New Revision: 317309
URL: https://svnweb.freebsd.org/changeset/base/317309

Log:
  gctl_test.t: improve error reporting with mdcfg and mount directives
  
  If the commands had failed previously, it would press on and result in a
  series of cascading failures. Fail early and continue on to the next case
  instead of executing additional commands after a previously failed series
  of steps.
  
  MFC after:      5 weeks
