'cman_tool status' will tell you about quorum. But, if only one node in a two node cluster is up, and you don't have two_node=1, then we already know that your cluster didn't have quorum. group_tool will tell you the recovery status of fencing, dlm and gfs. > >Either, possibly; you'd have to try it out.

Despite being used for similar things, they are completely different commands with completely different implementations. Since flock() is a far simpler command, its implementation is far simpler, faster, and works much better in general.
