2795
2796 Friday 14th November 2003
2797 =========================
2798 Some bug fixes & minor enhancements, including:
2799   Backwards compatibility with LVM1 metadata improved.
2800   Missing man pages written.
2801   Tool error codes made more consistent.
2802   vgmknodes written.
2803   O_DIRECT can be turned off if it doesn't work in your kernel.
2804   dumpconfig to display the active configuration file
2805
2806 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2807 If your root filesystem is on an LV, you should run one of those two
2808 commands to fix up the special files in /dev in your real root filesystem
2809 after finishing with your initrd.  Also, remember you can use
2810 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2811 it can't write a lock file to a read-only filesystem.
2812
2813 Wednesday 30th April 2003
2814 =========================
2815 A pvmove implementation is now available for the new metadata format.
2816
2817 When running a command that allocates space (e.g. lvcreate), you can now
2818 restrict not only which disk(s) may be used but also the Physical Extents
2819 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2820
2821
2822 Monday 18th November 2002
2823 ========================
2824
2825 The new format of LVM metadata is ready for you to test!
2826   We expect it to be more efficient and more robust than the original format.
2827   It's more compact and supports transactional changes and replication.
2828   Should things go wrong on a system, it's human-readable (and editable).
2829
2830 Please report any problems you find to the mailing list,
2831 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2832 tested and so quite possibly there'll still be some bugs in it.
2833 Be aware of the disclaimer in the COPYING file.
2834
2835 While testing, we recommend turning logging on in the configuration file
2836 to provide us with diagnostic information:
2837   log {
2838         file="/tmp/lvm2.log"
2839         level=7
2840         activation=1
2841   }
2842
2843 You should schedule regular backups of your configuration file and
2844 metadata backups and archives (normally kept under /etc/lvm).
2845
2846 Please read docs/example.conf and "man lvm.conf" to find out more about
2847 the configuration file.
2848
2849 To convert an existing volume group called vg1 to the new format using
2850 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2851
2852 -M (or --metadatatype in its long form) is a new flag to indicate which
2853 format of metadata the command should use for anything it creates.
2854 Currently, the valid types are "lvm1" and "lvm2" and they can be
2855 abbreviated to "1" and "2" respectively.  The default value for this
2856 flag can be changed in the global section in the config file.
2857
2858 Backwards-compatible support for the original LVM1 metadata format is
2859 maintained, but it can be moved into a shared library or removed
2860 completely with configure's --with-lvm1 option.
2861
2862 Under LVM2, the basic unit of metadata is the volume group.  Different
2863 volume groups can use different formats of metadata - vg1 could use
2864 the original LVM1 format while vg2 used the new format - but you can't
2865 mix formats within a volume group.  So to add a PV to an LVM2-format
2866 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2867
2868 With LVM2-format metadata, lvextend will let you specify striping
2869 parameters.  So an LV could consist of two or more "segments" - the
2870 first segment could have 3 stripes while the second segment has just 2.
2871
2872 LVM2 maintains a backup of the current metadata for each volume group
2873 in /etc/lvm/backup, and puts copies of previous versions in
2874 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2875 create and restore from these files.  If you fully understand what
2876 you're doing, metadata can be changed by editing a copy of a current
2877 backup file and using vgcfgrestore to reload it.
2878
2879 Please read the pvcreate man page for more information on the new
2880 format for metadata.
2881
2882 All tools that can change things have a --test flag which can be used
2883 to check the effect  of a set of cmdline args without really making the
2884 changes.
2885
2886
2887 What's not finished?
2888 ====================
2889 The internal cache.  If you turn on debugging output you'll see lots of
2890 repeated messages, many of which will eventually get optimised out.
2891
2892 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2893 though the real command would work: again, fixing this is waiting for
2894 the work on the cache.
2895
2896 Several of the tools do not yet contain the logic to handle full
2897 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2898 needed to restore metadata if a tool gets interrupted or crashes or
2899 finds something unexpected.  This applies particularly to tools that
2900 work on more than one volume group at once (e.g. vgsplit).
2901
2902 Display output.  Some metadata information cannot yet be displayed.
2903
2904 Recovery tools to salvage "lost" metadata directly from the disks:
2905 but we hope the new format will mean such tools are hardly ever needed!
