2800
2801 Friday 14th November 2003
2802 =========================
2803 Some bug fixes & minor enhancements, including:
2804   Backwards compatibility with LVM1 metadata improved.
2805   Missing man pages written.
2806   Tool error codes made more consistent.
2807   vgmknodes written.
2808   O_DIRECT can be turned off if it doesn't work in your kernel.
2809   dumpconfig to display the active configuration file
2810
2811 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2812 If your root filesystem is on an LV, you should run one of those two
2813 commands to fix up the special files in /dev in your real root filesystem
2814 after finishing with your initrd.  Also, remember you can use
2815 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2816 it can't write a lock file to a read-only filesystem.
2817
2818 Wednesday 30th April 2003
2819 =========================
2820 A pvmove implementation is now available for the new metadata format.
2821
2822 When running a command that allocates space (e.g. lvcreate), you can now
2823 restrict not only which disk(s) may be used but also the Physical Extents
2824 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2825
2826
2827 Monday 18th November 2002
2828 ========================
2829
2830 The new format of LVM metadata is ready for you to test!
2831   We expect it to be more efficient and more robust than the original format.
2832   It's more compact and supports transactional changes and replication.
2833   Should things go wrong on a system, it's human-readable (and editable).
2834
2835 Please report any problems you find to the mailing list,
2836 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2837 tested and so quite possibly there'll still be some bugs in it.
2838 Be aware of the disclaimer in the COPYING file.
2839
2840 While testing, we recommend turning logging on in the configuration file
2841 to provide us with diagnostic information:
2842   log {
2843         file="/tmp/lvm2.log"
2844         level=7
2845         activation=1
2846   }
2847
2848 You should schedule regular backups of your configuration file and
2849 metadata backups and archives (normally kept under /etc/lvm).
2850
2851 Please read docs/example.conf and "man lvm.conf" to find out more about
2852 the configuration file.
2853
2854 To convert an existing volume group called vg1 to the new format using
2855 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2856
2857 -M (or --metadatatype in its long form) is a new flag to indicate which
2858 format of metadata the command should use for anything it creates.
2859 Currently, the valid types are "lvm1" and "lvm2" and they can be
2860 abbreviated to "1" and "2" respectively.  The default value for this
2861 flag can be changed in the global section in the config file.
2862
2863 Backwards-compatible support for the original LVM1 metadata format is
2864 maintained, but it can be moved into a shared library or removed
2865 completely with configure's --with-lvm1 option.
2866
2867 Under LVM2, the basic unit of metadata is the volume group.  Different
2868 volume groups can use different formats of metadata - vg1 could use
2869 the original LVM1 format while vg2 used the new format - but you can't
2870 mix formats within a volume group.  So to add a PV to an LVM2-format
2871 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2872
2873 With LVM2-format metadata, lvextend will let you specify striping
2874 parameters.  So an LV could consist of two or more "segments" - the
2875 first segment could have 3 stripes while the second segment has just 2.
2876
2877 LVM2 maintains a backup of the current metadata for each volume group
2878 in /etc/lvm/backup, and puts copies of previous versions in
2879 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2880 create and restore from these files.  If you fully understand what
2881 you're doing, metadata can be changed by editing a copy of a current
2882 backup file and using vgcfgrestore to reload it.
2883
2884 Please read the pvcreate man page for more information on the new
2885 format for metadata.
2886
2887 All tools that can change things have a --test flag which can be used
2888 to check the effect  of a set of cmdline args without really making the
2889 changes.
2890
2891
2892 What's not finished?
2893 ====================
2894 The internal cache.  If you turn on debugging output you'll see lots of
2895 repeated messages, many of which will eventually get optimised out.
2896
2897 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2898 though the real command would work: again, fixing this is waiting for
2899 the work on the cache.
2900
2901 Several of the tools do not yet contain the logic to handle full
2902 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2903 needed to restore metadata if a tool gets interrupted or crashes or
2904 finds something unexpected.  This applies particularly to tools that
2905 work on more than one volume group at once (e.g. vgsplit).
2906
2907 Display output.  Some metadata information cannot yet be displayed.
2908
2909 Recovery tools to salvage "lost" metadata directly from the disks:
2910 but we hope the new format will mean such tools are hardly ever needed!
