2839
2840 Friday 14th November 2003
2841 =========================
2842 Some bug fixes & minor enhancements, including:
2843   Backwards compatibility with LVM1 metadata improved.
2844   Missing man pages written.
2845   Tool error codes made more consistent.
2846   vgmknodes written.
2847   O_DIRECT can be turned off if it doesn't work in your kernel.
2848   dumpconfig to display the active configuration file
2849
2850 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2851 If your root filesystem is on an LV, you should run one of those two
2852 commands to fix up the special files in /dev in your real root filesystem
2853 after finishing with your initrd.  Also, remember you can use
2854 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2855 it can't write a lock file to a read-only filesystem.
2856
2857 Wednesday 30th April 2003
2858 =========================
2859 A pvmove implementation is now available for the new metadata format.
2860
2861 When running a command that allocates space (e.g. lvcreate), you can now
2862 restrict not only which disk(s) may be used but also the Physical Extents
2863 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2864
2865
2866 Monday 18th November 2002
2867 ========================
2868
2869 The new format of LVM metadata is ready for you to test!
2870   We expect it to be more efficient and more robust than the original format.
2871   It's more compact and supports transactional changes and replication.
2872   Should things go wrong on a system, it's human-readable (and editable).
2873
2874 Please report any problems you find to the mailing list,
2875 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2876 tested and so quite possibly there'll still be some bugs in it.
2877 Be aware of the disclaimer in the COPYING file.
2878
2879 While testing, we recommend turning logging on in the configuration file
2880 to provide us with diagnostic information:
2881   log {
2882         file="/tmp/lvm2.log"
2883         level=7
2884         activation=1
2885   }
2886
2887 You should schedule regular backups of your configuration file and
2888 metadata backups and archives (normally kept under /etc/lvm).
2889
2890 Please read docs/example.conf and "man lvm.conf" to find out more about
2891 the configuration file.
2892
2893 To convert an existing volume group called vg1 to the new format using
2894 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2895
2896 -M (or --metadatatype in its long form) is a new flag to indicate which
2897 format of metadata the command should use for anything it creates.
2898 Currently, the valid types are "lvm1" and "lvm2" and they can be
2899 abbreviated to "1" and "2" respectively.  The default value for this
2900 flag can be changed in the global section in the config file.
2901
2902 Backwards-compatible support for the original LVM1 metadata format is
2903 maintained, but it can be moved into a shared library or removed
2904 completely with configure's --with-lvm1 option.
2905
2906 Under LVM2, the basic unit of metadata is the volume group.  Different
2907 volume groups can use different formats of metadata - vg1 could use
2908 the original LVM1 format while vg2 used the new format - but you can't
2909 mix formats within a volume group.  So to add a PV to an LVM2-format
2910 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2911
2912 With LVM2-format metadata, lvextend will let you specify striping
2913 parameters.  So an LV could consist of two or more "segments" - the
2914 first segment could have 3 stripes while the second segment has just 2.
2915
2916 LVM2 maintains a backup of the current metadata for each volume group
2917 in /etc/lvm/backup, and puts copies of previous versions in
2918 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2919 create and restore from these files.  If you fully understand what
2920 you're doing, metadata can be changed by editing a copy of a current
2921 backup file and using vgcfgrestore to reload it.
2922
2923 Please read the pvcreate man page for more information on the new
2924 format for metadata.
2925
2926 All tools that can change things have a --test flag which can be used
2927 to check the effect  of a set of cmdline args without really making the
2928 changes.
2929
2930
2931 What's not finished?
2932 ====================
2933 The internal cache.  If you turn on debugging output you'll see lots of
2934 repeated messages, many of which will eventually get optimised out.
2935
2936 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2937 though the real command would work: again, fixing this is waiting for
2938 the work on the cache.
2939
2940 Several of the tools do not yet contain the logic to handle full
2941 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2942 needed to restore metadata if a tool gets interrupted or crashes or
2943 finds something unexpected.  This applies particularly to tools that
2944 work on more than one volume group at once (e.g. vgsplit).
2945
2946 Display output.  Some metadata information cannot yet be displayed.
2947
2948 Recovery tools to salvage "lost" metadata directly from the disks:
2949 but we hope the new format will mean such tools are hardly ever needed!
