I think it's this, my error messages are exactly the same: https://github.com/ClusterLabs/libqb/issues/338 Reproducible: Always Steps to Reproduce: 1. emerge corosync pacemaker 2. create minimal cluster, no resources required 3. start services Actual Results: May 01 14:27:07 m1 cib[171751]: error: Error in connection setup (/dev/shm/qb-171751-171752-10-SEeELe): Unknown error -1 (-1) May 01 14:27:07 m1 stonith-ng[171752]: error: couldn't open file /dev/shm/qb-: No such file or directory (2) May 01 14:27:07 m1 stonith-ng[171752]: error: couldn't open file /var/lib/run/: No such file or directory (2) May 01 14:27:07 m1 stonith-ng[171752]: error: couldn't open file for mmap: No such file or directory (2) Services eventually fail. Expected Results: Services should run without errors and function normally. This is fixed in libqb-1.9.1, which can be created by copying libqb-1.9.0.ebuild exactly and installing. I can't see anything in the ebuild suggest it isn't this simple, but I didn't write the original.
