2867
2868 Friday 14th November 2003
2869 =========================
2870 Some bug fixes & minor enhancements, including:
2871   Backwards compatibility with LVM1 metadata improved.
2872   Missing man pages written.
2873   Tool error codes made more consistent.
2874   vgmknodes written.
2875   O_DIRECT can be turned off if it doesn't work in your kernel.
2876   dumpconfig to display the active configuration file
2877
2878 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2879 If your root filesystem is on an LV, you should run one of those two
2880 commands to fix up the special files in /dev in your real root filesystem
2881 after finishing with your initrd.  Also, remember you can use
2882 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2883 it can't write a lock file to a read-only filesystem.
2884
2885 Wednesday 30th April 2003
2886 =========================
2887 A pvmove implementation is now available for the new metadata format.
2888
2889 When running a command that allocates space (e.g. lvcreate), you can now
2890 restrict not only which disk(s) may be used but also the Physical Extents
2891 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2892
2893
2894 Monday 18th November 2002
2895 ========================
2896
2897 The new format of LVM metadata is ready for you to test!
2898   We expect it to be more efficient and more robust than the original format.
2899   It's more compact and supports transactional changes and replication.
2900   Should things go wrong on a system, it's human-readable (and editable).
2901
2902 Please report any problems you find to the mailing list,
2903 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2904 tested and so quite possibly there'll still be some bugs in it.
2905 Be aware of the disclaimer in the COPYING file.
2906
2907 While testing, we recommend turning logging on in the configuration file
2908 to provide us with diagnostic information:
2909   log {
2910         file="/tmp/lvm2.log"
2911         level=7
2912         activation=1
2913   }
2914
2915 You should schedule regular backups of your configuration file and
2916 metadata backups and archives (normally kept under /etc/lvm).
2917
2918 Please read docs/example.conf and "man lvm.conf" to find out more about
2919 the configuration file.
2920
2921 To convert an existing volume group called vg1 to the new format using
2922 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2923
2924 -M (or --metadatatype in its long form) is a new flag to indicate which
2925 format of metadata the command should use for anything it creates.
2926 Currently, the valid types are "lvm1" and "lvm2" and they can be
2927 abbreviated to "1" and "2" respectively.  The default value for this
2928 flag can be changed in the global section in the config file.
2929
2930 Backwards-compatible support for the original LVM1 metadata format is
2931 maintained, but it can be moved into a shared library or removed
2932 completely with configure's --with-lvm1 option.
2933
2934 Under LVM2, the basic unit of metadata is the volume group.  Different
2935 volume groups can use different formats of metadata - vg1 could use
2936 the original LVM1 format while vg2 used the new format - but you can't
2937 mix formats within a volume group.  So to add a PV to an LVM2-format
2938 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2939
2940 With LVM2-format metadata, lvextend will let you specify striping
2941 parameters.  So an LV could consist of two or more "segments" - the
2942 first segment could have 3 stripes while the second segment has just 2.
2943
2944 LVM2 maintains a backup of the current metadata for each volume group
2945 in /etc/lvm/backup, and puts copies of previous versions in
2946 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2947 create and restore from these files.  If you fully understand what
2948 you're doing, metadata can be changed by editing a copy of a current
2949 backup file and using vgcfgrestore to reload it.
2950
2951 Please read the pvcreate man page for more information on the new
2952 format for metadata.
2953
2954 All tools that can change things have a --test flag which can be used
2955 to check the effect  of a set of cmdline args without really making the
2956 changes.
2957
2958
2959 What's not finished?
2960 ====================
2961 The internal cache.  If you turn on debugging output you'll see lots of
2962 repeated messages, many of which will eventually get optimised out.
2963
2964 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2965 though the real command would work: again, fixing this is waiting for
2966 the work on the cache.
2967
2968 Several of the tools do not yet contain the logic to handle full
2969 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2970 needed to restore metadata if a tool gets interrupted or crashes or
2971 finds something unexpected.  This applies particularly to tools that
2972 work on more than one volume group at once (e.g. vgsplit).
2973
2974 Display output.  Some metadata information cannot yet be displayed.
2975
2976 Recovery tools to salvage "lost" metadata directly from the disks:
2977 but we hope the new format will mean such tools are hardly ever needed!
