2857
2858 Friday 14th November 2003
2859 =========================
2860 Some bug fixes & minor enhancements, including:
2861   Backwards compatibility with LVM1 metadata improved.
2862   Missing man pages written.
2863   Tool error codes made more consistent.
2864   vgmknodes written.
2865   O_DIRECT can be turned off if it doesn't work in your kernel.
2866   dumpconfig to display the active configuration file
2867
2868 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2869 If your root filesystem is on an LV, you should run one of those two
2870 commands to fix up the special files in /dev in your real root filesystem
2871 after finishing with your initrd.  Also, remember you can use
2872 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2873 it can't write a lock file to a read-only filesystem.
2874
2875 Wednesday 30th April 2003
2876 =========================
2877 A pvmove implementation is now available for the new metadata format.
2878
2879 When running a command that allocates space (e.g. lvcreate), you can now
2880 restrict not only which disk(s) may be used but also the Physical Extents
2881 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2882
2883
2884 Monday 18th November 2002
2885 ========================
2886
2887 The new format of LVM metadata is ready for you to test!
2888   We expect it to be more efficient and more robust than the original format.
2889   It's more compact and supports transactional changes and replication.
2890   Should things go wrong on a system, it's human-readable (and editable).
2891
2892 Please report any problems you find to the mailing list,
2893 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2894 tested and so quite possibly there'll still be some bugs in it.
2895 Be aware of the disclaimer in the COPYING file.
2896
2897 While testing, we recommend turning logging on in the configuration file
2898 to provide us with diagnostic information:
2899   log {
2900         file="/tmp/lvm2.log"
2901         level=7
2902         activation=1
2903   }
2904
2905 You should schedule regular backups of your configuration file and
2906 metadata backups and archives (normally kept under /etc/lvm).
2907
2908 Please read docs/example.conf and "man lvm.conf" to find out more about
2909 the configuration file.
2910
2911 To convert an existing volume group called vg1 to the new format using
2912 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2913
2914 -M (or --metadatatype in its long form) is a new flag to indicate which
2915 format of metadata the command should use for anything it creates.
2916 Currently, the valid types are "lvm1" and "lvm2" and they can be
2917 abbreviated to "1" and "2" respectively.  The default value for this
2918 flag can be changed in the global section in the config file.
2919
2920 Backwards-compatible support for the original LVM1 metadata format is
2921 maintained, but it can be moved into a shared library or removed
2922 completely with configure's --with-lvm1 option.
2923
2924 Under LVM2, the basic unit of metadata is the volume group.  Different
2925 volume groups can use different formats of metadata - vg1 could use
2926 the original LVM1 format while vg2 used the new format - but you can't
2927 mix formats within a volume group.  So to add a PV to an LVM2-format
2928 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2929
2930 With LVM2-format metadata, lvextend will let you specify striping
2931 parameters.  So an LV could consist of two or more "segments" - the
2932 first segment could have 3 stripes while the second segment has just 2.
2933
2934 LVM2 maintains a backup of the current metadata for each volume group
2935 in /etc/lvm/backup, and puts copies of previous versions in
2936 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2937 create and restore from these files.  If you fully understand what
2938 you're doing, metadata can be changed by editing a copy of a current
2939 backup file and using vgcfgrestore to reload it.
2940
2941 Please read the pvcreate man page for more information on the new
2942 format for metadata.
2943
2944 All tools that can change things have a --test flag which can be used
2945 to check the effect  of a set of cmdline args without really making the
2946 changes.
2947
2948
2949 What's not finished?
2950 ====================
2951 The internal cache.  If you turn on debugging output you'll see lots of
2952 repeated messages, many of which will eventually get optimised out.
2953
2954 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2955 though the real command would work: again, fixing this is waiting for
2956 the work on the cache.
2957
2958 Several of the tools do not yet contain the logic to handle full
2959 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2960 needed to restore metadata if a tool gets interrupted or crashes or
2961 finds something unexpected.  This applies particularly to tools that
2962 work on more than one volume group at once (e.g. vgsplit).
2963
2964 Display output.  Some metadata information cannot yet be displayed.
2965
2966 Recovery tools to salvage "lost" metadata directly from the disks:
2967 but we hope the new format will mean such tools are hardly ever needed!
