2772 Friday 14th November 2003
2773 =========================
2774 Some bug fixes & minor enhancements, including:
2775   Backwards compatibility with LVM1 metadata improved.
2776   Missing man pages written.
2777   Tool error codes made more consistent.
2778   vgmknodes written.
2779   O_DIRECT can be turned off if it doesn't work in your kernel.
2780   dumpconfig to display the active configuration file
2781
2782 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2783 If your root filesystem is on an LV, you should run one of those two
2784 commands to fix up the special files in /dev in your real root filesystem
2785 after finishing with your initrd.  Also, remember you can use
2786 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2787 it can't write a lock file to a read-only filesystem.
2788
2789 Wednesday 30th April 2003
2790 =========================
2791 A pvmove implementation is now available for the new metadata format.
2792
2793 When running a command that allocates space (e.g. lvcreate), you can now
2794 restrict not only which disk(s) may be used but also the Physical Extents
2795 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2796
2797
2798 Monday 18th November 2002
2799 ========================
2800
2801 The new format of LVM metadata is ready for you to test!
2802   We expect it to be more efficient and more robust than the original format.
2803   It's more compact and supports transactional changes and replication.
2804   Should things go wrong on a system, it's human-readable (and editable).
2805
2806 Please report any problems you find to the mailing list,
2807 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2808 tested and so quite possibly there'll still be some bugs in it.
2809 Be aware of the disclaimer in the COPYING file.
2810
2811 While testing, we recommend turning logging on in the configuration file
2812 to provide us with diagnostic information:
2813   log {
2814         file="/tmp/lvm2.log"
2815         level=7
2816         activation=1
2817   }
2818
2819 You should schedule regular backups of your configuration file and
2820 metadata backups and archives (normally kept under /etc/lvm).
2821
2822 Please read docs/example.conf and "man lvm.conf" to find out more about
2823 the configuration file.
2824
2825 To convert an existing volume group called vg1 to the new format using
2826 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2827
2828 -M (or --metadatatype in its long form) is a new flag to indicate which
2829 format of metadata the command should use for anything it creates.
2830 Currently, the valid types are "lvm1" and "lvm2" and they can be
2831 abbreviated to "1" and "2" respectively.  The default value for this
2832 flag can be changed in the global section in the config file.
2833
2834 Backwards-compatible support for the original LVM1 metadata format is
2835 maintained, but it can be moved into a shared library or removed
2836 completely with configure's --with-lvm1 option.
2837
2838 Under LVM2, the basic unit of metadata is the volume group.  Different
2839 volume groups can use different formats of metadata - vg1 could use
2840 the original LVM1 format while vg2 used the new format - but you can't
2841 mix formats within a volume group.  So to add a PV to an LVM2-format
2842 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2843
2844 With LVM2-format metadata, lvextend will let you specify striping
2845 parameters.  So an LV could consist of two or more "segments" - the
2846 first segment could have 3 stripes while the second segment has just 2.
2847
2848 LVM2 maintains a backup of the current metadata for each volume group
2849 in /etc/lvm/backup, and puts copies of previous versions in
2850 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2851 create and restore from these files.  If you fully understand what
2852 you're doing, metadata can be changed by editing a copy of a current
2853 backup file and using vgcfgrestore to reload it.
2854
2855 Please read the pvcreate man page for more information on the new
2856 format for metadata.
2857
2858 All tools that can change things have a --test flag which can be used
2859 to check the effect  of a set of cmdline args without really making the
2860 changes.
2861
2862
2863 What's not finished?
2864 ====================
2865 The internal cache.  If you turn on debugging output you'll see lots of
2866 repeated messages, many of which will eventually get optimised out.
2867
2868 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2869 though the real command would work: again, fixing this is waiting for
2870 the work on the cache.
2871
2872 Several of the tools do not yet contain the logic to handle full
2873 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2874 needed to restore metadata if a tool gets interrupted or crashes or
2875 finds something unexpected.  This applies particularly to tools that
2876 work on more than one volume group at once (e.g. vgsplit).
2877
2878 Display output.  Some metadata information cannot yet be displayed.
2879
2880 Recovery tools to salvage "lost" metadata directly from the disks:
2881 but we hope the new format will mean such tools are hardly ever needed!
