2848
2849 Friday 14th November 2003
2850 =========================
2851 Some bug fixes & minor enhancements, including:
2852   Backwards compatibility with LVM1 metadata improved.
2853   Missing man pages written.
2854   Tool error codes made more consistent.
2855   vgmknodes written.
2856   O_DIRECT can be turned off if it doesn't work in your kernel.
2857   dumpconfig to display the active configuration file
2858
2859 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2860 If your root filesystem is on an LV, you should run one of those two
2861 commands to fix up the special files in /dev in your real root filesystem
2862 after finishing with your initrd.  Also, remember you can use
2863 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2864 it can't write a lock file to a read-only filesystem.
2865
2866 Wednesday 30th April 2003
2867 =========================
2868 A pvmove implementation is now available for the new metadata format.
2869
2870 When running a command that allocates space (e.g. lvcreate), you can now
2871 restrict not only which disk(s) may be used but also the Physical Extents
2872 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2873
2874
2875 Monday 18th November 2002
2876 ========================
2877
2878 The new format of LVM metadata is ready for you to test!
2879   We expect it to be more efficient and more robust than the original format.
2880   It's more compact and supports transactional changes and replication.
2881   Should things go wrong on a system, it's human-readable (and editable).
2882
2883 Please report any problems you find to the mailing list,
2884 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2885 tested and so quite possibly there'll still be some bugs in it.
2886 Be aware of the disclaimer in the COPYING file.
2887
2888 While testing, we recommend turning logging on in the configuration file
2889 to provide us with diagnostic information:
2890   log {
2891         file="/tmp/lvm2.log"
2892         level=7
2893         activation=1
2894   }
2895
2896 You should schedule regular backups of your configuration file and
2897 metadata backups and archives (normally kept under /etc/lvm).
2898
2899 Please read docs/example.conf and "man lvm.conf" to find out more about
2900 the configuration file.
2901
2902 To convert an existing volume group called vg1 to the new format using
2903 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2904
2905 -M (or --metadatatype in its long form) is a new flag to indicate which
2906 format of metadata the command should use for anything it creates.
2907 Currently, the valid types are "lvm1" and "lvm2" and they can be
2908 abbreviated to "1" and "2" respectively.  The default value for this
2909 flag can be changed in the global section in the config file.
2910
2911 Backwards-compatible support for the original LVM1 metadata format is
2912 maintained, but it can be moved into a shared library or removed
2913 completely with configure's --with-lvm1 option.
2914
2915 Under LVM2, the basic unit of metadata is the volume group.  Different
2916 volume groups can use different formats of metadata - vg1 could use
2917 the original LVM1 format while vg2 used the new format - but you can't
2918 mix formats within a volume group.  So to add a PV to an LVM2-format
2919 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2920
2921 With LVM2-format metadata, lvextend will let you specify striping
2922 parameters.  So an LV could consist of two or more "segments" - the
2923 first segment could have 3 stripes while the second segment has just 2.
2924
2925 LVM2 maintains a backup of the current metadata for each volume group
2926 in /etc/lvm/backup, and puts copies of previous versions in
2927 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2928 create and restore from these files.  If you fully understand what
2929 you're doing, metadata can be changed by editing a copy of a current
2930 backup file and using vgcfgrestore to reload it.
2931
2932 Please read the pvcreate man page for more information on the new
2933 format for metadata.
2934
2935 All tools that can change things have a --test flag which can be used
2936 to check the effect  of a set of cmdline args without really making the
2937 changes.
2938
2939
2940 What's not finished?
2941 ====================
2942 The internal cache.  If you turn on debugging output you'll see lots of
2943 repeated messages, many of which will eventually get optimised out.
2944
2945 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2946 though the real command would work: again, fixing this is waiting for
2947 the work on the cache.
2948
2949 Several of the tools do not yet contain the logic to handle full
2950 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2951 needed to restore metadata if a tool gets interrupted or crashes or
2952 finds something unexpected.  This applies particularly to tools that
2953 work on more than one volume group at once (e.g. vgsplit).
2954
2955 Display output.  Some metadata information cannot yet be displayed.
2956
2957 Recovery tools to salvage "lost" metadata directly from the disks:
2958 but we hope the new format will mean such tools are hardly ever needed!
