2824
2825 Friday 14th November 2003
2826 =========================
2827 Some bug fixes & minor enhancements, including:
2828   Backwards compatibility with LVM1 metadata improved.
2829   Missing man pages written.
2830   Tool error codes made more consistent.
2831   vgmknodes written.
2832   O_DIRECT can be turned off if it doesn't work in your kernel.
2833   dumpconfig to display the active configuration file
2834
2835 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2836 If your root filesystem is on an LV, you should run one of those two
2837 commands to fix up the special files in /dev in your real root filesystem
2838 after finishing with your initrd.  Also, remember you can use
2839 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2840 it can't write a lock file to a read-only filesystem.
2841
2842 Wednesday 30th April 2003
2843 =========================
2844 A pvmove implementation is now available for the new metadata format.
2845
2846 When running a command that allocates space (e.g. lvcreate), you can now
2847 restrict not only which disk(s) may be used but also the Physical Extents
2848 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2849
2850
2851 Monday 18th November 2002
2852 ========================
2853
2854 The new format of LVM metadata is ready for you to test!
2855   We expect it to be more efficient and more robust than the original format.
2856   It's more compact and supports transactional changes and replication.
2857   Should things go wrong on a system, it's human-readable (and editable).
2858
2859 Please report any problems you find to the mailing list,
2860 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2861 tested and so quite possibly there'll still be some bugs in it.
2862 Be aware of the disclaimer in the COPYING file.
2863
2864 While testing, we recommend turning logging on in the configuration file
2865 to provide us with diagnostic information:
2866   log {
2867         file="/tmp/lvm2.log"
2868         level=7
2869         activation=1
2870   }
2871
2872 You should schedule regular backups of your configuration file and
2873 metadata backups and archives (normally kept under /etc/lvm).
2874
2875 Please read docs/example.conf and "man lvm.conf" to find out more about
2876 the configuration file.
2877
2878 To convert an existing volume group called vg1 to the new format using
2879 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2880
2881 -M (or --metadatatype in its long form) is a new flag to indicate which
2882 format of metadata the command should use for anything it creates.
2883 Currently, the valid types are "lvm1" and "lvm2" and they can be
2884 abbreviated to "1" and "2" respectively.  The default value for this
2885 flag can be changed in the global section in the config file.
2886
2887 Backwards-compatible support for the original LVM1 metadata format is
2888 maintained, but it can be moved into a shared library or removed
2889 completely with configure's --with-lvm1 option.
2890
2891 Under LVM2, the basic unit of metadata is the volume group.  Different
2892 volume groups can use different formats of metadata - vg1 could use
2893 the original LVM1 format while vg2 used the new format - but you can't
2894 mix formats within a volume group.  So to add a PV to an LVM2-format
2895 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2896
2897 With LVM2-format metadata, lvextend will let you specify striping
2898 parameters.  So an LV could consist of two or more "segments" - the
2899 first segment could have 3 stripes while the second segment has just 2.
2900
2901 LVM2 maintains a backup of the current metadata for each volume group
2902 in /etc/lvm/backup, and puts copies of previous versions in
2903 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2904 create and restore from these files.  If you fully understand what
2905 you're doing, metadata can be changed by editing a copy of a current
2906 backup file and using vgcfgrestore to reload it.
2907
2908 Please read the pvcreate man page for more information on the new
2909 format for metadata.
2910
2911 All tools that can change things have a --test flag which can be used
2912 to check the effect  of a set of cmdline args without really making the
2913 changes.
2914
2915
2916 What's not finished?
2917 ====================
2918 The internal cache.  If you turn on debugging output you'll see lots of
2919 repeated messages, many of which will eventually get optimised out.
2920
2921 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2922 though the real command would work: again, fixing this is waiting for
2923 the work on the cache.
2924
2925 Several of the tools do not yet contain the logic to handle full
2926 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2927 needed to restore metadata if a tool gets interrupted or crashes or
2928 finds something unexpected.  This applies particularly to tools that
2929 work on more than one volume group at once (e.g. vgsplit).
2930
2931 Display output.  Some metadata information cannot yet be displayed.
2932
2933 Recovery tools to salvage "lost" metadata directly from the disks:
2934 but we hope the new format will mean such tools are hardly ever needed!
