[Pacemaker] 2-node cluster with shared storage: what is current solution

[Саша Александров]

Hi!

I removed all clustr-related staff and installed from
http://download.opensuse.org/repositories/network:/ha-clustering:/Stable/CentOS_CentOS-6/x86_64/
However, stonith-ng uses fence_* agents here...  So I cannot put into crmsh

primitive stonith_sbd stonith:external/sbd

:-(
