2897
2898 Friday 14th November 2003
2899 =========================
2900 Some bug fixes & minor enhancements, including:
2901   Backwards compatibility with LVM1 metadata improved.
2902   Missing man pages written.
2903   Tool error codes made more consistent.
2904   vgmknodes written.
2905   O_DIRECT can be turned off if it doesn't work in your kernel.
2906   dumpconfig to display the active configuration file
2907
2908 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2909 If your root filesystem is on an LV, you should run one of those two
2910 commands to fix up the special files in /dev in your real root filesystem
2911 after finishing with your initrd.  Also, remember you can use
2912 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2913 it can't write a lock file to a read-only filesystem.
2914
2915 Wednesday 30th April 2003
2916 =========================
2917 A pvmove implementation is now available for the new metadata format.
2918
2919 When running a command that allocates space (e.g. lvcreate), you can now
2920 restrict not only which disk(s) may be used but also the Physical Extents
2921 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2922
2923
2924 Monday 18th November 2002
2925 ========================
2926
2927 The new format of LVM metadata is ready for you to test!
2928   We expect it to be more efficient and more robust than the original format.
2929   It's more compact and supports transactional changes and replication.
2930   Should things go wrong on a system, it's human-readable (and editable).
2931
2932 Please report any problems you find to the mailing list,
2933 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2934 tested and so quite possibly there'll still be some bugs in it.
2935 Be aware of the disclaimer in the COPYING file.
2936
2937 While testing, we recommend turning logging on in the configuration file
2938 to provide us with diagnostic information:
2939   log {
2940         file="/tmp/lvm2.log"
2941         level=7
2942         activation=1
2943   }
2944
2945 You should schedule regular backups of your configuration file and
2946 metadata backups and archives (normally kept under /etc/lvm).
2947
2948 Please read docs/example.conf and "man lvm.conf" to find out more about
2949 the configuration file.
2950
2951 To convert an existing volume group called vg1 to the new format using
2952 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2953
2954 -M (or --metadatatype in its long form) is a new flag to indicate which
2955 format of metadata the command should use for anything it creates.
2956 Currently, the valid types are "lvm1" and "lvm2" and they can be
2957 abbreviated to "1" and "2" respectively.  The default value for this
2958 flag can be changed in the global section in the config file.
2959
2960 Backwards-compatible support for the original LVM1 metadata format is
2961 maintained, but it can be moved into a shared library or removed
2962 completely with configure's --with-lvm1 option.
2963
2964 Under LVM2, the basic unit of metadata is the volume group.  Different
2965 volume groups can use different formats of metadata - vg1 could use
2966 the original LVM1 format while vg2 used the new format - but you can't
2967 mix formats within a volume group.  So to add a PV to an LVM2-format
2968 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2969
2970 With LVM2-format metadata, lvextend will let you specify striping
2971 parameters.  So an LV could consist of two or more "segments" - the
2972 first segment could have 3 stripes while the second segment has just 2.
2973
2974 LVM2 maintains a backup of the current metadata for each volume group
2975 in /etc/lvm/backup, and puts copies of previous versions in
2976 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2977 create and restore from these files.  If you fully understand what
2978 you're doing, metadata can be changed by editing a copy of a current
2979 backup file and using vgcfgrestore to reload it.
2980
2981 Please read the pvcreate man page for more information on the new
2982 format for metadata.
2983
2984 All tools that can change things have a --test flag which can be used
2985 to check the effect  of a set of cmdline args without really making the
2986 changes.
2987
2988
2989 What's not finished?
2990 ====================
2991 The internal cache.  If you turn on debugging output you'll see lots of
2992 repeated messages, many of which will eventually get optimised out.
2993
2994 --test sometimes causes a command to fail (e.g. vgconvert --test) even
2995 though the real command would work: again, fixing this is waiting for
2996 the work on the cache.
2997
2998 Several of the tools do not yet contain the logic to handle full
2999 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
3000 needed to restore metadata if a tool gets interrupted or crashes or
3001 finds something unexpected.  This applies particularly to tools that
3002 work on more than one volume group at once (e.g. vgsplit).
3003
3004 Display output.  Some metadata information cannot yet be displayed.
3005
3006 Recovery tools to salvage "lost" metadata directly from the disks:
3007 but we hope the new format will mean such tools are hardly ever needed!
