It would probably screw up on a FreeBSD box too. What's not idle? The file system is mounted, but there are no writes to it during the dump. This and other tests run fine in Freebsd, even without syncs (but of course I'd use sync in a real application). In Linux, even a loop of "while true ; do sync ; sleep 1 ; done" run for 20 minutes makes no difference. There is something very different between Linux and Freebsd here, I just don't know what it is. --Mark To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
