[ClusterLabs] Setup problem: couldn't find command: tcm_node

[Jason A Ramsey]

Hmm. lio-utils is replaced with targetcli in rhel7. Is there any way to make pacemaker use targetcli? I’m starting to wonder if it’s even possible to make an HA iSCSI Target with RedHat...

The error message that I’m seeing leads me to believe that I’m missing something on the systems (“tcm_node”). Here are my setup commands leading up to seeing this error message:

    tcm_node is part of lio-utils. I am not familiar with RedHat packages,
    but I presume that searching for "lio" should reveal something.
