I now believe the fix w= orks on your case as well. * Fix Status I am now checking the ARC eviction and pruning triggered by the vm_lowmem kernel event. There was a case where the system stalled with pagedaemon{um= a} running at the WCPU of ~0.3% in the late stage of poudriere-bulk(8). I sus= pect that a pagedaemon thread put itself to the arc_evict_waiters list in arc_wait_for_eviction(), called by arc_lowmem(), to handle the vm_lowmem ke= rnel event. In such the case, the ARC pruning has to work more eagerly so that = the pagedaemon thread does not block forever. The issue above has been confirmed experimentally by checking for the non-e= mpty arc_evict_waiters list in {arc,zfs}_prune_task(). Also, arc_lowmem() has t= he lines for such the case. > static void > arc_lowmem(void *arg __unused, int howto __unused) > { > (snip) > /* > * It is unsafe to block here in arbitrary threads, because we can come > * here from ARC itself and may hold ARC locks and thus risk a deadlock > * with ARC reclaim thread. > */ > if (curproc =3D=3D pageproc) > arc_wait_for_eviction(to_free, B_FALSE); > } After the current test, I will see if this issue can be worked out somehow. --=20 You are receiving this mail because: You are the assignee for the bug.= From nobody Fri Feb 2 07:54:33 2024 X-Original-To: fs@mlmmj.nyi.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2610:1c1:1:606c::19:1]) by mlmmj.nyi.freebsd.org (Postfix) with ESMTP id 4TR7Ms2mNpz58Ctr for ; Fri, 2 Feb 2024 07:54:33 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from mxrelay.nyi.freebsd.org (mxrelay.nyi.freebsd.org [IPv6:2610:1c1:1:606c::19:3]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256 client-signature RSA-PSS (4096 bits) client-digest SHA256) (Client CN "mxrelay.nyi.freebsd.org", Issuer "R3" (verified OK)) by mx1.freebsd.org (Postfix) with ESMTPS id 4TR7Ms0hvMz4fCN for ; Fri, 2 Feb 2024 07:54:33 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) ARC-Message-Signature: i=1; a=rsa-sha256; c=relaxed/relaxed; d=freebsd.org; s=dkim; t=1706860473; h=from:from:reply-to:subject:subject:date:date:message-id:message-id: to:to:cc:mime-version:mime-version:content-type:content-type: content-transfer-encoding:content-transfer-encoding: in-reply-to:in-reply-to:references:references; bh=tt9d0ZMUHerEHxCockFGOchd1SAQCZ4sDyk0qT0jf0A=; b=wg8ElkiAxw8laAxZ/IQFc2rlkfP+afvoXCgTF3cBjHTklmwRzO00jDDS4byd1s33rGWeQg fsHDiWYM4HSNgzr2oRIp/tORfwsAKfGioNf1jIxCYgsd1JijJpQgx5OkYctEXDU0vfqvBB stIs54Jb9V+VC6p/UeMEGJrHlKEDQGTGYEbtuDUu/0oTNAmwEdrAmanvOesfr9kcOK2UEb M7WFWrYnsmGjGcRS67VIZNP8mJcnm7irz+w6m0tNUSxardLhDD1Cc+wq6UYJM6Z2ngrMV6 GZBfDYwhVbdkzZJ2KpyOAIyjzCttO7045RAcLHXvuTagk00mV7942HD6C2XrYQ== ARC-Authentication-Results: i=1; mx1.freebsd.org; none ARC-Seal: i=1; s=dkim; d=freebsd.org; t=1706860473; a=rsa-sha256; cv=none; b=HMg9ts3v9Lnoo5n3w5dtb0YGZBmhcscJHzVKDQHGl3nFR5y+OiHXplqFYQo0iRMfScl1rV ChausOuqDQI6UXWtUMP9WOKzI1QDIYRTjebi1eLMdavMZCXSppOOVh2R6ji+CulASaXAAH 62t7ifV1tFh7lMut0dKSD8Om9HOIHZN8T9VMjVI1Xk6HWgadiiPDtkUscJXEwepVvbGKn6 NlbGWAy0VqZwsVrGCTg+xeQtVUwq9TDglVB04UNlHNE1XXI4H8pwBkEyfVJ/ysf1Ac5OAU wCwLXqImPN15ibzBZrPLHQu6kMF+VNhGtz72uG81FBcSGqEpAyntqwrxng9BDg== Received: from kenobi.freebsd.org (kenobi.freebsd.org [IPv6:2610:1c1:1:606c::50:1d]) (using TLSv1.3 with cipher TLS_AES_256_GCM_SHA384 (256/256 bits) key-exchange X25519 server-signature RSA-PSS (4096 bits) server-digest SHA256) (Client did not present a certificate) by mxrelay.nyi.freebsd.org (Postfix) with ESMTPS id 4TR7Mr6vGCzMRc for ; Fri, 2 Feb 2024 07:54:32 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from kenobi.freebsd.org ([127.0.1.5]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id 4127sW9Y031216 for ; Fri, 2 Feb 2024 07:54:32 GMT (envelope-from bugzilla-noreply@freebsd.org) Received: (from www@localhost) by kenobi.freebsd.org (8.15.2/8.15.2/Submit) id 4127sWrt031214 for fs@FreeBSD.org; Fri, 2 Feb 2024 07:54:32 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 273772] zpool nested in ZVOL becomes inaccessible when zfsd(8) is running on the host Date: Fri, 02 Feb 2024 07:54:33 +0000 X-Bugzilla-Reason: CC X-Bugzilla-Type: changed X-Bugzilla-Watch-Reason: None X-Bugzilla-Product: Base System X-Bugzilla-Component: kern X-Bugzilla-Version: 14.0-STABLE X-Bugzilla-Keywords: needs-qa, regression X-Bugzilla-Severity: Affects Only Me X-Bugzilla-Who: zarychtam@plan-b.pwste.edu.pl X-Bugzilla-Status: Open X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: virtualization@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 List-Id: Filesystems List-Archive: https://lists.freebsd.org/archives/freebsd-fs List-Help: List-Post: List-Subscribe: List-Unsubscribe: Sender: owner-freebsd-fs@freebsd.org MIME-Version: 1.0 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D273772 --- Comment #11 from Marek Zarychta --- Now both: bhyve host and guest are running FreeBSD stable/14. ZFS pools on = host and guest were upgraded. The report is still valid and the issue is persist= ent. Maybe the transition to mirror (the guest is nested on a ZVOL of pool with= a top-level-vdev that had previously been removed) has something to do with it (see bug 273663). The guest is using host's ZVOL zroot/ZVOL/virtbsd as vtbd= 0. This is how ZFS looks on the host:=20 # zpool status zroot pool: zroot state: ONLINE scan: scrub repaired 0B in 00:11:06 with 0 errors on Fri Jan 26 03:21:55 = 2024 scan warning: skipped blocks that
