Spectra Logic and iXSystems both experienced many problems with this. The worst is a deadlock that can be triggered simply by pulling a drive from a redundant pool when there exists a zvol anywhere in the system (see https://reviews.freebsd.org/D4998 for a quick way to reproduce). Fixing it correctly would likely require far more time than I have available. I just want the bugs to go away. See that same code review for a change to make the feature optional. -Alan _______________________________________________ svn-src-all@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-all To unsubscribe, send any mail to "svn-src-all-unsubscr...@freebsd.org"
