failures, which would cause cascade failures in the rest of the test run: link/15.t, open/19.t, mkdir/11.t, mkfifo/11.t, symlink/11.t Fail quickly in all of the testcases if mdconfig, mount, umount, etc fails to avoid issues similar to this in the future Submitted by: Casey Peel <cpeel@isilon.com> MFC after: 2 weeks X-MFC with: r272057 Sponsored by: EMC / Isilon Storage Division
