2742
2743 Friday 14th November 2003
2744 =========================
2745 Some bug fixes & minor enhancements, including:
2746   Backwards compatibility with LVM1 metadata improved.
2747   Missing man pages written.
2748   Tool error codes made more consistent.
2749   vgmknodes written.
2750   O_DIRECT can be turned off if it doesn't work in your kernel.
2751   dumpconfig to display the active configuration file
2752
2753 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2754 If your root filesystem is on an LV, you should run one of those two
2755 commands to fix up the special files in /dev in your real root filesystem
2756 after finishing with your initrd.  Also, remember you can use
2757 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2758 it can't write a lock file to a read-only filesystem.
2759
2760 Wednesday 30th April 2003
2761 =========================
2762 A pvmove implementation is now available for the new metadata format.
2763
2764 When running a command that allocates space (e.g. lvcreate), you can now
2765 restrict not only which disk(s) may be used but also the Physical Extents
2766 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2767
2768
2769 Monday 18th November 2002
2770 ========================
2771
2772 The new format of LVM metadata is ready for you to test!
2773   We expect it to be more efficient and more robust than the original format.
2774   It's more compact and supports transactional changes and replication.
2775   Should things go wrong on a system, it's human-readable (and editable).
2776
2777 Please report any problems you find to the mailing list,
2778 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2779 tested and so quite possibly there'll still be some bugs in it.
2780 Be aware of the disclaimer in the COPYING file.
2781
2782 While testing, we recommend turning logging on in the configuration file
2783 to provide us with diagnostic information:
2784   log {
2785         file="/tmp/lvm2.log"
2786         level=7
2787         activation=1
2788   }
2789
2790 You should schedule regular backups of your configuration file and
2791 metadata backups and archives (normally kept under /etc/lvm).
2792
2793 Please read docs/example.conf and "man lvm.conf" to find out more about
2794 the configuration file.
2795
2796 To convert an existing volume group called vg1 to the new format using
2797 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2798
2799 -M (or --metadatatype in its long form) is a new flag to indicate which
2800 format of metadata the command should use for anything it creates.
2801 Currently, the valid types are "lvm1" and "lvm2" and they can be
2802 abbreviated to "1" and "2" respectively.  The default value for this
2803 flag can be changed in the global section in the config file.
2804
2805 Backwards-compatible support for the original LVM1 metadata format is
2806 maintained, but it can be moved into a shared library or removed
2807 completely with configure's --with-lvm1 option.
2808
2809 Under LVM2, the basic unit of metadata is the volume group.  Different
2810 volume groups can use different formats of metadata - vg1 could use
2811 the original LVM1 format while vg2 used the new format - but you can't
2812 mix formats within a volume group.  So to add a PV to an LVM2-format
2813 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2814
2815 With LVM2-format metadata, lvextend will let you specify striping
2816 parameters.  So an LV could consist of two or more "segments" - the
2817 first segment could have 3 stripes while the second segment has just 2.
2818
2819 LVM2 maintains a backup of the current metadata for each volume group
2820 in /etc/lvm/backup, and puts copies of previous versions in
2821 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2822 create and restore from these files.  If you fully understand what
2823 you're doing, metadata can be changed by editing a copy of a current
2824 backup file and using vgcfgrestore to reload it.
2825
2826 Please read the pvcreate man page for more information on the new
2827 format for metadata.
2828
2829 All tools that can change things have a --test flag which can be used
2830 to check the effect  of a set of cmdline args without really making the
2831 changes.
2832
2833
2834 What's not finished?
2835 ====================
2836 The internal cache.  If you turn on debugging output you'll see lots of
2837 repeated messages, many of which will eventually get optimised out.
2838
2839 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2840 though the real command would work: again, fixing this is waiting for
2841 the work on the cache.
2842
2843 Several of the tools do not yet contain the logic to handle full
2844 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2845 needed to restore metadata if a tool gets interrupted or crashes or
2846 finds something unexpected.  This applies particularly to tools that
2847 work on more than one volume group at once (e.g. vgsplit).
2848
2849 Display output.  Some metadata information cannot yet be displayed.
2850
2851 Recovery tools to salvage "lost" metadata directly from the disks:
2852 but we hope the new format will mean such tools are hardly ever needed!
