Please don't consider using it +or making it available to others without reading the following. + + +By far the most significant change in this release related to the +management of reshaping arrays. This code has been substantially +re-written so that it can work with 'externally managed metadata' - +Intel's IMSM in particular. We now support level migration and +OnLine Capacity Expansion on these arrays. + +However, while the code largely works it has not been tested +exhaustively so there are likely to be problems. As the reshape code +for native metadata arrays was changed as part of this rewrite these +problems could also result in regressions for reshape of native +metadata. + +It is partly to encourage greater testing that this release is being +made. Any reports of problem - particular reproducible recipes for +triggering the problems - will be gratefully received. + +It is hopped that a "3.2.1" release will be available in early March +which will be a bugfix release over this and can be considered +suitable for general use. + +Other changes of note: + + - Policy framework. + Various policy statements can be made in the mdadm.conf to guide + the behaviour of mdadm, particular with regards to how new devices + are treated by "mdadm -I". + Depending on the 'action' associated with a device (identified by + its 'path') such need devices can be automatically re-added to and + existing array that they previously fell out off, or automatically + added as a spare if they appear to contain no data. + + - mdadm now has a limited understanding of partition tables. This + allows the policy framework to make decisions about partitioned + devices as well. + + - --incremental --remove can be told what --path the device was on, + and this info will be recorded so that another device appearing at + the same physical location can be preferentially added to the same + array (provides the spare-same-slot action policy applied to the + path). + + - A new flags "--invalid-backup" flag is available in --assemble + mode. This can be used to re-assemble an array which was stopping + in the middle of a reshape, and for which the 'backup file' is no + longer available or is corrupted. The array may have some + corruption in it at the point where reshape was up to, but at least + the rest of the array will become available. + + + - Various internal restructuring - more is needed. + + +Any feed back and bug reports are always welcomed at: + linux-raid@vger.kernel.org + +And please: don't use this in production - particularly not the +--grow functionality. + +NeilBrown 1st February 2011 + + @@ -24,7 +24,7 @@ #include "mdadm.h" -char Version[] = Name " - v3.2-devel - 23rd November 2010\n"; +char Version[] = Name " - v3.2 DEVELOPER_ONLY - 1st February 2011 (USE WITH CARE)\n"; /* * File: ReadMe.c @@ -8,6 +8,7 @@ ANNOUNCE-3.1.1 ANNOUNCE-3.1.2 ANNOUNCE-3.1.3 ANNOUNCE-3.1.4 +ANNOUNCE-3.2 Assemble.c bitmap.c bitmap.h @@ -22,6 +23,7 @@ Detail.c dlink.c dlink.h Examine.c +external-reshape-design.txt .gitignore Grow.c Incremental.c @@ -50,6 +52,7 @@ mdassemble.8 mdassemble.c mdmon.8 mdmon.c +mdmon-design.txt mdmon.h mdopen.c md_p.h @@ -62,8 +65,10 @@ monitor.c Monitor.c msg.c msg.h +part.h platform-intel.c platform-intel.h +policy.c probe_roms.c probe_roms.h pwgr.c @@ -78,7 +83,9 @@ sha1.h super0.c super1.c super-ddf.c +super-gpt.c super-intel.c +super-mbr.c swap_super.c sysfs.c test @@ -135,12 +142,48 @@ tests/08imsm-overlap tests/09imsm-assemble tests/09imsm-create-fail-rebuild tests/10ddf-create +tests/11spare-migration +tests/12imsm-r0_2d-grow-r0_3d +tests/12imsm-r0_2d-grow-r0_4d +tests/12imsm-r0_2d-grow-r0_5d +tests/12imsm-r0_3d-grow-r0_4d +tests/12imsm-r5_3d-grow-r5_4d +tests/12imsm-r5_3d-grow-r5_5d +tests/13imsm-r0_r0_2d-grow-r0_r0_4d +tests/13imsm-r0_r0_2d-grow-r0_r0_5d +tests/13imsm-r0_r0_3d-grow-r0_r0_4d +tests/13imsm-r0_r5_3d-grow-r0_r5_4d +tests/13imsm-r0_r5_3d-grow-r0_r5_5d +tests/13imsm-r5_r0_3d-grow-r5_r0_4d +tests/13imsm-r5_r0_3d-grow-r5_r0_5d +tests/14imsm-r0_3d_no_spares-migrate-r5_3d +tests/14imsm-r0_3d-r5_3d-migrate-r5_4d-r5_4d +tests/14imsm-r0_r0_2d-takeover-r10_4d +tests/14imsm-r10_4d-grow-r10_5d +tests/14imsm-r10_r5_4d-takeover-r0_2d +tests/14imsm-r1_2d-grow-r1_3d +tests/14imsm-r1_2d-takeover-r0_2d +tests/14imsm-r5_3d-grow-r5_5d-no-spares +tests/14imsm-r5_3d-migrate-r4_3d +tests/15imsm-r0_3d_64k-migrate-r0_3d_256k +tests/15imsm-r5_3d_4k-migrate-r5_3d_256k +tests/15imsm-r5_3d_64k-migrate-r5_3d_256k +tests/15imsm-r5_6d_4k-migrate-r5_6d_256k +tests/15imsm-r5_r0_3d_64k-migrate-r5_r0_3d_256k +tests/16imsm-r0_3d-migrate-r5_4d +tests/16imsm-r0_5d-migrate-r5_6d +tests/16imsm-r5_3d-migrate-r0_3d +tests/16imsm-r5_5d-migrate-r0_5d +tests/18imsm-1d-takeover-r0_1d +tests/18imsm-1d-takeover-r1_2d +tests/18imsm-r0_2d-takeover-r10_4d +tests/18imsm-r10_4d-takeover-r0_2d tests/check -tests/env-08imsm-overlap -tests/env-09imsm-assemble -tests/env-09imsm-create-fail-rebuild +tests/env-imsm-template +tests/imsm-grow-template tests/testdev tests/ToTest +tests/utils TODO udev-md-raid.rules util.c @@ -5,7 +5,7 @@ .\" the Free Software Foundation; either version 2 of the License, or .\" (at your option) any later version. .\" See file COPYING in distribution for details. -.TH MDADM 8 "" v3.1.4 +.TH MDADM 8 "" v3.2 .SH NAME mdadm \- manage MD devices .I aka @@ -1,6 +1,6 @@ Summary: mdadm is used for controlling Linux md devices (aka RAID arrays) Name: mdadm -Version: 3.1.4 +Version: 3.2 Release: 1 Source: http://www.kernel.org/pub/linux/utils/raid/mdadm/mdadm-%{version}.tgz URL: http://neil.brown.name/blog/mdadm diff --git a/mdassemble.8 b/mdassemble.8 index 986432cc..5c442ee3 100644 --- a/mdassemble.8 +++ b/mdassemble.8 @@ -1,5 +1,5 @@ .\" -*- nroff -*- -.TH MDASSEMBLE 8 "" v3.1.4 +.TH MDASSEMBLE 8 "" v3.2 .SH NAME mdassemble \- assemble MD devices .I aka @@ -1,5 +1,5 @@ .\" See file COPYING in distribution for details. -.TH MDMON 8 "" v3.1.4 +.TH MDMON 8 "" v3.2-devel .SH NAME mdmon \- monitor MD external metadata arrays |
