I'm taking a crack at it again. So far, it seems to be a combination of softupdates+vinum+raid5 that triggers the bug, whatever it is. If I turn off softupdates the raid5 volume seems happy, with and without async. It seems likely to be some odd interaction between the raid5 code and softupdates, since the simpler mirror/striping seems to work fine with it. Ring any bells for anyone? -- Parag Patel To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
