2822
2823 Friday 14th November 2003
2824 =========================
2825 Some bug fixes & minor enhancements, including:
2826   Backwards compatibility with LVM1 metadata improved.
2827   Missing man pages written.
2828   Tool error codes made more consistent.
2829   vgmknodes written.
2830   O_DIRECT can be turned off if it doesn't work in your kernel.
2831   dumpconfig to display the active configuration file
2832
2833 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2834 If your root filesystem is on an LV, you should run one of those two
2835 commands to fix up the special files in /dev in your real root filesystem
2836 after finishing with your initrd.  Also, remember you can use
2837 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2838 it can't write a lock file to a read-only filesystem.
2839
2840 Wednesday 30th April 2003
2841 =========================
2842 A pvmove implementation is now available for the new metadata format.
2843
2844 When running a command that allocates space (e.g. lvcreate), you can now
2845 restrict not only which disk(s) may be used but also the Physical Extents
2846 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2847
2848
2849 Monday 18th November 2002
2850 ========================
2851
2852 The new format of LVM metadata is ready for you to test!
2853   We expect it to be more efficient and more robust than the original format.
2854   It's more compact and supports transactional changes and replication.
2855   Should things go wrong on a system, it's human-readable (and editable).
2856
2857 Please report any problems you find to the mailing list,
2858 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2859 tested and so quite possibly there'll still be some bugs in it.
2860 Be aware of the disclaimer in the COPYING file.
2861
2862 While testing, we recommend turning logging on in the configuration file
2863 to provide us with diagnostic information:
2864   log {
2865         file="/tmp/lvm2.log"
2866         level=7
2867         activation=1
2868   }
2869
2870 You should schedule regular backups of your configuration file and
2871 metadata backups and archives (normally kept under /etc/lvm).
2872
2873 Please read docs/example.conf and "man lvm.conf" to find out more about
2874 the configuration file.
2875
2876 To convert an existing volume group called vg1 to the new format using
2877 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2878
2879 -M (or --metadatatype in its long form) is a new flag to indicate which
2880 format of metadata the command should use for anything it creates.
2881 Currently, the valid types are "lvm1" and "lvm2" and they can be
2882 abbreviated to "1" and "2" respectively.  The default value for this
2883 flag can be changed in the global section in the config file.
2884
2885 Backwards-compatible support for the original LVM1 metadata format is
2886 maintained, but it can be moved into a shared library or removed
2887 completely with configure's --with-lvm1 option.
2888
2889 Under LVM2, the basic unit of metadata is the volume group.  Different
2890 volume groups can use different formats of metadata - vg1 could use
2891 the original LVM1 format while vg2 used the new format - but you can't
2892 mix formats within a volume group.  So to add a PV to an LVM2-format
2893 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2894
2895 With LVM2-format metadata, lvextend will let you specify striping
2896 parameters.  So an LV could consist of two or more "segments" - the
2897 first segment could have 3 stripes while the second segment has just 2.
2898
2899 LVM2 maintains a backup of the current metadata for each volume group
2900 in /etc/lvm/backup, and puts copies of previous versions in
2901 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2902 create and restore from these files.  If you fully understand what
2903 you're doing, metadata can be changed by editing a copy of a current
2904 backup file and using vgcfgrestore to reload it.
2905
2906 Please read the pvcreate man page for more information on the new
2907 format for metadata.
2908
2909 All tools that can change things have a --test flag which can be used
2910 to check the effect  of a set of cmdline args without really making the
2911 changes.
2912
2913
2914 What's not finished?
2915 ====================
2916 The internal cache.  If you turn on debugging output you'll see lots of
2917 repeated messages, many of which will eventually get optimised out.
2918
2919 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2920 though the real command would work: again, fixing this is waiting for
2921 the work on the cache.
2922
2923 Several of the tools do not yet contain the logic to handle full
2924 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2925 needed to restore metadata if a tool gets interrupted or crashes or
2926 finds something unexpected.  This applies particularly to tools that
2927 work on more than one volume group at once (e.g. vgsplit).
2928
2929 Display output.  Some metadata information cannot yet be displayed.
2930
2931 Recovery tools to salvage "lost" metadata directly from the disks:
2932 but we hope the new format will mean such tools are hardly ever needed!
