2919
2920 Friday 14th November 2003
2921 =========================
2922 Some bug fixes & minor enhancements, including:
2923   Backwards compatibility with LVM1 metadata improved.
2924   Missing man pages written.
2925   Tool error codes made more consistent.
2926   vgmknodes written.
2927   O_DIRECT can be turned off if it doesn't work in your kernel.
2928   dumpconfig to display the active configuration file
2929
2930 You need to update libdevmapper before using 'vgmknodes' or 'vgscan --mknodes'.
2931 If your root filesystem is on an LV, you should run one of those two
2932 commands to fix up the special files in /dev in your real root filesystem
2933 after finishing with your initrd.  Also, remember you can use
2934 'vgchange --ignorelockingfailure' on your initrd if the tool fails because
2935 it can't write a lock file to a read-only filesystem.
2936
2937 Wednesday 30th April 2003
2938 =========================
2939 A pvmove implementation is now available for the new metadata format.
2940
2941 When running a command that allocates space (e.g. lvcreate), you can now
2942 restrict not only which disk(s) may be used but also the Physical Extents
2943 on those disks.  e.g. lvcreate -L 10 vg1 /dev/hda6:1000-2000:3000-4000
2944
2945
2946 Monday 18th November 2002
2947 ========================
2948
2949 The new format of LVM metadata is ready for you to test!
2950   We expect it to be more efficient and more robust than the original format.
2951   It's more compact and supports transactional changes and replication.
2952   Should things go wrong on a system, it's human-readable (and editable).
2953
2954 Please report any problems you find to the mailing list,
2955 linux-lvm@sistina.com.  The software has NOT yet been thoroughly
2956 tested and so quite possibly there'll still be some bugs in it.
2957 Be aware of the disclaimer in the COPYING file.
2958
2959 While testing, we recommend turning logging on in the configuration file
2960 to provide us with diagnostic information:
2961   log {
2962         file="/tmp/lvm2.log"
2963         level=7
2964         activation=1
2965   }
2966
2967 You should schedule regular backups of your configuration file and
2968 metadata backups and archives (normally kept under /etc/lvm).
2969
2970 Please read docs/example.conf and "man lvm.conf" to find out more about
2971 the configuration file.
2972
2973 To convert an existing volume group called vg1 to the new format using
2974 the default settings, use "vgconvert -M2 vg1".  See "man vgconvert".
2975
2976 -M (or --metadatatype in its long form) is a new flag to indicate which
2977 format of metadata the command should use for anything it creates.
2978 Currently, the valid types are "lvm1" and "lvm2" and they can be
2979 abbreviated to "1" and "2" respectively.  The default value for this
2980 flag can be changed in the global section in the config file.
2981
2982 Backwards-compatible support for the original LVM1 metadata format is
2983 maintained, but it can be moved into a shared library or removed
2984 completely with configure's --with-lvm1 option.
2985
2986 Under LVM2, the basic unit of metadata is the volume group.  Different
2987 volume groups can use different formats of metadata - vg1 could use
2988 the original LVM1 format while vg2 used the new format - but you can't
2989 mix formats within a volume group.  So to add a PV to an LVM2-format
2990 volume group you must run "pvcreate -M2" on it, followed by "vgextend".
2991
2992 With LVM2-format metadata, lvextend will let you specify striping
2993 parameters.  So an LV could consist of two or more "segments" - the
2994 first segment could have 3 stripes while the second segment has just 2.
2995
2996 LVM2 maintains a backup of the current metadata for each volume group
2997 in /etc/lvm/backup, and puts copies of previous versions in
2998 /etc/lvm/archive.  "vgcfgbackup" and "vgcfgrestore" can be used to
2999 create and restore from these files.  If you fully understand what
3000 you're doing, metadata can be changed by editing a copy of a current
3001 backup file and using vgcfgrestore to reload it.
3002
3003 Please read the pvcreate man page for more information on the new
3004 format for metadata.
3005
3006 All tools that can change things have a --test flag which can be used
3007 to check the effect  of a set of cmdline args without really making the
3008 changes.
3009
3010
3011 What's not finished?
3012 ====================
3013 The internal cache.  If you turn on debugging output you'll see lots of
3014 repeated messages, many of which will eventually get optimised out.
3015
3016 --test sometimes causes a command to fail (e.g. vgconvert --test) even
3017 though the real command would work: again, fixing this is waiting for
3018 the work on the cache.
3019
3020 Several of the tools do not yet contain the logic to handle full
3021 recovery: combinations of pvcreate and vgcfgrestore may sometimes be
3022 needed to restore metadata if a tool gets interrupted or crashes or
3023 finds something unexpected.  This applies particularly to tools that
3024 work on more than one volume group at once (e.g. vgsplit).
3025
3026 Display output.  Some metadata information cannot yet be displayed.
3027
3028 Recovery tools to salvage "lost" metadata directly from the disks:
3029 but we hope the new format will mean such tools are hardly ever needed!
