2789
2790 Friday 14th November 2003
2791 =========================
2792 Some bug fixes & minor enhancements, including:
2793   Backwards compatibility with LVM1 metadata improved.
2794   Missing man pages written.
2795   Tool error codes made more consistent.
2796   vgmknodes written.
2797   O_DIRECT can be turned off if it doesn't work in your kernel.
2798   dumpconfig to display the active configuration file
2799
2800 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2801 If your root filesystem is on an LV, you should run one of those two
2802 commands to fix up the special files in /dev in your real root filesystem
2803 after finishing with your initrd.  Also, remember you can use
2804 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2805 it can't write a lock file to a read-only filesystem.
2806
2807 Wednesday 30th April 2003
2808 =========================
2809 A pvmove implementation is now available for the new metadata format.
2810
2811 When running a command that allocates space (e.g. lvcreate), you can now
2812 restrict not only which disk(s) may be used but also the Physical Extents
2813 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2814
2815
2816 Monday 18th November 2002
2817 ========================
2818
2819 The new format of LVM metadata is ready for you to test!
2820   We expect it to be more efficient and more robust than the original format.
2821   It's more compact and supports transactional changes and replication.
2822   Should things go wrong on a system, it's human-readable (and editable).
2823
2824 Please report any problems you find to the mailing list,
2825 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2826 tested and so quite possibly there'll still be some bugs in it.
2827 Be aware of the disclaimer in the COPYING file.
2828
2829 While testing, we recommend turning logging on in the configuration file
2830 to provide us with diagnostic information:
2831   log {
2832         file="/tmp/lvm2.log"
2833         level=7
2834         activation=1
2835   }
2836
2837 You should schedule regular backups of your configuration file and
2838 metadata backups and archives (normally kept under /etc/lvm).
2839
2840 Please read docs/example.conf and "man lvm.conf" to find out more about
2841 the configuration file.
2842
2843 To convert an existing volume group called vg1 to the new format using
2844 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2845
2846 -M (or --metadatatype in its long form) is a new flag to indicate which
2847 format of metadata the command should use for anything it creates.
2848 Currently, the valid types are "lvm1" and "lvm2" and they can be
2849 abbreviated to "1" and "2" respectively.  The default value for this
2850 flag can be changed in the global section in the config file.
2851
2852 Backwards-compatible support for the original LVM1 metadata format is
2853 maintained, but it can be moved into a shared library or removed
2854 completely with configure's --with-lvm1 option.
2855
2856 Under LVM2, the basic unit of metadata is the volume group.  Different
2857 volume groups can use different formats of metadata - vg1 could use
2858 the original LVM1 format while vg2 used the new format - but you can't
2859 mix formats within a volume group.  So to add a PV to an LVM2-format
2860 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2861
2862 With LVM2-format metadata, lvextend will let you specify striping
2863 parameters.  So an LV could consist of two or more "segments" - the
2864 first segment could have 3 stripes while the second segment has just 2.
2865
2866 LVM2 maintains a backup of the current metadata for each volume group
2867 in /etc/lvm/backup, and puts copies of previous versions in
2868 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2869 create and restore from these files.  If you fully understand what
2870 you're doing, metadata can be changed by editing a copy of a current
2871 backup file and using vgcfgrestore to reload it.
2872
2873 Please read the pvcreate man page for more information on the new
2874 format for metadata.
2875
2876 All tools that can change things have a --test flag which can be used
2877 to check the effect  of a set of cmdline args without really making the
2878 changes.
2879
2880
2881 What's not finished?
2882 ====================
2883 The internal cache.  If you turn on debugging output you'll see lots of
2884 repeated messages, many of which will eventually get optimised out.
2885
2886 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2887 though the real command would work: again, fixing this is waiting for
2888 the work on the cache.
2889
2890 Several of the tools do not yet contain the logic to handle full
2891 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2892 needed to restore metadata if a tool gets interrupted or crashes or
2893 finds something unexpected.  This applies particularly to tools that
2894 work on more than one volume group at once (e.g. vgsplit).
2895
2896 Display output.  Some metadata information cannot yet be displayed.
2897
2898 Recovery tools to salvage "lost" metadata directly from the disks:
2899 but we hope the new format will mean such tools are hardly ever needed!
