2877
2878 Friday 14th November 2003
2879 =========================
2880 Some bug fixes & minor enhancements, including:
2881   Backwards compatibility with LVM1 metadata improved.
2882   Missing man pages written.
2883   Tool error codes made more consistent.
2884   vgmknodes written.
2885   O_DIRECT can be turned off if it doesn't work in your kernel.
2886   dumpconfig to display the active configuration file
2887
2888 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2889 If your root filesystem is on an LV, you should run one of those two
2890 commands to fix up the special files in /dev in your real root filesystem
2891 after finishing with your initrd.  Also, remember you can use
2892 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2893 it can't write a lock file to a read-only filesystem.
2894
2895 Wednesday 30th April 2003
2896 =========================
2897 A pvmove implementation is now available for the new metadata format.
2898
2899 When running a command that allocates space (e.g. lvcreate), you can now
2900 restrict not only which disk(s) may be used but also the Physical Extents
2901 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2902
2903
2904 Monday 18th November 2002
2905 ========================
2906
2907 The new format of LVM metadata is ready for you to test!
2908   We expect it to be more efficient and more robust than the original format.
2909   It's more compact and supports transactional changes and replication.
2910   Should things go wrong on a system, it's human-readable (and editable).
2911
2912 Please report any problems you find to the mailing list,
2913 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2914 tested and so quite possibly there'll still be some bugs in it.
2915 Be aware of the disclaimer in the COPYING file.
2916
2917 While testing, we recommend turning logging on in the configuration file
2918 to provide us with diagnostic information:
2919   log {
2920         file="/tmp/lvm2.log"
2921         level=7
2922         activation=1
2923   }
2924
2925 You should schedule regular backups of your configuration file and
2926 metadata backups and archives (normally kept under /etc/lvm).
2927
2928 Please read docs/example.conf and "man lvm.conf" to find out more about
2929 the configuration file.
2930
2931 To convert an existing volume group called vg1 to the new format using
2932 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2933
2934 -M (or --metadatatype in its long form) is a new flag to indicate which
2935 format of metadata the command should use for anything it creates.
2936 Currently, the valid types are "lvm1" and "lvm2" and they can be
2937 abbreviated to "1" and "2" respectively.  The default value for this
2938 flag can be changed in the global section in the config file.
2939
2940 Backwards-compatible support for the original LVM1 metadata format is
2941 maintained, but it can be moved into a shared library or removed
2942 completely with configure's --with-lvm1 option.
2943
2944 Under LVM2, the basic unit of metadata is the volume group.  Different
2945 volume groups can use different formats of metadata - vg1 could use
2946 the original LVM1 format while vg2 used the new format - but you can't
2947 mix formats within a volume group.  So to add a PV to an LVM2-format
2948 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2949
2950 With LVM2-format metadata, lvextend will let you specify striping
2951 parameters.  So an LV could consist of two or more "segments" - the
2952 first segment could have 3 stripes while the second segment has just 2.
2953
2954 LVM2 maintains a backup of the current metadata for each volume group
2955 in /etc/lvm/backup, and puts copies of previous versions in
2956 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2957 create and restore from these files.  If you fully understand what
2958 you're doing, metadata can be changed by editing a copy of a current
2959 backup file and using vgcfgrestore to reload it.
2960
2961 Please read the pvcreate man page for more information on the new
2962 format for metadata.
2963
2964 All tools that can change things have a --test flag which can be used
2965 to check the effect  of a set of cmdline args without really making the
2966 changes.
2967
2968
2969 What's not finished?
2970 ====================
2971 The internal cache.  If you turn on debugging output you'll see lots of
2972 repeated messages, many of which will eventually get optimised out.
2973
2974 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2975 though the real command would work: again, fixing this is waiting for
2976 the work on the cache.
2977
2978 Several of the tools do not yet contain the logic to handle full
2979 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2980 needed to restore metadata if a tool gets interrupted or crashes or
2981 finds something unexpected.  This applies particularly to tools that
2982 work on more than one volume group at once (e.g. vgsplit).
2983
2984 Display output.  Some metadata information cannot yet be displayed.
2985
2986 Recovery tools to salvage "lost" metadata directly from the disks:
2987 but we hope the new format will mean such tools are hardly ever needed!
