2804
2805 Friday 14th November 2003
2806 =========================
2807 Some bug fixes & minor enhancements, including:
2808   Backwards compatibility with LVM1 metadata improved.
2809   Missing man pages written.
2810   Tool error codes made more consistent.
2811   vgmknodes written.
2812   O_DIRECT can be turned off if it doesn't work in your kernel.
2813   dumpconfig to display the active configuration file
2814
2815 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2816 If your root filesystem is on an LV, you should run one of those two
2817 commands to fix up the special files in /dev in your real root filesystem
2818 after finishing with your initrd.  Also, remember you can use
2819 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2820 it can't write a lock file to a read-only filesystem.
2821
2822 Wednesday 30th April 2003
2823 =========================
2824 A pvmove implementation is now available for the new metadata format.
2825
2826 When running a command that allocates space (e.g. lvcreate), you can now
2827 restrict not only which disk(s) may be used but also the Physical Extents
2828 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2829
2830
2831 Monday 18th November 2002
2832 ========================
2833
2834 The new format of LVM metadata is ready for you to test!
2835   We expect it to be more efficient and more robust than the original format.
2836   It's more compact and supports transactional changes and replication.
2837   Should things go wrong on a system, it's human-readable (and editable).
2838
2839 Please report any problems you find to the mailing list,
2840 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2841 tested and so quite possibly there'll still be some bugs in it.
2842 Be aware of the disclaimer in the COPYING file.
2843
2844 While testing, we recommend turning logging on in the configuration file
2845 to provide us with diagnostic information:
2846   log {
2847         file="/tmp/lvm2.log"
2848         level=7
2849         activation=1
2850   }
2851
2852 You should schedule regular backups of your configuration file and
2853 metadata backups and archives (normally kept under /etc/lvm).
2854
2855 Please read docs/example.conf and "man lvm.conf" to find out more about
2856 the configuration file.
2857
2858 To convert an existing volume group called vg1 to the new format using
2859 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2860
2861 -M (or --metadatatype in its long form) is a new flag to indicate which
2862 format of metadata the command should use for anything it creates.
2863 Currently, the valid types are "lvm1" and "lvm2" and they can be
2864 abbreviated to "1" and "2" respectively.  The default value for this
2865 flag can be changed in the global section in the config file.
2866
2867 Backwards-compatible support for the original LVM1 metadata format is
2868 maintained, but it can be moved into a shared library or removed
2869 completely with configure's --with-lvm1 option.
2870
2871 Under LVM2, the basic unit of metadata is the volume group.  Different
2872 volume groups can use different formats of metadata - vg1 could use
2873 the original LVM1 format while vg2 used the new format - but you can't
2874 mix formats within a volume group.  So to add a PV to an LVM2-format
2875 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2876
2877 With LVM2-format metadata, lvextend will let you specify striping
2878 parameters.  So an LV could consist of two or more "segments" - the
2879 first segment could have 3 stripes while the second segment has just 2.
2880
2881 LVM2 maintains a backup of the current metadata for each volume group
2882 in /etc/lvm/backup, and puts copies of previous versions in
2883 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2884 create and restore from these files.  If you fully understand what
2885 you're doing, metadata can be changed by editing a copy of a current
2886 backup file and using vgcfgrestore to reload it.
2887
2888 Please read the pvcreate man page for more information on the new
2889 format for metadata.
2890
2891 All tools that can change things have a --test flag which can be used
2892 to check the effect  of a set of cmdline args without really making the
2893 changes.
2894
2895
2896 What's not finished?
2897 ====================
2898 The internal cache.  If you turn on debugging output you'll see lots of
2899 repeated messages, many of which will eventually get optimised out.
2900
2901 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2902 though the real command would work: again, fixing this is waiting for
2903 the work on the cache.
2904
2905 Several of the tools do not yet contain the logic to handle full
2906 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2907 needed to restore metadata if a tool gets interrupted or crashes or
2908 finds something unexpected.  This applies particularly to tools that
2909 work on more than one volume group at once (e.g. vgsplit).
2910
2911 Display output.  Some metadata information cannot yet be displayed.
2912
2913 Recovery tools to salvage "lost" metadata directly from the disks:
2914 but we hope the new format will mean such tools are hardly ever needed!
