Elsukov Hi Andrey, Thank you for the suggestion! With "camcontrol reprobe", GEOM can detect the new disk capacity and the new "free" space! :-) However, there is a strange issue: after I resize "da1" from Hyper-V,=20 if there is a disk read before "camcontrol reprobe da1", gpart couldn't detect the new free space, though it can detect the new disk capacity. I reported a bug for this: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 The workaround is to open da1 for writing. This is weird: how can "read" prevent "camcontrol reprobe da1" from working? It looks there is still a bug somewhere?

Elsukov changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ae@FreeBSD.org --- Comment #3 from Andrey V. Elsukov --- So, disk provider has changed its size, I assume `camcontrol reprobe` has initiated g_disk_resize event. How it should work in my understanding: 1. `camcontrol reprobe` triggers calling of disk_resize() 2. disk_resize() calls g_disk_resize() event 3. GPART class receives resize event, g_part_resize() should be called 4. GPART_MBR's method g_part_mbr_resize() should be called 5. "GEOM_PART: da1 was automatically resized. Use `gpart commit da1` to save changes or `gpart undo da1` to revert them." message should be printed in t= he console. If you don't see the message from p.5 - something doesn't work as expected. You can use the following dtrace command to debug: # kldload dtraceall # dtrace -n 'dtrace -n 'fbt::*disk_resize:entry fbt::g_part_*resize:entry {stack(5);}' --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-geom@freebsd.org Tue Jul 12 12:04:43 2016 Return-Path: Delivered-To: freebsd-geom@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id AF425B93BC1 for ; Tue, 12 Jul 2016 12:04:43 +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 mx1.freebsd.org (Postfix) with ESMTPS id 8D1391D89 for ; Tue, 12 Jul 2016 12:04:43 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u6CC4hXD070212 for ; Tue, 12 Jul 2016 12:04:43 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-geom@FreeBSD.org Subject: [Bug 211028] [GEOM][Hyper-V] gpart can't detect the new free space after the disk capacity changes Date: Tue, 12 Jul 2016 12:04:43 +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: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: ae@FreeBSD.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-bugs@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-geom@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 12 Jul 2016 12:04:43 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 --- Comment #4 from Andrey V.

After the disk capacity change, if I do "camcontrol reprobe da1", gpart can= see both the capacity & free space are updated. After the disk capacity change, if first I open /dev/da1 for reading (e.g. = dd if=3D/dev/da1 of=3Dtmp bs=3D512 count=3D1), da driver notices "Capacity dat= a has changed", and gpart can see the new capacity, but the "free" space shown by gpart is still the old. Next, "camcontrol reprobe da1" can't help and the "free" space shown by gpart is still the old. Next, opening da1 for writing (e.g. dd if=3D/dev/da1 of=3D/dev/da1 bs=3D512 count=3D0) can make gpart sho= w the new "free" space. --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-geom@freebsd.org Wed Jul 13 13:47:29 2016 Return-Path: Delivered-To: freebsd-geom@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 1452CB97CE3 for ; Wed, 13 Jul 2016 13:47:29 +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 mx1.freebsd.org (Postfix) with ESMTPS id 03D7417AD for ; Wed, 13 Jul 2016 13:47:29 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u6DDlSPs082594 for ; Wed, 13 Jul 2016 13:47:28 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-geom@FreeBSD.org Subject: [Bug 211028] [GEOM][Hyper-V] gpart can't detect the new free space after the disk capacity changes Date: Wed, 13 Jul 2016 13:47:28 +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: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: trasz@FreeBSD.org X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-bugs@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-geom@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Wed, 13 Jul 2016 13:47:29 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 --- Comment #9 from Edward Tomasz Napierala --- Hm.

if the disk capacity was changed, in g_disk_access(), we update provide's mediasize ***immediately***: pp->mediasize =3D dp->d_mediasize; Later, in disk_resize(), g_disk_resize() -> g_resize_provider(): because of disk's size =3D=3D pp->mediasize, g_resize_provider() doesn't post the g_resize_provider_event event at all. This is why "camcontrol reprobe da1" can't help. BTW, opening da1 for writing can work because the provider is destroyed and re-created, as you mentioned. I'll be proposing a patch. --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-geom@freebsd.org Fri Jul 15 13:38:48 2016 Return-Path: Delivered-To: freebsd-geom@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id 6DB02B9900A for ; Fri, 15 Jul 2016 13:38:48 +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 mx1.freebsd.org (Postfix) with ESMTPS id 5CE55146B for ; Fri, 15 Jul 2016 13:38:48 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u6FDcmr7070078 for ; Fri, 15 Jul 2016 13:38:48 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-geom@FreeBSD.org Subject: [Bug 211028] [GEOM][Hyper-V] gpart can't detect the new free space after the disk capacity changes Date: Fri, 15 Jul 2016 13:38:48 +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: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: decui@microsoft.com X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-bugs@FreeBSD.org X-Bugzilla-Flags: X-Bugzilla-Changed-Fields: attachments.created 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-geom@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 15 Jul 2016 13:38:48 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 --- Comment #16 from Dexuan Cui --- Created attachment 172554 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D172554&action= =3Dedit The patch can work, but it may be a little ugly... --=20 You are receiving this mail because: You are on the CC list for the bug.= From owner-freebsd-geom@freebsd.org Fri Jul 15 13:44:07 2016 Return-Path: Delivered-To: freebsd-geom@mailman.ysv.freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) by mailman.ysv.freebsd.org (Postfix) with ESMTP id C906CB991DF for ; Fri, 15 Jul 2016 13:44:07 +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 mx1.freebsd.org (Postfix) with ESMTPS id B47461839 for ; Fri, 15 Jul 2016 13:44:07 +0000 (UTC) (envelope-from bugzilla-noreply@freebsd.org) Received: from bugs.freebsd.org ([127.0.1.118]) by kenobi.freebsd.org (8.15.2/8.15.2) with ESMTP id u6FDi793086405 for ; Fri, 15 Jul 2016 13:44:07 GMT (envelope-from bugzilla-noreply@freebsd.org) From: bugzilla-noreply@freebsd.org To: freebsd-geom@FreeBSD.org Subject: [Bug 211028] [GEOM][Hyper-V] gpart can't detect the new free space after the disk capacity changes Date: Fri, 15 Jul 2016 13:44:08 +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: CURRENT X-Bugzilla-Keywords: X-Bugzilla-Severity: Affects Some People X-Bugzilla-Who: decui@microsoft.com X-Bugzilla-Status: New X-Bugzilla-Resolution: X-Bugzilla-Priority: --- X-Bugzilla-Assigned-To: freebsd-bugs@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-geom@freebsd.org X-Mailman-Version: 2.1.22 Precedence: list List-Id: GEOM-specific discussions and implementations List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 15 Jul 2016 13:44:07 -0000 https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D211028 --- Comment #17 from Dexuan Cui --- (In reply to Dexuan Cui from comment #16) Please review the attached patch.
