2801
2802 Friday 14th November 2003
2803 =========================
2804 Some bug fixes & minor enhancements, including:
2805   Backwards compatibility with LVM1 metadata improved.
2806   Missing man pages written.
2807   Tool error codes made more consistent.
2808   vgmknodes written.
2809   O_DIRECT can be turned off if it doesn't work in your kernel.
2810   dumpconfig to display the active configuration file
2811
2812 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2813 If your root filesystem is on an LV, you should run one of those two
2814 commands to fix up the special files in /dev in your real root filesystem
2815 after finishing with your initrd.  Also, remember you can use
2816 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2817 it can't write a lock file to a read-only filesystem.
2818
2819 Wednesday 30th April 2003
2820 =========================
2821 A pvmove implementation is now available for the new metadata format.
2822
2823 When running a command that allocates space (e.g. lvcreate), you can now
2824 restrict not only which disk(s) may be used but also the Physical Extents
2825 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2826
2827
2828 Monday 18th November 2002
2829 ========================
2830
2831 The new format of LVM metadata is ready for you to test!
2832   We expect it to be more efficient and more robust than the original format.
2833   It's more compact and supports transactional changes and replication.
2834   Should things go wrong on a system, it's human-readable (and editable).
2835
2836 Please report any problems you find to the mailing list,
2837 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2838 tested and so quite possibly there'll still be some bugs in it.
2839 Be aware of the disclaimer in the COPYING file.
2840
2841 While testing, we recommend turning logging on in the configuration file
2842 to provide us with diagnostic information:
2843   log {
2844         file="/tmp/lvm2.log"
2845         level=7
2846         activation=1
2847   }
2848
2849 You should schedule regular backups of your configuration file and
2850 metadata backups and archives (normally kept under /etc/lvm).
2851
2852 Please read docs/example.conf and "man lvm.conf" to find out more about
2853 the configuration file.
2854
2855 To convert an existing volume group called vg1 to the new format using
2856 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2857
2858 -M (or --metadatatype in its long form) is a new flag to indicate which
2859 format of metadata the command should use for anything it creates.
2860 Currently, the valid types are "lvm1" and "lvm2" and they can be
2861 abbreviated to "1" and "2" respectively.  The default value for this
2862 flag can be changed in the global section in the config file.
2863
2864 Backwards-compatible support for the original LVM1 metadata format is
2865 maintained, but it can be moved into a shared library or removed
2866 completely with configure's --with-lvm1 option.
2867
2868 Under LVM2, the basic unit of metadata is the volume group.  Different
2869 volume groups can use different formats of metadata - vg1 could use
2870 the original LVM1 format while vg2 used the new format - but you can't
2871 mix formats within a volume group.  So to add a PV to an LVM2-format
2872 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2873
2874 With LVM2-format metadata, lvextend will let you specify striping
2875 parameters.  So an LV could consist of two or more "segments" - the
2876 first segment could have 3 stripes while the second segment has just 2.
2877
2878 LVM2 maintains a backup of the current metadata for each volume group
2879 in /etc/lvm/backup, and puts copies of previous versions in
2880 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2881 create and restore from these files.  If you fully understand what
2882 you're doing, metadata can be changed by editing a copy of a current
2883 backup file and using vgcfgrestore to reload it.
2884
2885 Please read the pvcreate man page for more information on the new
2886 format for metadata.
2887
2888 All tools that can change things have a --test flag which can be used
2889 to check the effect  of a set of cmdline args without really making the
2890 changes.
2891
2892
2893 What's not finished?
2894 ====================
2895 The internal cache.  If you turn on debugging output you'll see lots of
2896 repeated messages, many of which will eventually get optimised out.
2897
2898 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2899 though the real command would work: again, fixing this is waiting for
2900 the work on the cache.
2901
2902 Several of the tools do not yet contain the logic to handle full
2903 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2904 needed to restore metadata if a tool gets interrupted or crashes or
2905 finds something unexpected.  This applies particularly to tools that
2906 work on more than one volume group at once (e.g. vgsplit).
2907
2908 Display output.  Some metadata information cannot yet be displayed.
2909
2910 Recovery tools to salvage "lost" metadata directly from the disks:
2911 but we hope the new format will mean such tools are hardly ever needed!
