2869
2870 Friday 14th November 2003
2871 =========================
2872 Some bug fixes & minor enhancements, including:
2873   Backwards compatibility with LVM1 metadata improved.
2874   Missing man pages written.
2875   Tool error codes made more consistent.
2876   vgmknodes written.
2877   O_DIRECT can be turned off if it doesn't work in your kernel.
2878   dumpconfig to display the active configuration file
2879
2880 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2881 If your root filesystem is on an LV, you should run one of those two
2882 commands to fix up the special files in /dev in your real root filesystem
2883 after finishing with your initrd.  Also, remember you can use
2884 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2885 it can't write a lock file to a read-only filesystem.
2886
2887 Wednesday 30th April 2003
2888 =========================
2889 A pvmove implementation is now available for the new metadata format.
2890
2891 When running a command that allocates space (e.g. lvcreate), you can now
2892 restrict not only which disk(s) may be used but also the Physical Extents
2893 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2894
2895
2896 Monday 18th November 2002
2897 ========================
2898
2899 The new format of LVM metadata is ready for you to test!
2900   We expect it to be more efficient and more robust than the original format.
2901   It's more compact and supports transactional changes and replication.
2902   Should things go wrong on a system, it's human-readable (and editable).
2903
2904 Please report any problems you find to the mailing list,
2905 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2906 tested and so quite possibly there'll still be some bugs in it.
2907 Be aware of the disclaimer in the COPYING file.
2908
2909 While testing, we recommend turning logging on in the configuration file
2910 to provide us with diagnostic information:
2911   log {
2912         file="/tmp/lvm2.log"
2913         level=7
2914         activation=1
2915   }
2916
2917 You should schedule regular backups of your configuration file and
2918 metadata backups and archives (normally kept under /etc/lvm).
2919
2920 Please read docs/example.conf and "man lvm.conf" to find out more about
2921 the configuration file.
2922
2923 To convert an existing volume group called vg1 to the new format using
2924 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2925
2926 -M (or --metadatatype in its long form) is a new flag to indicate which
2927 format of metadata the command should use for anything it creates.
2928 Currently, the valid types are "lvm1" and "lvm2" and they can be
2929 abbreviated to "1" and "2" respectively.  The default value for this
2930 flag can be changed in the global section in the config file.
2931
2932 Backwards-compatible support for the original LVM1 metadata format is
2933 maintained, but it can be moved into a shared library or removed
2934 completely with configure's --with-lvm1 option.
2935
2936 Under LVM2, the basic unit of metadata is the volume group.  Different
2937 volume groups can use different formats of metadata - vg1 could use
2938 the original LVM1 format while vg2 used the new format - but you can't
2939 mix formats within a volume group.  So to add a PV to an LVM2-format
2940 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2941
2942 With LVM2-format metadata, lvextend will let you specify striping
2943 parameters.  So an LV could consist of two or more "segments" - the
2944 first segment could have 3 stripes while the second segment has just 2.
2945
2946 LVM2 maintains a backup of the current metadata for each volume group
2947 in /etc/lvm/backup, and puts copies of previous versions in
2948 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2949 create and restore from these files.  If you fully understand what
2950 you're doing, metadata can be changed by editing a copy of a current
2951 backup file and using vgcfgrestore to reload it.
2952
2953 Please read the pvcreate man page for more information on the new
2954 format for metadata.
2955
2956 All tools that can change things have a --test flag which can be used
2957 to check the effect  of a set of cmdline args without really making the
2958 changes.
2959
2960
2961 What's not finished?
2962 ====================
2963 The internal cache.  If you turn on debugging output you'll see lots of
2964 repeated messages, many of which will eventually get optimised out.
2965
2966 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2967 though the real command would work: again, fixing this is waiting for
2968 the work on the cache.
2969
2970 Several of the tools do not yet contain the logic to handle full
2971 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2972 needed to restore metadata if a tool gets interrupted or crashes or
2973 finds something unexpected.  This applies particularly to tools that
2974 work on more than one volume group at once (e.g. vgsplit).
2975
2976 Display output.  Some metadata information cannot yet be displayed.
2977
2978 Recovery tools to salvage "lost" metadata directly from the disks:
2979 but we hope the new format will mean such tools are hardly ever needed!
