2812
2813 Friday 14th November 2003
2814 =========================
2815 Some bug fixes & minor enhancements, including:
2816   Backwards compatibility with LVM1 metadata improved.
2817   Missing man pages written.
2818   Tool error codes made more consistent.
2819   vgmknodes written.
2820   O_DIRECT can be turned off if it doesn't work in your kernel.
2821   dumpconfig to display the active configuration file
2822
2823 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2824 If your root filesystem is on an LV, you should run one of those two
2825 commands to fix up the special files in /dev in your real root filesystem
2826 after finishing with your initrd.  Also, remember you can use
2827 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2828 it can't write a lock file to a read-only filesystem.
2829
2830 Wednesday 30th April 2003
2831 =========================
2832 A pvmove implementation is now available for the new metadata format.
2833
2834 When running a command that allocates space (e.g. lvcreate), you can now
2835 restrict not only which disk(s) may be used but also the Physical Extents
2836 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2837
2838
2839 Monday 18th November 2002
2840 ========================
2841
2842 The new format of LVM metadata is ready for you to test!
2843   We expect it to be more efficient and more robust than the original format.
2844   It's more compact and supports transactional changes and replication.
2845   Should things go wrong on a system, it's human-readable (and editable).
2846
2847 Please report any problems you find to the mailing list,
2848 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2849 tested and so quite possibly there'll still be some bugs in it.
2850 Be aware of the disclaimer in the COPYING file.
2851
2852 While testing, we recommend turning logging on in the configuration file
2853 to provide us with diagnostic information:
2854   log {
2855         file="/tmp/lvm2.log"
2856         level=7
2857         activation=1
2858   }
2859
2860 You should schedule regular backups of your configuration file and
2861 metadata backups and archives (normally kept under /etc/lvm).
2862
2863 Please read docs/example.conf and "man lvm.conf" to find out more about
2864 the configuration file.
2865
2866 To convert an existing volume group called vg1 to the new format using
2867 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2868
2869 -M (or --metadatatype in its long form) is a new flag to indicate which
2870 format of metadata the command should use for anything it creates.
2871 Currently, the valid types are "lvm1" and "lvm2" and they can be
2872 abbreviated to "1" and "2" respectively.  The default value for this
2873 flag can be changed in the global section in the config file.
2874
2875 Backwards-compatible support for the original LVM1 metadata format is
2876 maintained, but it can be moved into a shared library or removed
2877 completely with configure's --with-lvm1 option.
2878
2879 Under LVM2, the basic unit of metadata is the volume group.  Different
2880 volume groups can use different formats of metadata - vg1 could use
2881 the original LVM1 format while vg2 used the new format - but you can't
2882 mix formats within a volume group.  So to add a PV to an LVM2-format
2883 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2884
2885 With LVM2-format metadata, lvextend will let you specify striping
2886 parameters.  So an LV could consist of two or more "segments" - the
2887 first segment could have 3 stripes while the second segment has just 2.
2888
2889 LVM2 maintains a backup of the current metadata for each volume group
2890 in /etc/lvm/backup, and puts copies of previous versions in
2891 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2892 create and restore from these files.  If you fully understand what
2893 you're doing, metadata can be changed by editing a copy of a current
2894 backup file and using vgcfgrestore to reload it.
2895
2896 Please read the pvcreate man page for more information on the new
2897 format for metadata.
2898
2899 All tools that can change things have a --test flag which can be used
2900 to check the effect  of a set of cmdline args without really making the
2901 changes.
2902
2903
2904 What's not finished?
2905 ====================
2906 The internal cache.  If you turn on debugging output you'll see lots of
2907 repeated messages, many of which will eventually get optimised out.
2908
2909 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2910 though the real command would work: again, fixing this is waiting for
2911 the work on the cache.
2912
2913 Several of the tools do not yet contain the logic to handle full
2914 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2915 needed to restore metadata if a tool gets interrupted or crashes or
2916 finds something unexpected.  This applies particularly to tools that
2917 work on more than one volume group at once (e.g. vgsplit).
2918
2919 Display output.  Some metadata information cannot yet be displayed.
2920
2921 Recovery tools to salvage "lost" metadata directly from the disks:
2922 but we hope the new format will mean such tools are hardly ever needed!
