I'm running into an issues with the pgsql resource agent running on CentOS7.
The issue is when the pgsql resource agent attempts a call to runasowner it
uses a su as user postgres in a call to ocf_run, this is causing what appears
to be a new session on CentOS7.
We've narrowed it down to the ocf_run method in ocf-shellfuncs in executing the
command:
output=`"$@" 2>&1`
Snippet of /var/log/messages:

Software versions:
pacemaker 1.1.10
resource-agents 3.9.5
corosync 2.3.3-2
Has anyone else experienced this issue or know of what might be going wrong to
cause new sessions to be created?
Thanks,
Brendan
