2815
2816 Friday 14th November 2003
2817 =========================
2818 Some bug fixes & minor enhancements, including:
2819   Backwards compatibility with LVM1 metadata improved.
2820   Missing man pages written.
2821   Tool error codes made more consistent.
2822   vgmknodes written.
2823   O_DIRECT can be turned off if it doesn't work in your kernel.
2824   dumpconfig to display the active configuration file
2825
2826 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2827 If your root filesystem is on an LV, you should run one of those two
2828 commands to fix up the special files in /dev in your real root filesystem
2829 after finishing with your initrd.  Also, remember you can use
2830 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2831 it can't write a lock file to a read-only filesystem.
2832
2833 Wednesday 30th April 2003
2834 =========================
2835 A pvmove implementation is now available for the new metadata format.
2836
2837 When running a command that allocates space (e.g. lvcreate), you can now
2838 restrict not only which disk(s) may be used but also the Physical Extents
2839 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2840
2841
2842 Monday 18th November 2002
2843 ========================
2844
2845 The new format of LVM metadata is ready for you to test!
2846   We expect it to be more efficient and more robust than the original format.
2847   It's more compact and supports transactional changes and replication.
2848   Should things go wrong on a system, it's human-readable (and editable).
2849
2850 Please report any problems you find to the mailing list,
2851 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2852 tested and so quite possibly there'll still be some bugs in it.
2853 Be aware of the disclaimer in the COPYING file.
2854
2855 While testing, we recommend turning logging on in the configuration file
2856 to provide us with diagnostic information:
2857   log {
2858         file="/tmp/lvm2.log"
2859         level=7
2860         activation=1
2861   }
2862
2863 You should schedule regular backups of your configuration file and
2864 metadata backups and archives (normally kept under /etc/lvm).
2865
2866 Please read docs/example.conf and "man lvm.conf" to find out more about
2867 the configuration file.
2868
2869 To convert an existing volume group called vg1 to the new format using
2870 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2871
2872 -M (or --metadatatype in its long form) is a new flag to indicate which
2873 format of metadata the command should use for anything it creates.
2874 Currently, the valid types are "lvm1" and "lvm2" and they can be
2875 abbreviated to "1" and "2" respectively.  The default value for this
2876 flag can be changed in the global section in the config file.
2877
2878 Backwards-compatible support for the original LVM1 metadata format is
2879 maintained, but it can be moved into a shared library or removed
2880 completely with configure's --with-lvm1 option.
2881
2882 Under LVM2, the basic unit of metadata is the volume group.  Different
2883 volume groups can use different formats of metadata - vg1 could use
2884 the original LVM1 format while vg2 used the new format - but you can't
2885 mix formats within a volume group.  So to add a PV to an LVM2-format
2886 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2887
2888 With LVM2-format metadata, lvextend will let you specify striping
2889 parameters.  So an LV could consist of two or more "segments" - the
2890 first segment could have 3 stripes while the second segment has just 2.
2891
2892 LVM2 maintains a backup of the current metadata for each volume group
2893 in /etc/lvm/backup, and puts copies of previous versions in
2894 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2895 create and restore from these files.  If you fully understand what
2896 you're doing, metadata can be changed by editing a copy of a current
2897 backup file and using vgcfgrestore to reload it.
2898
2899 Please read the pvcreate man page for more information on the new
2900 format for metadata.
2901
2902 All tools that can change things have a --test flag which can be used
2903 to check the effect  of a set of cmdline args without really making the
2904 changes.
2905
2906
2907 What's not finished?
2908 ====================
2909 The internal cache.  If you turn on debugging output you'll see lots of
2910 repeated messages, many of which will eventually get optimised out.
2911
2912 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2913 though the real command would work: again, fixing this is waiting for
2914 the work on the cache.
2915
2916 Several of the tools do not yet contain the logic to handle full
2917 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
2918 needed to restore metadata if a tool gets interrupted or crashes or
2919 finds something unexpected.  This applies particularly to tools that
2920 work on more than one volume group at once (e.g. vgsplit).
2921
2922 Display output.  Some metadata information cannot yet be displayed.
2923
2924 Recovery tools to salvage "lost" metadata directly from the disks:
2925 but we hope the new format will mean such tools are hardly ever needed!
