2859
2860 Friday 14th November 2003
2861 =========================
2862 Some bug fixes & minor enhancements, including:
2863   Backwards compatibility with LVM1 metadata improved.
2864   Missing man pages written.
2865   Tool error codes made more consistent.
2866   vgmknodes written.
2867   O_DIRECT can be turned off if it doesn't work in your kernel.
2868   dumpconfig to display the active configuration file
2869
2870 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2871 If your root filesystem is on an LV, you should run one of those two
2872 commands to fix up the special files in /dev in your real root filesystem
2873 after finishing with your initrd.  Also, remember you can use
2874 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2875 it can't write a lock file to a read-only filesystem.
2876
2877 Wednesday 30th April 2003
2878 =========================
2879 A pvmove implementation is now available for the new metadata format.
2880
2881 When running a command that allocates space (e.g. lvcreate), you can now
2882 restrict not only which disk(s) may be used but also the Physical Extents
2883 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2884
2885
2886 Monday 18th November 2002
2887 ========================
2888
2889 The new format of LVM metadata is ready for you to test!
2890   We expect it to be more efficient and more robust than the original format.
2891   It's more compact and supports transactional changes and replication.
2892   Should things go wrong on a system, it's human-readable (and editable).
2893
2894 Please report any problems you find to the mailing list,
2895 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2896 tested and so quite possibly there'll still be some bugs in it.
2897 Be aware of the disclaimer in the COPYING file.
2898
2899 While testing, we recommend turning logging on in the configuration file
2900 to provide us with diagnostic information:
2901   log {
2902         file="/tmp/lvm2.log"
2903         level=7
2904         activation=1
2905   }
2906
2907 You should schedule regular backups of your configuration file and
2908 metadata backups and archives (normally kept under /etc/lvm).
2909
2910 Please read docs/example.conf and "man lvm.conf" to find out more about
2911 the configuration file.
2912
2913 To convert an existing volume group called vg1 to the new format using
2914 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2915
2916 -M (or --metadatatype in its long form) is a new flag to indicate which
2917 format of metadata the command should use for anything it creates.
2918 Currently, the valid types are "lvm1" and "lvm2" and they can be
2919 abbreviated to "1" and "2" respectively.  The default value for this
2920 flag can be changed in the global section in the config file.
2921
2922 Backwards-compatible support for the original LVM1 metadata format is
2923 maintained, but it can be moved into a shared library or removed
2924 completely with configure's --with-lvm1 option.
2925
2926 Under LVM2, the basic unit of metadata is the volume group.  Different
2927 volume groups can use different formats of metadata - vg1 could use
2928 the original LVM1 format while vg2 used the new format - but you can't
2929 mix formats within a volume group.  So to add a PV to an LVM2-format
2930 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2931
2932 With LVM2-format metadata, lvextend will let you specify striping
2933 parameters.  So an LV could consist of two or more "segments" - the
2934 first segment could have 3 stripes while the second segment has just 2.
2935
2936 LVM2 maintains a backup of the current metadata for each volume group
2937 in /etc/lvm/backup, and puts copies of previous versions in
2938 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2939 create and restore from these files.  If you fully understand what
2940 you're doing, metadata can be changed by editing a copy of a current
2941 backup file and using vgcfgrestore to reload it.
2942
2943 Please read the pvcreate man page for more information on the new
2944 format for metadata.
2945
2946 All tools that can change things have a --test flag which can be used
2947 to check the effect  of a set of cmdline args without really making the
2948 changes.
2949
2950
2951 What's not finished?
2952 ====================
2953 The internal cache.  If you turn on debugging output you'll see lots of
2954 repeated messages, many of which will eventually get optimised out.
2955
2956 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2957 though the real command would work: again, fixing this is waiting for
2958 the work on the cache.
2959
2960 Several of the tools do not yet contain the logic to handle full
2961 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2962 needed to restore metadata if a tool gets interrupted or crashes or
2963 finds something unexpected.  This applies particularly to tools that
2964 work on more than one volume group at once (e.g. vgsplit).
2965
2966 Display output.  Some metadata information cannot yet be displayed.
2967
2968 Recovery tools to salvage "lost" metadata directly from the disks:
2969 but we hope the new format will mean such tools are hardly ever needed!
