Device removal code uses zio_vdev_child_io() with ZIO_TYPE_NULL parent, that never happened before. It confused FreeBSD-specific TRIM code, which does not use VDEV_IO_DONE for logical ZIO_TYPE_FREE ZIOs. As result of that stage being skipped device removal ZIOs leaked references and memory that supposed to be freed by VDEV_IO_DONE, making it stuck. It is a quick patch rather then a nice fix, but hopefully we'll be able to drop it all together when alternative TRIM implementation finally get landed.

I just received a reply to a query on the nfsv4@ietf.org mailing list and t= he set of encryption types supported by Linux is the same as above except they do no support Arcfour_56. However, they are planning on deleting support for all encryption types except for the AES ones. As such, it sounds like you may need to configure Kerberos to only use thos= e to ensure interoperability in the future.

only ZIO_TYPE_READ and some ZIO_TYPE_WRITE requests to removed (indirect) vdevs, while on FreeBSD there is also ZIO_TYPE_FREE (TRIM). ZIO_TYPE_FREE requests do not have the data buffers, so don't need the pointer adjustment.

Device removal code uses zio_vdev_child_io() with ZIO_TYPE_NULL parent, that never happened before. It confused FreeBSD-specific TRIM code, which does not use VDEV_IO_DONE for logical ZIO_TYPE_FREE ZIOs. As result of that stage being skipped device removal ZIOs leaked references and memory that supposed to be freed by VDEV_IO_DONE, making it stuck. It is a quick patch rather then a nice fix, but hopefully we'll be able to drop it all together when alternative TRIM implementation finally get landed.

I looked at taskq_wait() in FreeBSD vs. illumos. On FreeBSD it will only wait for currently queued tasks to finish; anything enqueued after the drain starts may not be finished by the time we return. On illumos it looks like taskq_wait() will wait until the queue is completely empty. So, if the asy= nc evictions queue some additional evictions, on FreeBSD we won't recursively wait, and the taskq_wait() will return early. I can't tell if ZFS is making this assumption though. --=20 You are receiving this mail because: You are the assignee for the bug.= From owner-freebsd-fs@freebsd.org Sat Oct 20 08:01:43 2018 Return-Path: Delivered-To: freebsd-fs@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 78201FFCE30 for ; Sat, 20 Oct 2018 08:01:43 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mailman.ysv.freebsd.org (mailman.ysv.freebsd.org [IPv6:2001:1900:2254:206a::50:5]) by mx1.freebsd.org (Postfix) with ESMTP id 14BFA8336D for ; Sat, 20 Oct 2018 08:01:43 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: by mailman.ysv.freebsd.org (Postfix) id CE3E1FFCE2E; Sat, 20 Oct 2018 08:01:42 +0000 (UTC) Delivered-To: fs@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id BD2FEFFCE2D for ; Sat, 20 Oct 2018 08:01:42 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.ysv.freebsd.org (mxrelay.ysv.freebsd.org [IPv6:2001:1900:2254:206a::19:3]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client CN "mxrelay.ysv.freebsd.org", Issuer "Let's Encrypt Authority X3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 60BE083364 for ; Sat, 20 Oct 2018 08:01:42 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2001:1900:2254:206a::16:76]) (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits)) (Client did not present a certificate) by mxrelay.ysv.freebsd.org (Postfix) with ESMTPS id A837C151D3 for ; Sat, 20 Oct 2018 08:01:41 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id w9K81fAA033593 for ; Sat, 20 Oct 2018 08:01:41 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id w9K81fxm033589 for fs@FreeBSD.org; Sat, 20 Oct 2018 08:01:41 GMT (envelope-from bugzilla-noreply@freebsd.org) X-Authentication-Warning: kenobi.freebsd.org: www set sender to bugzilla-noreply@freebsd.org using -f From: bugzilla-noreply@freebsd.org To: fs@FreeBSD.org Subject: [Bug 227784] zfs: Fatal trap 9: general protection fault while in kernel mode on shutdown Date: Sat, 20 Oct 2018 08:01:40 +0000 X-Bugzilla-Reason: AssignedTo X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: CURRENT X-Bugzilla-Keywords: panic, regression X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: avg@FreeBSD.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: fs@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: Message-ID: In-Reply-To: References: Content-Type: text/plain; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: https://bugs.freebsd.org/bugzilla/ Auto-Submitted: auto-generated MIME-Version: 1.0 X-BeenThere: freebsd-fs@freebsd.org X-Mailman-Version: 2.1.29 Precedence: list List-Id: Filesystems List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 20 Oct 2018 08:01:43 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D227784 --- Comment #16 from Andriy Gapon --- (In reply to Mark Johnston from comment #15) $ORIGIN is a special hidden dataset that has no data and has a single snaps= hot $ORIGIN@$ORIGIN.

And indeed: just slap a gmultipath(8)= in there and the bandwidth issue is gone! This hack is quite a mess but so far it's stable, fast and it works astonishingly great. I'm actually planning using this in production. --=20 You are receiving this mail because: You are the assignee for the bug.=
