2783
2784 Friday 14th November 2003
2785 =========================
2786 Some bug fixes & minor enhancements, including:
2787   Backwards compatibility with LVM1 metadata improved.
2788   Missing man pages written.
2789   Tool error codes made more consistent.
2790   vgmknodes written.
2791   O_DIRECT can be turned off if it doesn't work in your kernel.
2792   dumpconfig to display the active configuration file
2793
2794 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2795 If your root filesystem is on an LV, you should run one of those two
2796 commands to fix up the special files in /dev in your real root filesystem
2797 after finishing with your initrd.  Also, remember you can use
2798 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2799 it can't write a lock file to a read-only filesystem.
2800
2801 Wednesday 30th April 2003
2802 =========================
2803 A pvmove implementation is now available for the new metadata format.
2804
2805 When running a command that allocates space (e.g. lvcreate), you can now
2806 restrict not only which disk(s) may be used but also the Physical Extents
2807 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2808
2809
2810 Monday 18th November 2002
2811 ========================
2812
2813 The new format of LVM metadata is ready for you to test!
2814   We expect it to be more efficient and more robust than the original format.
2815   It's more compact and supports transactional changes and replication.
2816   Should things go wrong on a system, it's human-readable (and editable).
2817
2818 Please report any problems you find to the mailing list,
2819 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2820 tested and so quite possibly there'll still be some bugs in it.
2821 Be aware of the disclaimer in the COPYING file.
2822
2823 While testing, we recommend turning logging on in the configuration file
2824 to provide us with diagnostic information:
2825   log {
2826         file="/tmp/lvm2.log"
2827         level=7
2828         activation=1
2829   }
2830
2831 You should schedule regular backups of your configuration file and
2832 metadata backups and archives (normally kept under /etc/lvm).
2833
2834 Please read docs/example.conf and "man lvm.conf" to find out more about
2835 the configuration file.
2836
2837 To convert an existing volume group called vg1 to the new format using
2838 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2839
2840 -M (or --metadatatype in its long form) is a new flag to indicate which
2841 format of metadata the command should use for anything it creates.
2842 Currently, the valid types are "lvm1" and "lvm2" and they can be
2843 abbreviated to "1" and "2" respectively.  The default value for this
2844 flag can be changed in the global section in the config file.
2845
2846 Backwards-compatible support for the original LVM1 metadata format is
2847 maintained, but it can be moved into a shared library or removed
2848 completely with configure's --with-lvm1 option.
2849
2850 Under LVM2, the basic unit of metadata is the volume group.  Different
2851 volume groups can use different formats of metadata - vg1 could use
2852 the original LVM1 format while vg2 used the new format - but you can't
2853 mix formats within a volume group.  So to add a PV to an LVM2-format
2854 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2855
2856 With LVM2-format metadata, lvextend will let you specify striping
2857 parameters.  So an LV could consist of two or more "segments" - the
2858 first segment could have 3 stripes while the second segment has just 2.
2859
2860 LVM2 maintains a backup of the current metadata for each volume group
2861 in /etc/lvm/backup, and puts copies of previous versions in
2862 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2863 create and restore from these files.  If you fully understand what
2864 you're doing, metadata can be changed by editing a copy of a current
2865 backup file and using vgcfgrestore to reload it.
2866
2867 Please read the pvcreate man page for more information on the new
2868 format for metadata.
2869
2870 All tools that can change things have a --test flag which can be used
2871 to check the effect  of a set of cmdline args without really making the
2872 changes.
2873
2874
2875 What's not finished?
2876 ====================
2877 The internal cache.  If you turn on debugging output you'll see lots of
2878 repeated messages, many of which will eventually get optimised out.
2879
2880 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2881 though the real command would work: again, fixing this is waiting for
2882 the work on the cache.
2883
2884 Several of the tools do not yet contain the logic to handle full
2885 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2886 needed to restore metadata if a tool gets interrupted or crashes or
2887 finds something unexpected.  This applies particularly to tools that
2888 work on more than one volume group at once (e.g. vgsplit).
2889
2890 Display output.  Some metadata information cannot yet be displayed.
2891
2892 Recovery tools to salvage "lost" metadata directly from the disks:
2893 but we hope the new format will mean such tools are hardly ever needed!
