used this simple snip from the doc: > configure primitive WebData ocf:linbit:drbd params drbd_resource=wwwdata \ > op monitor interval=60s I'll try to sum up the issues I see, from a glance: * The drbd resource is a multi-state / master-slave resource, which is technically a variant of a clone resource where different clones can either be in a primary or secondary state. To configure it correctly, you'll need to create a master resource as well. Doing this with a single command is unfortunately a bit painful. Either use crm configure edit, or the interactive crm mode (with a verify / commit after creating both the primitive and the master resources). * You'll need to create monitor operations for both the master and slave roles, as you note below, and set explicit timeouts for all operations. * Make sure the wwwdata DRBD resource exists, is accessible from both nodes, and is in a good state to begin with (that is, not split-brained). I would recommend following one of the tutorials provided by Linbit themselves which show how to set this stuff up correctly, since it is quite a bit involved. > Btw: is there a history like in the bash where i see which crm command i > entered at which time ?

We don't have that yet :/ If you're not in interactive mode, your bash history should have the commands though. > no backup - no mercy lol ;) Cheers, Kristoffer -- // Kristoffer Grönlund // kgronl...@suse.com _______________________________________________ Users mailing list: Users@clusterlabs.org http://lists.clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
