Message-ID: <388@sequent.UUCP> Date: Sat, 11-Feb-84 12:52:04 EST Article-I.D.: sequent.388 Posted: Sat Feb 11 12:52:04 1984 Date-Received: Sat, 18-Feb-84 04:15:21 EST References: <200@iwu1c.UUCP> <1171@cincy.UUCP> Organization: Sequent Computer Systems, Portland Lines: 14 The best bet is to insure a quiet system. Most implementations of update() ("sync" internally) don't touch busy nodes... So, you might miss some unless the system is quiet. Best to unmount all mounted things first, too (this *will* insure all IO done (depending on drivers, and particular UNIX in question)). Since it's very hard to tell just when inode "x" is in use from *outside* the kernel, incantations of various sorts might be appropriate :-) You're not paranoid if they *are* out to get you... -- Bob Beck Sequent Computer Systems ...ogcvax!sequent!rbk (503)627-9809
