fcntl(F_SETLK) returning ENOSYS
...where we see fnctl(F_SETLK) return ENOSYS. This happens after a node has failed/been fenced and recovered. It affects only individual mounts, not the whole system. The only code path that I can see so far that could lead to ENOSYS being returned here is from within dlm_controld:process_plocks() if disable_plocks == 1.
